[QUOTE="destructo, post: 1298492, member: 67385"] Its like rmc olderthandirt said, you can regear, go taller with the front sprocket a tooth or its really nice when you have a six speed two stroke, absolute heaven for me both my KDX 220 and my KX 125 are six speed, alot faster on top, nice crisp jetting, when you let off the throttle on a hard topend run with a 2 stroke you should really pull the clutch in and gently rev the motor until backed down to the desired speed and gear, because the cylinder gets hot and the fuel keeps your cylinder temps down. Your piston gets alot hotter than your cylinder, the cylinder has water jackets all around it so it won't expand as much or as fast as your piston, and ultimately your piston could seize, that is one of the reasons I run forged pistons they don't expand as much because they are about 10 times as hard as a cast aluminum piston. I also run a little more oil in my premix, I use 32:1 premix which will also alow for a little harder faster riding. The oil in your premix is all the lubrication your piston, rings, cylinder and crank will recieve, the four stroke oil in your gearcase never touches your crank and crank bearings, so I feel it is detromental to your motors health to run a little higher oil premix. I absolutely love the way a properly jetted 2 stroke feels on topend, has an old school hot rod feel to it, hope this helps. :cool: [/QUOTE]
