    Engine Discussion
    First post, been lurking for a few weeks. To make a long story as short as possible - I bought this bike for a couple hundred bucks. Decided I could make it my project.

    Other Bikes
    Howdy fellow wrenches (wrenchers? Wrenchees?), I'm having a little issue as I'm putting my '93 XR250 back together.

  7. Engine rebuild or replace?

    Mechanical Issues
    Completely restored my 1972 CL350K-4 and got about 1000 miles out of it then it blew a hole in a piston. I have a "modern mechanic" who is willing to try to repair and trouble shoot but at what cost. I think I'd be better of finding a completely rebuilt engine and just replace it. Any...

    What do you guys think about this plug? They both look exactly the same, but I'm not completely sure if this means I'm running lean or rich. Thanks for any help.
