[QUOTE="rosscopeeko, post: 1066727, member: 59382"] Thanks for all the good info guys. I'll forward this post to my friend. He was talking about how he heard boyesen makes an accelerator pump upgrade for the carb and that it might help his problems. His bike backfires on heavy load while climbing huge narly hills. It also sounds different from other 450's, like it might be missing a little at high rpm's. He's going to try running just straight premium 94 octane. He's also going to buy a jd jetting kit i think. When do you think he should check the valves? Thanks again for all the good info. [/QUOTE]
