Hey whats up Everyone. Last week i went to El Mirage and when i opened it up and went full throttle in 6th gear it started sputtering. It didnt backfire real loud or die or anything but it was sputtering. Has this ever happened to anybody before?? Is this a jetting problem or something else. I had a GYTR PIPE and GYTR jet kit put in by a Yamaha dealer and I am running with the Airbox lid off with K&N w/ Outerwears. The receipt ssaid they installed a 22.5 Pilot and 55 Main. Everything else feels great on my Bike and definate notice in Powergain its just the Sputtering that i just noticed. Can somebody Please give my some advice. I still have the rest of the Jets if i need to change something. Is there a good sight with pics that will show me step by step how to rejet my 2005 Raptor 350 if this is the problem?? I suck at Mechanics and will definately need a step by step tuturial. Thanks Everyone! ~Raskal
