After 14 years of owning my S1W I'm still doing the odd bit of stuff to it to perfect it, but realise it's been a very long time since I did anything to up its performance. That is to say I am happy with what I have now. 100 or so RWHP. There was a time a few years ago I wanted more, but there really is no point wanting more now as what I have suits everything about the bike and how I enjoy it. So what about other Buellers I was thinking. It seems a long time since I saw a thread on BadWeB about anyone looking to tune their air cooled Buell for more power and performance. Does old skool Buell tuning still exist, and if so what is current for you in your pursuit of more power? Any graphs to show too? Once upon a time BadWeB was alive with this stuff. Be nice to know it still goes on. Rocket in England | ||

Just keeping it running's enough mate. | ||

I think if you can keep it running well with this crap gas we have you're a happy camper! Now my Harley is a never ending story!!  | ||

rocket - what do you have done to yours to get 100whp? | ||

Yea, I was thinking the same thing | ||
| Teeps |
No. Been using a stock '07 tune with square idle mod for over 3 years. | ||

I still tune, as I make changes, and could always use good advice. I haven't dyno'd my Cyclone, yet, but re-jetted, and have changed mufflers, from stock to a Wileyco Ti slip on and back to stock.... because I lived in a quiet residential 'hood and was getting home at midnight. The noise factor didn't bother me any other time, but doing 30 in a twisty development gave me a gear choice of 2 wonderfully resonate notes, tom toms on Ritalin, or trolls pounding on castle door. Both of which I like, mind you, but being a good neighbor and all...... But now I'm in the boonies, and I can't possibly be as irritating as the hog 3 houses down, or the 4 wheelers at 3am across the street. Besides, it's a 55mph road right past the driveway, so it's actually minimum noise coming and going. And while I've always mocked the "loud pipes save lives" mantra, I live in such thick deer country that if I don't see one on a ride I assume I missed him. So the Wileyco is going back on and I have to re tune to make it proper. Other than exhaust or intake changes, that sort of thing, I sort of assumed that most tube frame guys have already tuned their carbs. But now that I say that, I realize I'm probably wrong.... I basically paid attention to what this web site told me, since I wasn't used to Keihin CV's. Looked in the tech section of Badweb, and just did what I've been doing for decades with mikuni's and jetted it as lean as I felt comfortable without an air fuel gauge, or, a bit rich. http://www.nightrider.com/biketech/hd_cv_mods.htm Any suggestions on best air fuel gauge for tuning? | ||

to answer your question: sort of had my bike tuned with ECMspy 90hp/90tq at wheel | ||
| Sifo |
I tuned my XB with ECMspy many miles ago. Very happy with how it runs, 92hp/77tq at the wheel. I haven't felt the need to do more modifications. | ||

i have to do some engine work to mine first then i plan on working on a tune for it. | ||

lol - a whole world of Blastards are tuning! EZ | ||

rocket - what do you have done to yours to get 100whp? Oh mine's very dated now as it's not been changed since I first tuned it back in about 1999. After it threw a rod I rebuilt it the same way exactly in the mid 2000's and it's still that way now. S&S bevel edged crank. S&S rods. Wiseco forged pistons. American Air Cooled Cylinders. Andrews N9's. Taperlite adj pushrods. Dick O'Brien gas flowed TS heads. Heavy duty valve springs. Mikuni HSR42. Forcewinder intake with larger K&N filter. Race Kit pipe and muffler. Crane HI4E single fire. Accel 8.8mm wires. Still a fooking beast of a Buell! Rocket in England | ||

  Man, if/when the day comes that I can acquire a tuber Buell, I will plumb in an Aerocharger as best I can. Jonesing for an S3T. | ||

Mine's pulling 100hp and 90ft-lbs. I reckon with a proper dyno tune it'd probably be closer to 110hp, but I don't have the cash or connections to do so these days. The current jetting, advance, and timing settings were done seat of the pants. Mine has been that way for years as well. It currently needs a set of lifters as one failed earlier this year, and the others are getting loud. The current set-up is exactly as I like it. I agree on the gas comment. I need to use octane booster to get the most of it these days, where I could've sworn that was unnecessary pre-ethanol. | ||

In my (expensive) experience much more than 100rwbhp leads to expensive rebuilds and shorted engine life. You have to remember that we are talking about aged H-D lumps that normally put out around 48bhp, so even 100bhp is a serious increase. I knew a race team that had a tube frame race bike with 130bhp a few years ago. That engine had a life of around 90 minutes between major overhauls! I used to build our Xb racers to give around 100-105 bhp at the rear wheel, which gave excellent reliability even if at the expense of a little power compared to the people we were racing against sometimes. In Thunderbike competition this was enough to be competitive though, in combination with nice flat torque curve and some weight loss  | ||

Rocket, What went wrong to make your motor spit a rod and why did you use the same rod the second time. Let's see some pics. | ||

Being new to the Buell world (owned my 2000 S3T for just over a year and 15k miles), I am just now starting to plan out a tune for this bike. I am in the process of doing the XB rocker box mod and once that is done. my indy will be helping me dial the engine in on their Dyno with ECM spy. My hope is to get it _close_ to my sportsters performance (95 with 89" Stroker kit) and get better gas mileage. I have been perusing this site and others in hopes of learning more about ECM spy and the tune process, specifically for my bike. I am going to get almost free time on the dyno in exchange for teaching his tech about ECM spy and the tune process (my Buell is the only one they have had in their shop in many many years). | ||

In my (expensive) experience much more than 100rwbhp leads to expensive rebuilds and shorted engine life. Without experience other than my own Buell, I'd tend to agree. An increase in capacity with a big bore kit might be the only exception I could think of, but I'd want big bore on good foundations and not a stock motor otherwise. Rocket in England | ||

What went wrong to make your motor spit a rod and why did you use the same rod the second time. Oh my, what a can of worms, lol. The short version is, the HD dealer carried out warranty work on the heads, at which point I asked that they put Cometic head and base gaskets on. To do so the technician removed the Wiseco pistons, then put them back on, it turns out using new HD circlips. These clips are 1mm and not 1.6mm like Wiseco ones. Over a thousand miles later the gudgeon pin spread the circlip into the piston. The gudgeon pin moved across the piston. As it did so, the side it moved away from was weakened and scooped out like a cone until it was just enough for the forces that be to allow the gudgeon pin to bend the top of the rid over enough it snapped off. The rod punched its way through the case under the starter and down again and up between the cylinders. Let's see some pics.   Rocket in England | ||

 I had this cylinder repaired and it's still working perfectly well today, several years and several thousand miles later! Rocket in England | ||

Holy expensive simple mistake batman! | ||

Woops. Funny, just this morning a young person was driving a three cylinder car through the neighborhood on two cylinders. A con rod could clearly be heard slapping the cylinder around. That sound is unmistakable. | ||

No, I don't own one anymore Thanks to the Bush Regime. |
