    Lightbulb 87-89 swingarm

    Will a 89 swingarm fit on a 87 TRX 250R. I think that the motor mount may have to be modified. Thanks for your help.

    swingarm bolt does not go through the engine but there is a set of engine mounts that it does go through. 88-89 could go on w/some modifying but brobably easier to just get an 86-87 swinger

    You'll have to take the center rear motor mount from the 87 and cut the ears off were they mount to the motor and weld them to the top of the bottom frame rail so that you don't loose your rear mounts. than you can install your 89 swing arm. It's not that hard if ya have a some patience, and someone who can weld.
    Experience is something you don't get until just after you need it.
