just picked up my first klx and plan on doing some more work. it currently has the tb 143, race head,and vm 26mm carb.i already need a bit more power as im 230 lbs. i plan on doing the tb 165,v2 and 28mm carb.6 disc clutch,forged shift star. im going to split the cases to do the 4th gear. my question is will the 08 output shaft be enuff or do i need a bbr or chp output? thinking about the stroker crank too but i want somethin that will be reliable and start easy too. dont know too much about the stroker crank or if its worth the trouble? i dont want the motor to rev like it has a 30lb piston in it.
