I have read through alot of the psot here and it seems like you guys know what your talking about so I hope you cna help me with this one. i got a tak 88 kit with bbr pipe, stock head. I just put that inner rotor kit on from Kitaco and it kicked over fine. When i ride it, it runs like crap from about three quarter to full throttle. I know that the timing is already advanced 10* and you can move the magnet to 20*, but that will be to much, so I am right in the middle. I tried everything with the timing and still runs bad. I then thought it was a jetting problem. Before I had a 85 main and I run that ultimate 4 race gas, it was running abit lean, but not much, just back fired every once in a while. I put a 92 main in and the bike still runs like crap, is there anything else I should try. I agree that the bike revs awesome, but when i go to ride it it jerks and bogs, help please!!
