I am rebuilding my motor out of 2015 sportsman 1000. not completely why it broke the crank. but it had a bent rod in the number 2 hole and key way was sheared off for the flywheel and started to mess with timing and cause pre ignition idk. started running weired under medium load then started knocking. but anyway got all new parts for bottom endand got all the specs i need from the service manual except for crank endplay. call local dealer they said they rebuild motors and asked them for a spec and they gave me 1/16 to1/8 of an inch of endplay with is massive. and i there is no thrust bearing ether witch i found quite odd. ive rebuilt many car motors and 4wheelers and this thing is its own bread in the bottom end. i have about .020 of end play right now it seems big from my experiance but first time in an xp motor. any one have any specs or anything i can go off.
