How To Tune DOWN A 2 Stroke.. ?

[QUOTE="KTM Mike, post: 1323415, member: 22658"] With overly rich jetting you risk plenty of time for it to be tuned WAY down...all the time you spend swapping out fouled plugs. Better yet - be sure the jetting is RIGHT...often a bike jetting to rich down low will suddenly clear up when it come up off the rich pilot or needle setting and WHAM you now have power. Not good. Find out if the CR was set up with a multi taper needle - find out a good set up for a straight taper. Makes quite a difference on KTMS - dunno if it applys to a CR though. The flywheel weight comments are on the money though - makes much more controlable power. Another suggestion is a G2 throttle cam system - you can swap in more or less agressive cams as your skils improve - neat set up. Do go with a quiet silencer - not for power changes but just to keep it quiet. A side benefit MIGHT be a slight impact on power. Gearing it up (smaller rear sprocket or larger front) is a good suggestion as well. [/QUOTE]
