Ebay has piston , ring and gasket kits for about $30. The barrel is cast iron, so if there is no lip a simple hone may do.
I f the barrel is pitted , you will need an oversize piston kit, and a machine shop to bore the barrel to a bigger size.

04 Chrysler Concorde wnt start I changd the battery it wrked for 2 days nw won't start was coming off the I car started to over heat now wn't crank took it to shop they say I ned a new motor


If it overheated and won't crank it means that the motor is ceased and would need a complete strip and rebuild if possible depends on damage caused and costs
may be cheaper to fit a used motor and get someone to look at the ceased motor for a quote on a rebuild
most important thing is to find out why it was overheating

JUST BOUGHT A 2004 DT125R IT HASNT BEEN STARTED FROM 2006 BIKE WAS LEFT UNDER A COVER OUTSIDE BITS OF SURFACE RUST THAT BOUT IT STEERING LOCK CEASED IS THIS BIKE STILL ANY GOOD


Surface rust will come off without leaving weak framework. The engine will, if not rotted out, refurbish so as a rule, it is probably worth rescuing.
A Yamaha DT125R hopeful owner will be pleased to own it. The engine may be OK after lubrication and a little TLC.
