Hey everyone. I was just wondering if there is better jetting then stock if u remove the exhaust baffel, take off the airbox lid, and cut the gray wire. Thats all. All answers are welcom and apreciated. Thanks. (a 13 year old shouldn't really want more power from a 426...but what the hell): ) Oh yea and i ride from 0-1000 feet elevation in new england weather.

I have found the #48pj,#100paj combo to be way too rich at idle to1/4 throttle.I'm back to #42pj,#75paj. TheOBELN needle fattens it up quite a bit low to mid. I run a#175 main,pas at 1 to1+1/4 depending on time of year(temp). After you get enough fuel into it so it runs strong,you will want to look at the B.K. mod- there is just too much accelerator pump duration for a well jetted bike.

Yes, I forgot to mention I did the BK mod.
