And put the gears in neutral, you don't want to break anything.

definately either an impact gun or a breaker bar with a hammer. CRFthumper has it correct. :thumbsup:

I had a tough time getting mine off of my WR this winter. Impact would not break it loose. I finally got it off with a bf pair of channel locks and a breaker bar.

Forget trying to hold the brake or put it in gear... I put a hammer handle through the spokes on top of the swingarm. Put it right up against the nipples. There is no way on earth you will be able to generate enough force to do any damage. Works every time. Repeat for installation, but this time under the swingarm... obviously.

Note: Assuming you still have the chain on.

When doing work like this I was taught by the old schoolers. I work by myself so no ones around to hold my brake. Take a piece of 3/8 soft nylon rope and tie a knot in it at the end. Remove your spark plug and slide the knot into the cylinder and carefully raise the piston till it stops. Take the sprocket off or the flywheel what ever your doing and then to tighten back up reverse the process. I'm curious as to what you think about this method, so do tell.
