    Hi the jets in the Mikuni carb of my 250 wr 1979 are worn and I can’t read the numbers can someone tell me the standard jet size.

    I’ve got a excellent condition Keihen carb of a Honda Redrocket would it be ok to fit and what jetting would you recommend starting at.

    Also can someone give me the squish setting and timing settings

    All help appreciated
    Thanks

    According to the Husky manual - the main jet is a #430 and the pilot is #45. The needle jet is a Q8.
    This was just the base line setting. It will depend on the altitude and type of riding you do.
