how othen do you have to rebuild them ? are there any ways to tell when they are going to need a rebuild besides losing compression:confused:

you'll feel a power loss. and dont worry, their extremely cheap to rebuild and it takes less than 2 hours and you can do it yourself.

I think you should change them 2 times a year. Once every six months if you ride it alot. If you dont you can prolly get away with once a year. Some people change em' after every 3 races though:uhoh:
