Hey folks,.........my son was riding our 96' CR125 when it set up on him. Radiators leaked so I'm assuming he let it run low on coolant. I've got the engine out of the bike and want to know what a typical top end rebuild would cost....

What do you mean by "my son was riding our 96' CR125 when it set up on him."?

Haha, I had to re-read that like 5 times before I knew it didn't make any sense.

After a seizure due to overheating? Could be 500 bucks, depends on how trashed the cylinder is. Make sure you check the bottom end out very well while it's apart. I'd suggest getting the coolant leak fixed too..... :think:

Find out a complete top and bottom end kit. Probably less than $350 for it. They come complete with gaskets, bearings, seals, piston, crank etc.

ONly thing not included is the cylinder like mentioned.

Try pulling it off. The part that sounds locked up is the crank. The jug should still pull right off. Theres no reason for it to be stuck. This is not going to be cheap. Remember Ebay is your friend. I just bout a 96 that needed a top end. I got everything to do it for well under $100 including a used low hour cylinder. So I had money to buy all new plastics! The bottom end is what will kick your ass.

I have had some really bad locked up motors. If the ring is really hung up you may have to tap it out with a big punch and a hammer.
