Hello everyone, im going to be installing a 13 tooth countershaft sprocket on my 2012 klx 250s just wondering what the torque specifications were on countershaft sprocket nut?

 

Manual at the link, '09 manual is valid for '12:

You'll find it in the service manual, no one is going to remember that. I just wanted to warn you they're a bitch to get off, so you'll probably need to use an air gun. I've heard after you crack the nut for the first time it gets easier. [Insert crack here]

 

That's the truth! I used a 3' breaker bar to reduce the risk of damaging the shock forces an impact wrench may induce. Let me tell you that even with all the leverage I had it was still no easy task.

I also found that the C/S nut 'retightens' over time making it just as difficult to remove subsequent times too. The last time I reinstalled it I used some anti-seize compound so I am hoping that will reduce the effort to get it back off next time.

 

Thank you for the quick reply i will ask the dealer when i pick up the sprocket for the specs. Last time i downloaded manuals on the internet i picked up a nasty virus. The nut came off easy i stood on right side of motorcycle right foot on brake leaned over the bike and it came off pretty easily. Thanks
