    New Bars
    New levers
    New grips
    Refresh the bark busters
    Re mount bark busters
    Front suspension
    Rear suspension
    rebuild rims
    Supermoto wheels
    Bit brake kit for supermoto setup
    New plastics
    New headlight
    New seat cover
    New tank
    New header

    Wheel bearings, steering head bearings!! Very important on the street, more often than not you don't notice these on the trail.

    If the big brake kit doesn't include new master cylinders or calipers, at least rebuild those too!

    Took it up to walker to test out the dirt setup..

    Needed a little further adjustment to the leavers and clutch pull.

    The it ripped.. Jetting still seems good!

    Got into a HEAD ON about 15 minutes into the ride.. with a kid on a yz250. bar to bar, headlight to number plate.. fender to fender.

    Knocked helmets pretty good too.. both stayed up.. were ok, and kept riding.

    This was right after I was looking to see if any of my new shit broke!!! lol.

    Yep, steering head bearings are on the list.

    Wheel bearings will be redone when I re-lace the dirt wheels and the supermoto wheels have their own set.

    Definitely doing a bigger master and caliper setup.. Still waiting for my caliper relocation bracket from QTMI.

    Linkage and swingarm bearings. If you don't have tools, bring them by and we can do it all on the press in about 30 min.

    Might have to buy new bolts if they're really bad.
     
  10. Next upgrade=ship it to Tucson, AZ for desert testing.
