Ok, well I've had my RC(SP1) for about a month and its been having a strange problem. When you're in neutral, the bike rev's perfectly. When you accelerate slowly it revs fine through all the gears. But when you go to get on it, it will buck at around 3-4k rpms, until you let off and accelerate slower. I have the pair and flapper mod done, Yoshi slips, and the 600rr coil convesion.
At first i thought the problem was my TPS/MAP sensor since it was throwing codes, so i replaced them with SP2 throttle bodies, injectors, and airbox and modified an sp2 map onto my PCii. The FI code went away, but the bucking is still there. I also changed my battery just in case it was a voltage problem.
Any help would be appreciated. Could it really be a tune issue??? Its not throwing a code anymore, but the problem is really irritating.
