caleb_yfz350 Posted June 17, 2006 Report Posted June 17, 2006 when should i rebuild my engine and how hard is it to do? when you blow it, or when you've tried everything else and have no other choice, or when you want to modify it. its fairly hard to do if your not use to working with engines Quote
watkins Posted June 17, 2006 Report Posted June 17, 2006 (edited) Well.. like stated already when it blows, but also do compression checks periodically and you want both cylinders within 10% of eachother... or when your compression is pretty low its time for a rebuild.. you may be able to get away with just rings if your cylinders & pistons are in good shape. And a top end job is a piece of cake to do.. if you have never done it before then just make sure you have your clymers manual in hand... but it isnt rocket science.

You run a big risk of crapping out your crank, bearings, whatever gear it was in when it locked up.....you get the picture. Get a compression tester, keep an eye on your jetting, a clymers will give you all the specifics as far as ring end gap, and when to inspect top end according to compression and such. A lot of time you can get away with a hone and a new set of rings if you just rebuild it when it is supposed to be, at very least, save on a new crank. Quote
