Its easier than you think . Trust me .

Step 1 : Raise the rear of youre xx and place stand or support under the rear of the frame.

Step 2 : Remove left rear wheel.

Step 3 : Remove hub nut split pin and loosen rear axle hub nut but don't remove the nut just yet.

Step 4 : Remove split link and chain.

Step 5 : Remove sprocket bolts.
Tip : To loosen the sprocket bolts , I jam the socket bar against the frame. This I found the best way to loosen the overtight factory bolts.

Also I cut down a 6mm allen key to fit into the gap between the hub and hub carrier . It measures 10mm of shank.

Step 6 : Slide the sprocket outta the frame , lower end first . You may need to just slightly push the plastic a arm gaurd down. Then just simply slide the sprocket down the driveshaft.

And thats it. Simples . Even with taking the pics etc ,it only took 17mins. I hope this helps.:D

When fitting a new sprocket always put some sort of threadlock compound on the sprocket bolts and don't overtighten them.

wow! that still looks like a pain in the ass to do but i guess it isnt! thanks for posting this, i need to sevice my drivetrain front sprocket, rear sprocket, and new chain this winter!:xx:

Lee, What is the size of the socket for the hub's nut, should be a 30mm, right?
What rear sprocket are you using, ali or steel or OEM which seems to me to be the best one since mine lasted 3 seasons.

Mine was a 27mm or 1 1/16" socket and lock the rear end with the rear brake or a 2"x2" on the lug nuts. Don't just put it in gear, I think this maybe why the shift drum failed on me.

As for sprockets , still using stock but they are only lasting 8 hours on a stock motor with me. Gunna try a Ali one from PBI .
I can get a 37t Ti rear at $147 from Sidewinder ( something I found out trying to find one for Wayne M. ) or get Talon to make me a steel one far around $200 . I am guessing a Talons price as the front 17t and 18t cost me $85 a piece to be built. The cases have to be modified (strengthend) , just incase the chain wanted to run loose with the 18t. Trust me it is close ! But I need to make the 18t front work with the 3 speeder.

Wow! Glad that I check with you cause the manual shows a 30mm "adapter" which I presume that means "socket" lol! Since I don't race, the stock sprocket should be good enough for me since it lasted over 3 season and honestly after inspecting the old one, it still looks pretty good "U" shape but since I'm replacing the front sprocket and chain, it's best to also replace the rear one.

18T front, that's pretty tall, don't that bog down the bike or do you have someone pushing you at the start, lol!

Thanks Lee
