yes it is but it can be done with a longish (18") breaker bar or longer and socket to fit the nut. Remember to leave the tranny in neutral, roll the bike against a wall and hold the rear brake while you or someone else turns the nut loose.

"Remember to leave the tranny in neutral" Why in neutral...???

it is hard on the shift dogs to use the tranny as your "breaker bar". I leave mine in nuetral, roll it against a wall and then put a towel wrapped around a rod thru the rear wheel and use someone holding the rear break to get it to break loose.

Remember there is a security washer under the counter sprocket nut, you will have to bend it flat in order to break the nut loose.

It's not the easiest thing in the world, but it can be done. I couldn't wait for someone to help me so I tackled it myself. From the right side of the bike, I put one knee on the seat and used the other leg to hold the brake down. As I was doing this, I reached over and pulled up on the breaker bar. The first couple of times it wouldn't budge and I thought I would have to wait until I got the bike to my parent's garage and use my father's impact wrench. But then I tried flattening the lock washer some more all the way around the nut. I tried one more time and it came loose with a lot less force than I thought it would take. So like sneaky said, be sure and flatten the washer completely.

If you go to the "How To's" on this forum you'll find all the info you need, plus pictures. If you can't find it let me know. Good luck.

i think it's a 32 mm socket. i use a breaker bar and a rubber mallett. I hit the bar once and it came loose. I really thought it was going to be a pain, but it wasn't.

hate to beat a dead horse, but I'm doing my conversion tonight and can't get this damn sprocket off. I've used my impact, and broke two 2 inch shovel handles (used to hold the rear wheel).... I've tried everything known to man that I've got in my arsenal, can't bust the damn thing loose.

I've even tried clock-wise / counter-clockwise.....still won't budge. I know I'm putting the force down, I'm breaking 2" shovel handles..

I'm up for any ideas (even bad ones)..

a 3/4 inch to 1 inch breaker bar. someone hold the socket over the nut and you hit the breaker bar with a rubber mallett. it only took me three hits to losen it up. you do have the washer flaten out.

I had a bastard of a time doing mine too. Didn't get it done as fast as I wanted to.
The socket IS a 27mm. Same as rear axle!

My 1/2 in cheap air impact wouldn't do it.
I ended up using one of those electric impact guns. It took it about 6 wacks and it came loose. It worked very very well.

Don't forget to torque it to spec. I'm not positive without checking the book again, but I think it was 108ft lbs. Clean her up good while your in there.

Good Luck.

Also I put on a Vortex 16t. Wish I had stuck with Sprocket Specialists. Cheaper and qualitly looked as good if not better.

and it comes off "counter-clockwise" (opposite of clockwise) correct? lefty loosey? my 350ft lb impact wrench isn't cutting it, and neither is my 18" cheater bar.

Literally, I've got a guy sitting on the bike, all brakes on, and I'm spinning the rear wheel with my cheater bar. I'm putting some weight behind it...

I'm beginning to think its clockwise to loosen, I've tried a few times, but its not cutting it. my next phase is to burn the bitch off ...lol

Lefty loosey is correct...it's normal counter-clockwise..since you tried both ways it could be even tighter to break...smash that washer down as much as you can and use a breaker bar...start with the breaker bar toward near the ground and lift up..like a dead lift...it should break no problem from the help you described.

Well the simple little trick you may have missed.

HEAT

Take a little propane torch and heat the nut for a minute. If you plan to cut and or replace the back sprocket and or chain, just wedge a wrench in between the chain and rear sprocket to keep the wheel from moving. It may damage the sprocket....but if your replacing it, no biggie.

But heat and any impact gun should pull that nut no problem. Heat...and maybe some penetrating oil like WD (but not at the same time, that shit burns)

ok... fuck.... you're not gonna believe what I had to do to get the bitch off...

I was two-up, (one guy wasn't heavy enough)... then that kept the rear tire from spinning (even with the fuggin brake on).... the 3rd guy stepped on a 24" breaker bar and it gave... friggin finally!.... even my big-ass impact wouldn't pop that bitch off.

finally done, took 2 guys on the friggin bike to put enough weight on it to keep the tire in place.... crazy day.

ok, just for the record, I'm going 1 down in front, same 40 tooth in the rear. My AFAM front rear sprocket and 520 DID ERV chain weighs 3 POUNDS less than the OEM sprockets and 525 chain. I shit you not... that damn rear sprocket weighs 3 times what the new AFAM steel sprocket weighs...

3 POUNDS rotating mass.... thats like 75 hp! (lol, jk)... thats a TON!

I can't believe you guys. All you need to do is get a normal size pry bar wrap it generously with shop rags and wedge it across the rear wheel against the swingarm. It can be done without any help. Its that simple!!!
