motor problems

[88dunerider]

so my piston shot a couple weeks ago due to an air leak , got it bored out new piston and today got everything back together and go to fire it up and it doesnt want to kick over no budge at all !!! any suggestions on what to do?? i know it could be alum in the crank but anything else?

gonna have to tear it back down. might have siezed, snagged a ring, bad bearing, etc...

prolly put the piston in backwards.

so the piston in not in backwards . the connecting rod seems to be jammed in the crankshaft and that is why it doesnt want to kick over , there is some dis coloration where the connecting rod connects to the crank , what do you guys think do i need the whole new crankshaft or just the connecting rod???

new rod and bearing.... looks like you almost seized a crank bearing

your gunna have to split the cases and replace crank and bearings. the crank can be rebuilt to be as good as new. do a search. there are several places to get it done and at a reasonable cost.

i think im just goin to go with the whole new crank and connecting rod , looks like hot rod makes the whole thing and im just going to have the local atv shop put it in hopefully get her runnin by next week .

thats fine en goed but make sure that the guy at the shop checks the trueness of the new crank before install and doesnt arbitrarily stick it in the engine. :cool:
