    Howdy everyone, Just picked this up the other day, I don't know too much about early KTM 2 strokes but based on what info i can find so far on a few websites it appears to be a 1981 KTM 250 GS.

    Most of the bits are there, the engie is seized though and it has this large chunk taken out of the fins:eek1

    Can only imagine what happened there. This is going to be a long term build but wondering where the best place is to get advice on the rebuild? and of course parts! I'm going to try and source a replacement barrel rather then repair this one if i can.

    Thoughts, suggestions, advice all welcome!

    Cheers

    Yup. Looks like a 81 GS. Go to:

    http://pentonusa.org/ and http://www.ktm495.mxbikes.com/

    Let the process begin. You can verify year by frame/motor numbers on the POG site. Great bikes, I have one. How do you like your S10? I have one of those too, kind of a pig though off road.

    Repairing the cylinder is easily done, you dont really need a replacement.

    G'day Pete, Thanks for the links thats got me started, definetly an 81 model it seems. Yup i have me an S10 for another few days then its gettingswapped out for a Triumph Tiger 800XC. The S10's a great bike, it handles most roads and tracks pretty well and handles great on the tar. A bit on the heavy side but it hides it well. Only swapping it out as it's time for a change, and something with a little less weight and gizmo's will be nice too. I'm always worried something will go wrong and leave me stranded.

    Twin-Shocker, glad to hea i don't have to source another barrel, can any good alloy welder fix these things?

    Cheers

    I had a 81 495 once that looked just like that 250. 495 was neat but I got more trophies on my 420.
