The XT550 Thread: Info, Stories and Mods Inside!

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.

great pic, open spaces.

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.
Just did this :)

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.

For sale?

Can you be more specific? Did you lathe the top of the piston? Cheers

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.

Replacement shock available for the '82 XT550? Thanks.

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.

Thanks for the offer.

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

Xt600 front end fits, and you cann still use the speedo.

Wilbers, Yss and I think a few more makes them, check ebay :)

Hi All,

It has the cool mod for the balancing of fork air pressure. I always wanted to make it and then swapped the fork for an XT600 fork

Anybody on the east coast looking for a wild child XT550? I've currently got mine up for sale.
