1991 ST1100 project

K, here's the plan. I'm leaving here early Friday, will land at Jay's house early Saturday. We'll do what we can 'til he has to quit for the day. I'll be free to do whatever the rest of Saturday 'til about noon on Sunday.

Dave, you gonna be working on yours?

I finally got the carb out, I will be ordering some of the parts tonight or tommorrow. I peeked inside the valve...well there is a little bit of gunk on a couple of them. And George I only have some basic tools what do you think I need aside from screwdrivers and some socket wrenches.

Don't worry Jay; he'll have both sides of his bike loaded down with tools!

Of course he will not need any other than a piece of straw, a brass thread and his mac-guy-ver... Oh... and some beer!

Shows how much you know. Coffee, I need coffee.

Jay, I'll have an assortment of tools (always do) including a couple of specialty tools. With what you have we'll be fine.

See ya Saturday morning.

Anxiously waiting the continuation of this thread.

BTW, I used a piece of 3/4 re bar the last time I pried the carbs up. Size was appropriate to the corner I was working in Oh. I used RTV Blue for lubricant when I set mine. I was very concerned about the age of the boots (isolaters) and the possibility of air leaks. I'll have to replace them next time...

George said:

Terry, ya need the flexy-shaft D-shaped tip special tool to reach and adjust the low-speed jets. PITA, but it can be done. Some have made their own using a short piece of brass tubing flattened on one side. Don't know what they used for the flex shaft.

Is the special tool a Honda item or is it generic? If it is a Honda item does anyone have the part number? If generic, who makes it and where can it be obtained? And does anyone have any pictures of the home made variety and instructions on how to fabricate one?

This is a great thread and very timely in my circumstance. I am on the verge of pulling the carbs so I can replace coolant hoses and I have been experiencing some carb issues myself. When I first start the bike the idle speed will drop to about 800 - 900 rpm without the choke on just a bit until after I have ridden a while. Then everything is normal without the use of the choke. I have run some Sea Foam through the tank and some Techron which has helped some in that the idle doesnt drop as much as it used to when this issue first presented itself but things still arent quite right. I sure wish I could make the Carb STOC.

I ordered the parts today gaskets for the air cleaner housing, carb insulators, some screws. David put up a good point, any ideas of what kind of carb cleaners I need to have? George, I have enough coffee however I don't have breakfast blend, I have the classic roast will that be fine? Just tell me, I can stop by Costco and get some.

Classic Roast is fine, Jay.

I'll carry WD-40 (pretty good cleaner) and Acetone (harsh but effective) and a tube of Plumbers Grease. Pick up a can of Techron or Sea Foam to add for the after-work test ride.

I'll be amazed if the new carb insulators arrive in time.

I actually cleaned the carbs with one of my Marines with me. I found the culprit, all four jets are clogged up, a few dirt from the bowl, aside from that everything else is fine. Now my problem is the carb insulators, I just ordered them today, I haven't really looked at the old ones yet, from my quick glance I don't see any tear. I might just clean them up and use them to see if it solves my problem. Or I can just continue with the other projects, drain the coolant change the oil and filter.

Definitely do the fluid, filter changes... don't forget the brake (front and rear) and clutch!
George's suggestion of seafoam is good as it will clean varnish off the internals; so, you'll want to run a a tank with it in through the system.

Lots of great info in this thread. I do wish it had pics to go along with the info.

I'll take pics on Saturday.

I bought the fluids and filter today. I will be running just an ordinary oil then after a couple of thousand miles I am thinking of using AMSOIL, I have to go get my preferred customer back first. I have the pics just too lazy to put it up, I'll try tonight.

Thanks George, wish I could be there. Jaysponger thank you for sharing your pics.

Jay, you can open the album, copy address, then post in a message as a link (world/paper clip symbol above.)

Or, you can open a picture in the album, right click on it and click the "copy image location" text, then click on the postcard above and <control>V

This is prior to getting out the carbs, notice my nice shirt covering up the intake. That's very thorough right there....LOL. And if you notice those little brown pieces on top of the engine, those are some of the "broomstick" pieces. Oh, yeah those are Honda's in the garage, my Chevy is outside. You gotta have priorities...

Thanks George, as always very helpful. The insulators does not look bad, I might just use it and keep what I ordered as spare for later breakdown.

Jay, the pics don't show here. Might be a size issue, I think 800x600 is the biggest you can attach.

Was gonna suggest you keep those new boots for when ya do the coolant hoses. With a hair dryer and plumber's grease we'll get yur carbs back on the old ones.

I can actually see the pictures hmmm...I wonder whats wrong. I am kinda embarassed i am the young'un and i am computer illiterate.
