Broken Powervalve Stem
This is the second failure I've had like this with a stock PV. I was talking with Lowell about getting a replacement machined for the 1300 piston. He mentioned that one generation had a brass sleeve and another generation had a steel sleeve, but couldn't remember which is older. Can anyone clarify this? This one has a steel sleeve.

Screw the OEM PV's. I'm going with R&D billet PV's. They're "guaranteed never to break in any condition".

More than likely your adjustment is too tight. Very common for this.
