ok i usually try to stat as far away from polaris quads as possible but i ended up working on one for a friend of mine. it's a 400 xpress it's a 2 stroke 400cc it dropped a piston skirt so instead of having me rebuiold the engine he's gonna get a used engine and i'm gonna put it in. well i started taking to engine out and ran into a problem. how in the hell do you get the drive pulley off the crank. i have to get this thing off to take the plate off for the last motor mount. this is driving me nuts. if anybody can help it would be really great.
