I tried putting the trans in 5th gear and jamming a small wrench in the back sprocket, but still couldn't manage to break the nut loose. I'm trying to do this with the bike on its side so I don't have to drain the oil, so holding the rear brake isn't an option (yet). Any suggestions from the experts out here?

Hold the engine by putting it in 5th and running a hammer handle across the swing arm, through the spokes, near the rim.

Too easy. Besides, I was assuming he doesn't have one, or he would have used it already.

I have an impact, but it would be more trouble than it's worth right now to dig my compressor out to use it. I'll try the hammer trick, thanks gray :thumbsup:

To get the nut off put the hammer on the top side of the swingarm, to torque it back down put it on the bottom side :thumbsup:
BTW grayracer I owe you a beer, it worked like a charm :worthy:

No, you will still need a puller. They were just talking about getting the nut loose.

The puller is the same as that for a CRF450, BTW.

Thanks for the great post. Just ordered my puller.

One more question: Is the nut RH thread or LH thread. Hate to go after it with the impact wrench set the worng way!!!!!!!!!!!

Another trick for locking the motor up is lowering a length of rope through the spark plug hole, so the piston comes up against it. I did this on my YZ250 when I installed a flywheel weight, worked awesome!

I just purchased one from my dealer, the price came up as like $35, they said that can't be, so they sold it to me for $10.95. (the same price as the others):applause:

I'm "almost" sure it is a left hand thread.

That could be why he can't break it loose.
