If you lathe one piston, it will be out of balance from the other. More stress on the crank. You can get a piston for $65. How long has it been since a top end rebuild anyway. That piston may work fine.. I just don't do things that way. I bet it would work... but is it worth it to find out !!!
i was only thinking on using emery on fine grit sandpaper on the piston and dome to 'clean it up' rather than using tooling and taking off material. the top end is less then 3 minutes old.
From what I'm seeing you lost a bearing or a ring caught and busted up.
all the rings are intact on both sides
What made you take the motor apart. That would in deciding what's going on.
i did my first plug chop on the fresh rebuild and saw the metal so i pulled the head to check it out. when i saw the piston top i pulled the jug to check the walls and rings. then i saw the shit in the bottom and pulled the motor out.
As far a rebuilding the crank. What are you going for? Do you want it to run just like it is or are you looking for more performance?
i just want my shit to run, no need to go stroker...i just bought this crank 20 hours ago
T.D.R does good crank rebuilds. Send them yours and they'll send you a rebuilt one. I think it's $350 -$400. Or, find a shop that will rebuild them. Some charge $120 plus parts.
do you know the shops names that will rebuild mine for $120 + ?
Lots of options here. Let us know why you took it apart... was the motor locked or what.
it never locked up. i think i shut it off before anything bad happened.
On the clutch basket, make sure the kick starte gear still has the e clip on it. I had it come off before. I went to the hardware store and bought a little smaller one that has worked out great. I'm not sure if that's your trouble... it's just something that comes to mind.
thanks, i'll check that out.
