    Magnificent result. I wish my 550 looked as good as that.

    Love this turd, but thinking about passing it along. Not sure what it's worth anymore, what do you guys think? WR450 forks, it465 rear swingarm/wheel/shock and yz250 seat. Super niche I know, but got a bug lookin at the old Eddie Hau 550 enduro bikes a while back. It's an absolute trail beast and the teraflex tire is lethal in big gravel, especially if you're behind it. Just looking for something with...more parts availability.

    Another lock down in UK. Guess its time to take the XT on a few rides to get away from the house. Only thing to keep me sane.

    I haven't posted anything here for a while. Hope everyone is doing well. Here is a picture from a few weeks ago.

    Hi All,

    I am brand new to this site and just inherited a XT550 in pieces. The piston looks shot and some rust on the barrel can anyone point me in the right direction for an oversized piston - make, dimensions etc? probably need to go a couple of sizes up. If I had a comment to make on the 550 I would swap out the fuel tank with a 500 to give it that classic scrambler look.

    Xt600 piston and a rebore of the barrel.
    The piston needs to have a slight amount of material removed bu the valve pockets.

    I have a 600 jug already bored with the Wiseco piston it was bored for. 96mm std compression, pre '88 IIRC. Should have a 600 head for better flow as well.

    Yes, there was a small lip on my 95mm TKRJ brand xt600 piston, which was machined away.
    I think it was something like 0.10mm high.

    Its the "outer ring" in the attached picture.

    Yes, but depending where you are shipping may not be worth it for you.

    I have just bought a good second-hand front end for $200 from a Honda 230 (shocks, wheel, fender, disc brake) primarily for the disc brake set up which fits nicely.
    Currently looking for an XT500 fuel tank as the original is somewhat ugly.

    How it looked yesterday and started to paint the frame white for that classic 80's look. Pic showing replacement IMG_3834.jpg front end from a Honda. IMG_3824.jpg IMG_3834.jpg IMG_3834.jpg IMG_3836.jpg
