    Help with Chumba F4
    I've got a new to me, Chumba F4 that has a little bit of lateral play in the rear swingarm. Two questions:

    1) Is the play usually caused by worn main bearings or worn dogbone bushings or both?

    2) The bolts holding the main bearings won't budge: Are they reverse threaded? Or do I just need some major torque to get them loose?

    Thanks in advance for your help.

    hey rip

    All the chumba guys are at vegas for interbike. Try emailing them but I'm sure it will take a while for them to get back to you. Call them next week and ask for Dave and he definitely will help you out.
