my worn topend
« on: July 10, 2011, 07:02:08 PM »
well, today my topend gave all it had. Compression test showed 65psi. This is my dad pushing it, I'm on the camera.

Gotta love 2 strokes. I still rode it all day and it still starts 1st kick.

Try that with a 4T! You have to be careful about letting a topend go too far as a loose piston will start to damage the cylinder's nickasil plating. ;D
