I have a problem. I smashed my pipe a little while ago and i replaced it but since the it never hit the power band like it used to. It will like dog out at like 4500-5000 rpm. but if i rev it up it revs perfect it is just when i ride it. I changed the reeds but thata didn´t help. The pipe that i crushed look like somebody took it apart and took the bafflings out. actully i know they did because it was way lound but now with the new pipe on it is quite. It runs a little better if i take the whole air box off the carb. so i was wondering if maybe the jets are too big and it is not getting enough air for the amount of fuel it is getting at high rpms or something? i don´t know just somebody PLEASE HELP ME!!! Because i really like this bike! It is the best trail bike i have ever riden (except for suspension) and i would really like to take it out agian but i can´t until it runs right so HELP!!!
