probably the easiest is to put a board between the rim and swingarm... and yes counter clockwise =off... make sure that the brass washer is FLAT!!!! all the way around the nut... and yes you can use an impact to take it off.

Thats a MUST.

Make damn sure its in neutral. I've seen tranny gears broken more than once from using the tranny and engine to hold the output shaft from turning while using an impact.
In neutral and with a block of wood in the wheel works well with an impact gun.

Hey, just a question...

What is the point of putting a block of wood in the wheel if the bike is in neutral?

I used a block of wood, with the bike in 1st, and a breaker bar...is that dangerous?

I can't imagine that my arm loads the trans more than 175 hp does...

i do not think it is dangerous if you apply constant pressure, I would not use an impact with it in gear... but if you are using a breaker bar. I would think it would be ok...

exactly.
I hit mine this morning with my impact. It had a loose chain and I didn't even bend back the lockwasher. Buzzed it right off.

Torquing it back on is another story...

I actuall just buzz it back on with the impact. I think some things just arent that critical and dont require the torque wrench to be brought out. heard a few horror stories of people using a torque wrench, like a ZRX dude who torqued his oil drain plug on in ft-lbs instead if in-lbs, can you say stripped. LOL

I used that method the first time I changed my front sprocket. The bike was on the rear stand at the time. I had to pull HARD on the breaker bar. When I got it to break free, the rear stand shifted and the bike fell on me.

Now I use the impact method with the bike on the ground.
