Was wondering if any of you with a piped/geared Gen I Busa have done any 2nd gear to 4-5th gear roll-ons against any stk Gen II Busa's? If so, how did you fare?
I recently purchased a 03 with 26K miles on it. Was in pretty good shape but needed a few little things. Did'nt run worth a hoot down low when i got it. Found the intake valves on the center two cyls had no lash at all. Got those adjusted and the bike seems to run well. It had stk gearing so i dropped a tooth on the front sprocket. It has a brock Street meg exhaust and PCIIIR with correct map from Brock. The center two tubes on the header have been dented close to 1/2 closed, which i'm sure is hampering performance some though Brock says that dents under 1/2" do not hamper performance. Mine i believe are over 1/2".
Anyway, just running the bike through its paces down the road alone makes it hard to tell how my bike is running as compared to what a known good running bike should. Seems ok but i've been surprised before...
Met up with a co-worker that has a stone stk Gen II. Its been lowered and he has removed the cans(can't afford an exhaust and likes it louder...). Other than that its stone stk. It is a known good running bike as i've run it down the track a few times and it pulls the mph it should with me on it.
Maybe i'm expecting too much from a good running Gen I, but i was figuring that one setup like mine should keep up with a stk Gen II if it was running well. The pipe/PC and small airbox mod "should" put a good running Gen I around 170hp to the wheel. Stk Gen II's knock down around 170-175 give or take if i understand right(?). I figure gearing should help a good bit as well.
Well, i got a good look at his tail light...but it was not that bad. From the initial hit i jumped out on him 1 1/2 bike lengths(i mean immediatly) and it was the top of 4th gear before he came by me and by the middle of 5th gear he put a bike and 1/2 on me. I'm not sure if he is being super aggressive with the initial hit but he assured me he was. I even waited to watch his nose raise up before i pinned my throttle but the outcome was the same(i jumped out on him).
I'm not dissappointed at all. My airbox does not seal well at all to the frame(foam missing and such) and my air filter needs replacing so there "may" be slight gains by addressing these. Then there is the exhaust issue. I know the dents are hurting performance some, but how much i'm not sure. This will be addressed as soon as i can afford to.
BTW, we both weigh close to the same.
So...has anyone else done some roll-ons simmilarly setup? What was the outcome? Just curious.
