Low MPG puzzle

So, my intuition to reach out to this forum is turning out to be a potential lifesaver. I am acquiring a larger, 8'x10' storage space that will give me some room to do more work myself. I've done timing belt and brakes on my 1200 Gold Wing years ago, so I am not a total dummy, but this is a different animal.
A deceiving factor regarding the brakes is the fact that the guy I bought the bike from delivered it to my place from 35 miles away, hence the assumption, "he didn't die, therefore all is well, nothing to worry about."

I have since logged just over 500 miles, mostly in town and back roads, took it to the freeway after I got more comfortable, and revved it up to 100 MPH for about 5 seconds to get out of the bad spot I was in.
That gave me some confidence. That old goat sure can pull hard when it counts, but now, I am only going to move it into a new storage unit 1/2 mile down the street, closer to home.

I called a local guy who restores old Japanese bikes; he has a reputable shop, too busy at the moment, asked me to get back to him in 4 weeks, no more rides till things are taken care of.

I do have a question for you gurus:
Can a linked braking system be simplified by ditching the connection without a major headache?
Bells and whistles on newer bikes seem to be more dangerous than old goats that required some skills and were safer in the long run due to simplicity.
 
While you are improving brake performance trying to get more than 3/4 of a turn out of your wheels, think how useful it woul be to know how the wheels spin when the pads are removed - 'cos it isn't going to get any better than that.

Just saying that there my be two issues here - brakes and bearings binding.
 
I miss my 1987 GL1200 Gold Wing Interstate. Everything I researched about ST1300 suggested it is the closest thing to it, with some useful advances, but I am getting more disappointed by the hour.
The larger storage unit I tried to get turned out to be falsely advertised and not suited for my purpose, with no drive-up access. If the local shop doesn't come through, I'll have to get rid of it at a loss.
I just don't have space to work on more complex issues.

That bike would now be 38 years old. The oldest ST1300 would be 23 years old. Quite a difference. Get a Guzzi T3...you can repair that bike in a parking lot with a handful of tools. And it too will run forever.

I really hope reaching out to us here was NOT a matter of life and death.

The linked braking system can be simplified at great expense and a good deal of work. Headaches are not necessarily part of the work, but certain pejorative words help.

Older bikes safer due to simplicity? What car do you drive? A model A Ford? Why not a Model T? We can debate this ad nauseum, but I doubt many folks here will agree older bikes, cars, planes, tools, pick your poison are safer than modern iterations. One of my current debates centers around a common table saw vs. a SawStop table saw. There is no question the latter is safer or the former is more simple. However, it is virtually impossible to cut your finger off on a SawStop saw but it is childishly easy to lop off a few digits on any other brand of saw.
 
Life and death not being a reason,.... until it becomes a real possibility due to lack of awareness and progressively deteriorating mechanical issue.
Simplicity in older bikes made it possible for a large number of owners to take care of problems that did not require a college degree in engineering or, at the very least, extensive training in a particular model of bike or car service.

I drive a 2004 Toyota Rav4 standard front wheel drive, 5-speed manual, 84K on the clock, runs like the day it got off the assembly line. I am the second owner, the car is so boring, it's depressing, but it gets me where I need to go. Oh, it has buttons too, power windows and locks, AC, and traction control,..... I don't remember what I did to it last in the service department besides oil changes, never saw a dealer again, no blackmail OEM extortion scheme to worry about.
Technology is great while it works to benefit us, but when it fails, people die. Not all technology is implemented to benefit the end user, either. I am not against it, and yet I know it's dangerous if used recklessly.
I am most afraid of Tesla on autopilot creeping up behind me on the freeway, as it is known to have killed motorcyclists because it does not see a motorcycle as an obstacle comparable to another car.

So you see, exchanging information on here prompted me to step back from the next ride that could be my last, just because I was not fully aware of the problem that could lead to more than a bad hair day, and I would need hair for that to happen.
My ST1300 is grounded until a full inspection and overhaul for mechanical roadworthiness is done by a qualified mechanic, thanks to bits and pieces of info I connected while whining about low MPG, which by itself only costs me a bit more at the pump.
 
I've done some routine work, but anything requiring the removal of fairing is out for me; time to see the local shop and get the estimate on the overhaul of critical systems.
No need to fear... if you've dismantled a 1500 GoldWing, this will be a piece o' cake.
As mentioned, few shops or mechanics are familiar with the ST1300... you'll risk broken (EXPENSIVE!) fairing tabs and pieces, missing bolts and fasteners, and all kinds of needless problems.
Removing the plastics becomes easier after the first time or two, and IF you take it somewhere, you'll save money AND your unobtanium bodywork by removing it yourself before taking it to them.
And, as you may have guessed, there are articles on how to safely remove and replace the plastics, right here on this forum.

My last Goldwing was a 1987 GL1200; I never owned a 1500, 1200 had most of the motor exposed below the fairing, and carbs did not need any service either while I owned it.
The 1500 had all that plastic that I never cared for. ST has easy access to a few things that need the most attention, so that was not a big deal for me.
When I decided to get ST I was mostly trusting all the rhetoric about the bike being ultra reliable and low maintenance, but I guess that comes with good service history, something that is hard to verify on a 20-year-old bike.
My storage unit's actual measurements are 5'x 9', with utility poles partially obstructing access. I have to perform a precise maneuver to clear obstacles on the way in and out.
I considered 2004 ABS model with 20K but the dealer in Sacramento quoted me over $7000 with delivery, so I didn't want to pay that much for it. They still have it after months of trying to sell at a fixed price; it's about paying up front or paying later with used bikes, and $30 000 for a new bike is not happening.
 
I see you have an offer from Igofar for the white courtesy phone, I would take up the offer from what I have read on this forum, I certainly wouldn't be considering getting rid of the bike so soon, the fairing is just plastic covers that come off really easily and quickly, then it's just a motorcycle underneath (albeit an engineering masterpiece) and you have the support of this forum which will pretty much cover any issues you are likely to experience, and in a few months you'll have what you were looking for.....Just my 2cents :)
 
Thanks all for the quick replies. I'll try to filter out a few things to start with. The PO rode the bike as a commuter and in parking lot practice sessions.
He installed aftermarket fork springs and rear suspension, LED lights all around, a Sargent seat, front and back cameras, GPS, and new tires before sale. It seems he took real good care of it.
I had it sit in storage for about a month while working on regaining my M1 license that was lost after 15 years of not riding.
Initially, I managed to do some maintenance in 5' x 9' storage unit as mentioned before, only after riding for a while, I started paying attention to the digital display regarding fuel consumption.
Because nothing jumped at me as "defective," I just went through a few 2-hour rides a week before looking into it.
As always, I am prone to do something stupid even in the midst of trying to do the right thing, so I trashed old plugs after a few days of comparing them to online pictures of diagnostics.
All I can say now is they were all uniformly dark brown or black in spots, with no physical damage to electrodes and no clue as to how long they were in.

So far, both wheels are spinning freely while on the center stand, rotors show some wear but no gouging, the master cylinder window of the clutch and brake reservoirs show clear fluid.
Braking is buttery smooth, pads look good, recently installed.
As for temperature, I missed any sign of a gradual warm-up progress, so I'll pay attention to that on the next ride.
I read comments about "excessive heat" being produced by ST1300 in a few threads. I ride mostly in the morning hours when the temperature is around 70 degrees, by the time it goes to 80 and over, I am back home wiping smiles off of my face near AC.
I have no evidence of excessive heat on my legs, as some have complained about. Is that a good thing or a sign of trouble?

Looking back on all responses, I realise there may be an issue with a few things that I am not equipped to deal with due to a lack of space and expertise. I've done some routine work, but anything requiring the removal of fairing is out for me; time to see the local shop and get the estimate on the overhaul of critical systems.
I was looking for some thrill, a test of "do I still have it," perhaps, at the age of almost 69, I have no complaints, but I don't need a can of warms either, especially if a snake is hidden within.

Going to test the time it takes to reach 3 bars on the temperature gauge and report back later.
I have two ST's, one for ten years snow, the other for five. I rode our 1100 around for a bit making notes on what maintenance it likely needed. Ended up rebuilding the carbs, flushing the cooling system and replacing all the vent, fuel and water hoses....and several of the related fittings. Found lots marginal or just plain wrong.....my refurbishment tale is posted on here somewhere. Afterwards, the heat behavior was unremarkable.
Our 1300 has not displayed anything in the way of uncomfortable behavior.
I only have a heat issue now if I have to sit through more than one light change on either bike.

As I mentioned a few times, the main obstacle to doing my repairs is a lack of adequate space. I have Honda service manual, there is a YouTube university, and this forum with all the expertise one could want. I am not mechanically challenged, but the main obstacle remains. So, you may wonder why I bothered to log in here and report a low MPG issue, only to be led to a ticking bomb that I failed to see as the clock ticked towards both wheels potentially locking up in the middle of the freeway.
The simple answer is being blindsided by popular opinions that the bike is bulletproof, having no prior experience with the model, and ignoring common sense due to the bike's reputation as "bulletproof."
As a machinist, I often heard "Push it until it breaks, then back off a notch." That can mean a lot of things to a lot of people. Ideally, an experienced machinist can read the signs of s**t hitting the fan before it happens, then establish a safe zone of operation that preserves equipment, achieves maximum efficiency while protecting the operator from injuries, and still produces reasonable profit.
That balancing act is referred to as "experience," and they don't sell it at Walmart; it has to be earned, often painfully and over a long time.
Retired after 40 years with no dead bodies left behind, I am now faced with how much I want to risk to juggle another moving target without killing myself in the process.

Is love for motorcycling worth the danger, trouble, cost, and frustration of learning how far to push it before crashing and then backing off a notch, assuming one gets a second chance to back off a notch?
Ultimately, that's a decision each one of us has to make, and some priorities and obstacles may defy logic. As a result of jumping into this forum, I am better educated than the day before, which comes at no cost but plays a role in what happens next.
 
Wish you luck, given your stated work space limitations! Maybe there is someone local with more space willing to assist? That would solve the most pertinent problem and allow you 'space' to consider some of the other options besides paying a STealer to work on things that may not fix what you're experiencing. I've never been able to get my wheels to rotate 2-3 revolutions but check bearings, pads, SMC, etc regularly. I see upwards of 46mpg (US, instantaneous) regularly on the highway when I stay under the dreaded FI trigger RPM but it does drop when exceeded. Haven't ever checked/changed the thermostat yet either as I haven't observed the (likely?) drop in mpg that may indicate that as a problem. Functional check of SMC would be up there on my list of recommendations to you, as has been previously mentioned but I don't recall you talking about the functional test. Stay whatever course you choose, it's your ride!
 
If the bike has been sitting a while an unwanted guest may have built a cozy home in your airbox. My pickup sat outside my house for a couple of weeks and when I popped the hood I was amazed at the huge nest under construction around the air filter.

I changed air filter, oil, oil filter, oil drain plug, final drive oil, and spark plugs a week ago. The only thing that signalled trouble was plugs coated with carbon. As I moved on to try and learn the potential cause, I learned about other issues I would not have guessed on my own due to being unfamiliar with the model.
It all seems to boil down to the thermostat being stuck open, and SMC.
 
You have stated that you can not work on it yourself because you have no where to do so. Given that, no matter how many or what suggestion we make in an attempt to help you are all fruitless if you are not in a position to take advantage of them. You also can't find a local shop that can do it any reasonable time frame either. Added to that is even if you find a local shop that is willing to work on it they most likely will not have a high degree of familiarity with it. So, it is unfortunate that this kind of leaves you with a paperweight until you miraculously build a garage or some local shop that has a lot of ST1300 experience suddenly comes to your attention. I doubt that either is likely, so this leaves you in a bind.

This might seem like a ridiculous suggestion to you but here goes.
No shop that you will find will treat your ST1300 anywhere near as well as Larry, IGOFAR on this forum. He has already offered his assistance to you. I suggest that you take him up on his offer and discuss the possibility of taking your ST1300 to him in Tucson. If you can't get your hands on a truck or a trailer to get it there consider renting one and taking it to him. I know that it is about a 1,000 miles or so each way but consider this. If you take it to Larry the main problem that you came to this forum for will be fixed properly. In addition to that all of the other things that you have learned about, as well as all of the other things that you have no idea about, will also get fixed, adjusted, tweaked, etc., and they will de done properly. The bonus is that he will do the work with you and you will learn about the bike for the future. If it is cheaper to rent a U-Haul one way you can ride it back home. Once he has gone through it you will have the ST1300 that you dreamed of having and were expecting to have without any nagging questions about its condition.

In the end this might be cost effective relative to having someone local do the work for you. Larry isn't going to change all kind of parts, that you have to pay for, trying to fix a problem like someone else who has no familiarity with this bike might do. He also isn't going to half-ass anything. He has generously made an offer for you to call him. It cost you nothing to make that call and at least have a discussion with him.

No matter what the solution ends up being I hope that you can figure something out. It is always disheartening to read of someone who is disappointed by purchasing an ST1300. Let us know how you make out with it.
 
I have responded to Larry in a chat, and I never had any doubts about his genuine offer to help, nor do I question his qualifications, but taking on this project is not my option given the mentioned constraints and personal reasons.
It all started with me purchasing a used bike for the cheap thrill of returning to riding after a 15-year pause, but it turns out I stepped into a trap of my own making.
I am not in a position to travel to another state to resurrect this bike to its former glory, don't have space to work on it myself unless I manage to land a bigger storage unit at a reasonable cost.

I am thankful for all the advice on here, but I am not emotionally tied to this bike to the point of making it first priority in my life. I took a gamble on it, and it backfired.
I was asked to give the busy shop a call in 4 weeks, if there is a chance for a reasonable cost solution, okay, and if not, I am bailing out and cutting my losses, my ST 1300 is not a sacred cow that must be fixed at any cost or under any circumstances to keep the legend alive.
What may be rational to you may be unthinkable to me, even if I am inclined to agree with you, because there are many moving parts in the puzzle, and not all is up for debate.

Now, what if I set up a "GoFundMe page" to get some cash, buy myself a house with a double garage so I can fix my bike,.......... hmmmm , ..... it may be a stretch, better not go there.
 
This is a Genuine Honda Shop's repair (replaced the rear brake caliper) after the rear wheel locked up, because, well it had to be the rear calipers fault because its what locked up right?
Then the replacement destroyed itself in a few hundred miles again.....the shop never checked the SMC, or inspected the linked braking system.
And a word of caution about Certified Youtube Mechanics, they bring me a lot of work :rofl1:

I'll tiptoe into that quicksand...
Your GoFundMe, from what I've observed lately, may have a pretty good chance for success... but to really nail down a guaranteed return on that gamble, it would be helpful if you first unalive someone.
Some of the recent perpetrators have been amazed at the results, and have purchased a house. I don't know if a garage came with it, but it could happen.
If you choose not to take this route, ...I wouldn't blame you at all. Just throwing it out there; it certainly would not be my first choice.
 
And a word of caution about Certified Youtube Mechanics, they bring me a lot of work :rofl1:
I used to say that about the guys running around billing themselves as 'Handyman'. After they do a number on an electrical install, I get to do it correctly.:biggrin:
 
This is not about any one individual, post, or comment within, just got something that may explain where I stand on all this.

Since I have nothing better to do at the moment, I am going to share a personal story.
In the year 2002, I owned a 1981 Honda GL1100 GoldWing Aspencade; location is not important here. Went out for a ride, used brakes at the stop light before entering the freeway on ramp.
As I merged onto the freeway bike started to slow down abruptly, going from 60 MPH to half in a matter of seconds. I looked down at my right side and saw smoke. As I did that, I also unintentionally rolled on the throttle, therefore counteracting the wheel's inevitable lock-up by forcing power to the wheel and, at the same time, stopping at a shoulder.
I got off, put the bike on the center stand, and took a deep breath.
Rotor was hot and smoking, caliper solid brick, nothing moves, I just avoided a high side, and I was scared. I let the bike cool down, and afterwards, I used a wrench to bang on a caliper until it retracted pistons and released the rotor.

I rode home using only the front brake. The next day I took a bike to the closest shop, where they rebuilt the caliper and installed new pads. At that time, I did not dare to do my service; there were things to learn that came later.
I did ask to see old parts, including pads, which were worn at the angle, the front was thinner than the back, and they were about halfway worn.
This sheds some light on why the caliper locked up, uneven wear on pads forced pistons to misalign with the bore of the caliper, and get stuck. Friction produced heat, which expanded the rotor and locked the wheel.

I was told not to let pads wear out to that point again to prevent the problem from recurring. I sold the bike shortly after and, 2 years later, bought a 1983 GL1200 GoldWing Aspencade that was a joy to ride with no issues.
I sold that one about a year later, and in 2006 or 2007, I got my 1987 GL1200 GoldWing Interstate, fewer bells and whistles, better shape, lower mileage, sweet.
One day, I am looking at rear brake pads getting worn on an angle, I was now in a double garage doing all my service, and this got me pissed, really, Honda? again?
I flushed the fluid, rebuilt the calipers on both front and rear, but now I wanted nothing to do with locked-up wheels.
I designed and machined two pistons with self-adjusting tips that follow the wear of the pads but always keep the body of the pistons aligned with the bores of a caliper, therefore preventing jamming as pads wear and pistons get more exposed.

Not long after restoring that bike to an absolute best condition, I crashed on a mountain road at night after getting caught in the daylight saving time clock change.
The truck pulled next to me in the right lane in a long curve to the left, and I glanced at it. The next thing I know, I am heading straight into it instead of following the exit from the curve.

Two cracked ribs, broken right collarbone, and 3 months later, I am back at work and giving up motorcycles for good. State Farm paid me $5000 for the bike, which I handed over to insurance
as a deductible for medical bills and a helicopter ride. No idea what happened to the bike but my guess is that somebody got hold of it eventually.
I crashed at about 40 MPH, truck was going faster. When 1200 GoldWing is tipped over, it lies at about 45-degree angle, so the only damage would have been to the crash bars, but insurance totaled it.

Fast forward, life happened, and I applied for a job at a company named "Intuitive Surgical" in Sunnyvale CA, high-profile place. They make a surgical robot called DaVinchi, thing can peel skin off of a grape to demonstrate precision and capability.
In the course of the interview, the young engineer wants to know what makes me qualified to be a machinist in their R&D shop, which produces components for this robot with zero deviation from specification, tough call for any machinist, and who am I to think I am qualified and arrogant enough to seek the position.
Question: What have you accomplished to date to convince me to hire you as our top machinist?

Well, Sir, there are samples of my work connected to highly sophisticated instruments and assemblies used in aerospace, medical, and other fields, showing elaborate processes and methods of overcoming obstacles.
Guy stares at me like a deer in the headlights, and what specifically relates to our product? He asked.
Now I am desperate for a punch line. So I told him about my brake pistons that eliminate guess work in figuring out when to change brake pads on that old Wing to prevent wheel lock up.
Surely some creative thinking will impress the guy, I thought.
This is a DIY project I did to prevent a scary experience with my other bike having the same problem. So the dumbass says to me, "Why not just change pads sooner?
At this point, I knew I could not work there, and I said, "Because pads won't tell me when they are about to throw me off the bike, and changing them once a month is stupid."

I wasn't hired because I couldn't keep my mouth shut in the face of a dumbass "superior" challenging my logic with an idiotic comment.
So the moral of the story is, don't submit to idiots even when they are in charge, or maybe specifically because they are in charge, not everything is worth pursuing by any means necessary.

All my bikes were shaft-driven to date, and only the Suzuki VX800 was brand new, produced only during 2 years in early 1990 or 1991.
So, I am not shy about doing the work or learning new tricks; it's just not the time for getting all twisted into a pretzel to fix my bike in a 5'x 9' hole in the wall before the day is over. Let's just chill and see what tomorrow brings.

I know what it means to be good at what you do, and I hope to run into someone who can take on my issue here, locally, and if not, it will be time for a new chapter.
I could rent a space for a few months just to bring this bike up to snuff, but going back to a smaller unit could be loss; I have to sum up the cost of whatever I do.
