I know this is a ATV chat room, and I know its a dirtbike question, but I dont know where else to ask it. For all of you with 125 cc dirtbikes, how often do you have to rebuild the top end? And after you've done that, how long do you break it in for? Thanx for ANY replies.

 

If I were you I would go here www.extremeatv.com and ask that question.

 

Depends on the riding you do. Once a year for a novice MX racer is usually enough.

I have seen non-racers go two years.

Competitive racers will change the rings once a month.

Once you do it once, and see how cheap and easy it is, I imagine you would do it at least once a year...

 

Hey I saw that you tried the site I recommended. Good deal, I hope they were able to help you.
Later.

 

Yea I did, and they answered my question pretty good, thanx TwinShot
