    I am looking for a little guidance regarding the possibility of using a BB exhaust from a 733 on a 635.
    Needless to say it will need to be shortened, is it possible to simply cut the pipes?
    Some how I imagine it's more complicated, if at all possible
    Thanks

    yes you can cut the pipe and just purchase some exhaust clamps that seal to the pipe size. But I would be curious to see if the bb exhaust bends will match to the 635 exhaust ok enough for you to cut match up and clamp.

    Thanks v much for your thoughts. I think it's too much risk and cost.
    I've found a proper exhaust built for the 635, from Ireland Engineering.

    Probably a good-bit less hassle over time - good choice, imo. ;)
