    Nasty Oil and Scored Up Pistons

    I was taking off the 1150 head and putting on a better ported 1100 head and noticed some nasty oil. I pulled the cylinders and saw that the pistons were scored so decided to take it on down and get the cases bored for a little bit bigger piston kit. When I pulled the clutch hub I found the problem.

    Just wanted to share this with you guys.....

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      Bad news for sure. Is the scoring bad enough that you've lost the barrels and pistons?

        Yep. Pretty bad. I have a bigger setup I'm puttin' in it so not a big deal.
