    Quick question, replacing the front sprocket, is the bolt right or left hand threads? Also, do you guys use any thread locker, and do you torque the bolt when tightening it?

    1) Right-hand
    2) I don't, but others I believe have used Loctite blue 242/243 (Semi-perm). Not sure what the service manual recommends.
    3) I do. But in a pinch you don't have/own a torque wrench, you could tighten (don't over tighten) - then ride your nearest AutoZone (or parts store) and rent/borrow one to torque (or do it before the job starts). I recently changed mine out on the road (far from home) and rented one - which cost "net" $0. Just had to put a deposit worth the tool while I borrowed for two hours.

    What do you torque it to?

    I don't have my specs in front of me at the moment - but I believe it's 40 n/m. Other may need to chime in here....

    I do it up tight by hand and ise one drop of Loctite. Have done it the same without Loctite for years without any ill effect though.

    Use the torque wrench....
    You'll get a very sick feeling when you feel it break off while you over tighten it... Ask me how I know....

    So I changed my front sprocket today

    The JT I had was a poor fit compared to a BMW, so I have decided not to use JT

    I now have a genuine BMW 15t front sprocket

    Does anyone know if there are any 14t genuine BMW sprockets that fit?

    I'm in need of a new handle bar. Do any of you have any thoughts on oem vs. aftermarket? Is there any size / bend that would be preferred? If I go aftermarket?

    What about it didn't fit well? I'm getting ready to install a JT 14t myself

    It was looser on the splines compared to a BMW sprocket

    BMW does not make a 14T front sprocket for the X bikes.

    The JT spline fitment seems to come and go, some fit, some don't. Good that you checked it first. Too loose and you'll damage the splinea.

    Go to a 49T rear. Very similar gearing change and easier to do.

    Aftermarket is less expensive. You can buy used handlebars for almost nothing to try different bends to find one that suits you.

    Remember that you have to pull the locating pins out of the BMW controls to use them on aftermarket bars.

    But do they make any others that fit, I.e sprockets from a g650, f650 etc can fit

    Any other 650 rotax run a 14t sprocket?

    The X bikes and the new Sertao are the same engine. They have unique output shafts, so they do not have cross compatability with other rotax engines.
