375hp banshees Posted January 6, 2019 Author Report Share Posted January 6, 2019 I'd assume the old top end was different set up than current & he did a shotty job re assembling current... Now you have to decide how to go back together with it . but you'll have to find out what the 2 are , what's on the rods for #'s Quote Link to comment Share on other sites More sharing options...

Larry's Shee Posted January 7, 2019 Report Share Posted January 7, 2019 have never seen a wrist pin break. Pistons and pin bearings, yeah. If it was right side smoking you have bad crank seals. Wouldn't hurt to replace them anyways, peace of mind. Get yourself a Clymers repair manual. Look on side of cylinders for a number, Y1G or something like that. I wonder if you have junk chinese cylinders. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted January 7, 2019 Report Share Posted January 7, 2019 2gu, if I'm not mistaken.... and the piston on the left appears to be a lighter higher rpm piston. But do agree, need to push one pun into both pistons and check if the tops are the same height. have never seen a wrist pin break. Pistons and pin bearings, yeah.
