1. Riding with a 95 cr250 today we opened it up on a long straight (i have a 2000 yz250) And we accelertated at the same pace, until about 1/4 way through 5th gear, then he started pulling on me hard! WTF? Im 30 lbs lighter than him, plus my bike is lighter by a few. Both have the same gearing. Whats goin on here you think? The bike doesn't feel like it is opening way up when i give it more than 80% throttle or WOT. (it seems to change to a lower pitch when given WOT) Before i start doin a plug chop and mabye clean the carb/see what jets are in etc, what do these symptoms sound like so i have an idea of what im lookin for? Too lean or too rich up top? Could a silencer than needs to be repacked do this?
2. Also, when cruising at part throttle keeping a constant speed, the bike surges, not s smooth cruise. What do i need to adjust for this?
Thanks,
Nate
