i usually when dealing with one that is a pain is, i put it in gear and also put a soft wood 2x4 through the rim and turn till two by four locks the rim to swingarm, then i use a strong impact wrench.... then upon re install i9 use regular socket then a torque wrench to proper specs.

Not if you're using the board.

Sucessful mission, new chains on plus sprockets.. riveting went well the Rk tool worked great didnt even need to grind off the heads. Just need to re-torque the drive nut, my 3/8s torque wrench doesnt go to 61lbs so gotta borrow my buddys 1/2 wrench. When I get my digi camera ill post some picks.

Im torqueing the front drive nut now.. and wondering since I didnt buy the new nut (on the 07 the lock washer is attached to the nut) should I locktite it or just go more then the spec of 61ft-lbs.

You don't need to pick up another drive nut. Just use a drop or two of Loctite Blue and torque to spec and you'll be ok.
