Well long story, i was at a race yesterday and the bike lost all its pull. got to the point a 125 could have probably beat it. It was fine for the first half a lap or so and then it slowly started getting worse and then finally on the 3rd lap it got to the point it would hardly accelerate in 2nd or 3rd gear and even backfired over a few jumps. The bike has 50 some hours on it and this is the only real problem i have ever had with it, other than a couple rides ago i checked the oil and it was overflowing so i changed it and haven't had the problem again. but I'm changing the injector (be here Thursday) cause I'm almost positive thats why it filled up. Do you guys think that the lack of power is also related to the injector, or is it possibly a weak fuel pump and/or clogged fuel filter? Thanks!
