Wow, I wonder if it was a bad bore job? I wouldn't think it would go bad that fast.
That's exactly what the guy said. Nothing to do with it going bad, it just never started out good. So if that KTM of yours ever has to go under, you may want to find a new guy.
But even with that cylinder it still ran! Now that everything is back together I got to take it for a spin yesterday and the motor certainly is a little more snappier.
Now (always something) that I have put a new front tire on, the front end has got a annoying wobble/pulsation when riding down the road. I balanced it once, but no help. So I may rotate the tire a bit and start over....
