Brand new to this. Previous owner threw on a killer exhaust, which ran great with him on it. But I'm a little heavier and I was hoping to get a little more out of this engine, since otherwise it runs great and hasn't given me any problem turning over. Only issue I have is starting from a dead stop or working my way up hills. Hoping there's some kind of limiter I can drill out or shave off, fuel additive I could try, or really anything to give it a little more kick without breaking the bank. I appreciate all the information I was able to find already, and thanks in advance for keeping me on two wheels!!
