The Rev 3 200 is soft also the 250,should have tried a 270 bit sharper than the 250. if possible,machine the flywheel will make it pick up a lot quicker depending how much you take off,go too far and suffer no bottom end grunt.i once bought a sy250 because they were supposed to be docile.got it home went out to try it.Thought i was on a motorcross bike just a touch of throttle and it was off like a rocket.checked timing to see if it had been altered,but no.Happened to see a Scorpa 250 flywheel for sale on e bay.didn't look the same as my one.rechecked mine that's when i noticed it had been machined down.
