tbolt

hi guys, i am looking for a little advice here... i currently have a gpx 125 in my bike and am hungry for more but i cant decide on the tb version of the gpx i currently have or a 155/160 ho... i love the way my engine revs but im just not convinced that the gpx 125 engine dhz sell with the tb...

hey guys, im thinking of turning my yx 150 (klx style) into a 170 and ive got a few questions. 1. has any of you guys bought the TB 170 kit and if you have, whats it like? 2. can i turn it into a stroker, with the works yx 160 short crank off TBoltusa? 3. if i can turn it into a stroker...
