Fuel Pressure Regulator Upgrades?

[emshaferii]

I was curious how many folks have done the Turbo City FPR upgrade and their level of satisfaction with the LOE and cost for the item.

[Serk]

Missing option - Bike came with the farkle already on it... :)

I will be curious to see what people say about it though...

[eddiemack]

MPG increased by 1 or 2. Bike now seems to get up and go. Great investment, fairly easy to install.

[mather3]

Was easy to install. The ride is much smoother. Money well spent.

[Ken]

Voted for #4 - not sure there was a drastic difference, but very effective, noticeable, and did smooth out the throttle a bit. Would do it all over again if I traded up to a later year.

[chazs_peanut]

For me, it was an "OMG, what a difference!" It made the bike (and curves) incredibly smooth. Thanks to this forum for introducing me to it! :bow1:

All of the replies and opinions I've read about the FPR are, well, opinions and I need something a little more concrete before I make up my mind.

Fred..
Going to be tuff to do if you are looking for hard stats..etc..

Opinions may be all you have to go on. The majority of people who have swapped it have been happy..including me.

For me, I am not that in tune with my biek regarding flat spots however one thing I really notices was the much smoother throttle. Jerkiness is pretty much gone. (especailly coming off throttle)..That is really hard to measure.

Install time is only 30 minutes or so and it is cheap enough to say you don;t have much too lose. However if you have no complaints in the areas where people say that the FPR fixed something, then don't change anything.

I'm old-school hot-rod. Anytime I can increase airflow (K&N Filter) and fuel flow (FPR) into my engine, I'll do it!

Kempo-STer, you are probably right. And, like you, I am not that "in tune" with my bike. I don't notice any flat spots in the power but I do notice crappy throttle response at slow speeds. I have learned to work around it and, yes, I've taken as much slack out of the cable as I can. However, I've not worked at the cable from the other end.

I may try out the FPR simply due to the sheer volume of positive responses - after I pay for my last vacation.

Thanks for the input...:)

Install is pretty simple and if I had another ST I would certainly do it again.
That's the bottom line ;)

I plan to order and install one on my 05' ASAP. I love the bike except for the low speed response.

In a word: SMOOTH

[pala4evr]

hey tom,
put one up on ebay and lets see what its really worth,:bow1:

[elkhntingfool]

I installed one this Saturday at the Tech day in Turbo Tom's shop. It does everything that is claimed. My wife and I just got back from a 200 mile ride this afternoon and even SHE noticed a huge difference in the smoothness of the bike. I now have a throttle instead of a fuel on/off switch.

Buy one, you'll like it

This is one area Honda knows there is a weakness and they look the other way. I called the local dealer and asked about the fuel regulator problem. He acted like he had never heard a about it. Give me a break. I chanded to a Turbo City FPA and it makes the bike much smoother for two up riding.

[ST1300 Alicia]

I have no doubt that it improves the performance and drive-ability of the bike. It may also improve fuel mileage some. But what does it do to emissions. I know, we really aren't that concerned with emissions and they don't smog check bikes. At least not yet anyway. When a manufacturer produces a product to meet 2008 smog rules their will be some drive-ability concerns. In order for the Fed's to be happy it has to run to lean. It has to run TOO LEAN. I am sure Honda is aware of the drive-ability issues. If they were to fatten the mixture up just a little bit, it probably would not meet CARB 2008 standards. The Auto Manufacturers have been up against this for years. I know because I was a Master Technician with Toyota for many years and we had our share of drive-ability issues. I will probably add a FPR to my bike also. However we might need to be a little more kind to Honda as they might just be doing the best they can. In the future we will have five or six catalytic converters and all of the junk you have under the hood of your car. Until then maybe we need to realize that Honda is probably doing the best they can and we will cheat a little to regain drive-ability.

I rode with the stock set up locally in upstate NY for a few months and did not have any issues with the bike. Went down for a weekend of riding in the mountains of West VA and discovered the infamous flat spot when rolling on the power at a more brisk pace than our local roads afford. The stock flat spot coupled with the natural slight driveline lash of a shaftie prompted me to order the Turbo Tom part as soon as I got home.

No pressing need to install it for the riding I do around here which is on straight and boring roads. However it will hopefully cure what ails the bike when the roads turn twisty and the pace can quicken.

[mayner]

I'm putting mine in tomorrow (Sat) if I don't go on a ride that may be cancelled. If the ride happens I'll put it on the bike Sunday. I know the stated benefits but I have seen only a few talk about changes in fuel mileage.

Are there any? Does the lower idle make-up for any (possible) mileage losses due to higher pressure?

[AzDesertRider]

Had no real complaints with rideability before, but the TT FPR really did make the bike much more enjoyable to ride. :03biker: The difference, although not huge in any one area, is noticeable immediately. :bow1: Thanks Tom! I did not think that I could like my ST even more... but I do!

[sherob]

I didn't notice flat spots before... what I have noticed since putting it on; low end grunt factor increased, throttle switch is gone, has more zoom factor in lower gears... really noticed it in TN when doing some sweet twisty backroads, was able to leave her in 3rd and drop down in low speeds without shuddering and throttle her backup :p:

[maldos]

Installed mine at Tom's shop. Ride home was smoother but really noticed the change the next day whild doing the Ortega Hwy Twisties. Thanks Tom

[Fastraveller]

I purchased the FPR almost immediately after I bought the bike and installed it myself. I have stock air cleaner and exhaust. I noticed a subtle improvement in low-end response up to approximately 2700 rpm. Take off from start required less clutch fanning and revving of the engine, even with a passenger. I believe there was also an improvement when shifting into second gear. I want to repeat, this was a subtle improvement. I believe the engine generally ran a bit smoother as well. I think my main improvement was an increase in gas milage since I consistently get better gas milage than someone else I ride with that has not done the FPR mod (we have similar riding styles, same year ST's, etc).

Would I do it again? Yeah sure, but I don't think someone should expect a considerable horsepower-per-dollar type of improvement. My reward primarily came from installing it myself (it really isn't that hard) and getting to know my bike better.

[emshaferii]

Anyone able to clear up what it means to do the throttle starter valve sync mentioned in steps 14 to 19 on the install instructions for the FPR? That is the only part of the install that is not clear to me. thanks

[LBD]

I installed the fpr and the air cleaner from Turbo City. I can't believe the 30 minutes install time-it took me 2 hours of careful and slow work-had some trouble getting the tank to settle in the maintenance slot-kept trying to slide forward. Almost lost one of the spring clips as it slid down the hose and out of site. I did the 59 psi version. I felt the improvement right away, especially off idle-more immediate zip without clutch slip. Tried to take off at low revs in high gear and it's much smoother and more willing now than before. I never felt the flat spot before, so can't comment on that. Highly recommended-just watch the small parts!

[Finewest]

Can/does Tom install it at his shop?

[Ken]

He hosted a Tech Event recently and it was well attended. Not sure if there is another one planned. But Tom is very customer oriented -- why not give him a call?

[CaST]

I was curious how many folks have done the Turbo City FPR upgrade and their level of satisfaction with the LOE and cost for the item.

I remember my first impression after installing as to why it doesn't come stock that way. I have had several moments like that with this motorcycle but now I am too far into it to go back now.

I saw a drastic improvement. Its a must along with the seat, risers, power outlet, Hwy Wings and a top box.

[MLRickards]

Not being overly mechanically inclined, I bought the extended warranty for my '05 ST1300. Anybody know whether adding something like the FPR invalidates that warranty?

[Marq]

Just installed mine last weekend and from the time I started it up there was a difference. Low RPM throttle response is better and the anoying bog, technical term, is gone. Only problem I had is 1 of the funnel base screws could not be removed, no impact screw driver, and I had to replace one base and a2 screws. Next up is counter balance lash adjustment.

[JellyRoll]

If you couldn't get the funnel base screw out, how did you do it? Did you lose the other two?

I'm getting mine today and want every tool made to help me do the mod without stress. Got two magnetic screwdrivers and already have an impact driver but it's only got a flat blade on it.

[Marq]

As the instructions state removing the 8 funnel base screws is the tough part. I got 7 out with little effort, would recommend a nice new screw driver that you can get a good grip on. Number 8 wouldnt budge. Looking closely at the funnel base the plastic is very thin so I simply pulled/broke it off and got a pair of vice grips on the screw and out it came. Hated to do it but by then the screw head was stripped and in the end the part was $5 plus one screw $2.

Thanks for that info. I got mine yesterday and went to Sears the day before. I have every tool they make, including impact driver....hahahahaa, should be cake. They have these screw removers that dig in and supposedly back out a bad one. Wonder if that would have worked.

[RAM]

Installed and loving it! Highly recommend this upgrade.

[emshaferii]

Installed FPR last night....made already smooth bike even smoother.....hit 57 MPG on my 1 AM drive in the "cool".....this was easier to install than my Heli bars that's for sure....not sure why it suggests an impact driver though.....everything uninstalled and installed exactly as the directions said......minimal gas leakage......DIY, no problem!!!!

[AZST]

Love my FPR.

I had trouble with just 2 screws....which I needed the impact driver for.

Increases the enjoyability of the ST for around 100 bucks.

I finished the install this evening. It was an easy job, except for spring clamps!! damn yokes! I didnt require an impact driver, just a good screwdriver.
The problems I had before was that the bike was a little jerky, particularly when going slow. This could be delt with by slipping the clutch so not a huge problem for me. Also when driving on bumpy roads (which we have a lot of in Ireland) the engine would sound jerky due to slight movement of your hand. I done my best with this problem before, by holding the hand grip as light as I could, a little clutch (which I dont like to do when travelling at 60mph) but I couldnt get around the problem. This is now gone as far as I can see. The throttle is now much smoother.
This is a job well worth doing to your bike. Especially if u ride on any bad roads or do a lot of slow riding in towns etc.
