I'm currently changing sprockets and chain and cannot get the front sprocket nut loose to save my life! I have put electric impact on the nut and prolly over 200ft lbs of force and it won't budge! Also is the nut reverse thread or not, we've tried it each way and no movement. Any advice???

I'm pretty sure the nut is standard threads. A decent air impact gun should make quick work of it, just be sure the bike is in neutral and supported (you'll roll it right off the kick stand if not careful!) and pull the trigger (with the chain and rear wheel still in place of course).

If you are looking to buy an air impact gun the Ingerson Rand Ti 1/2" model is quite good (just over 1,000 ft/lbs IIRC).

Check in the file vault, Its on page 372 of the service manual. it's just standard threads, not reversed.
