This is what my piston looked like when I took the motor apart. Part of it wedged in the oil pump and cracked it and another piece was by the clutch basket. Motor wasn't making any noise but it was starting to smoke...

Dog86, a stock piston will not be needed but thanks anyway. I've had these parts in my garage to do this 719 for over a year and I am finally getting off my lazy a** to get it done. I had no clue the piston was even messed up. I lost to a 450 the other week and it got me motivated to get working... :)

Not to be rude sounding but that is something that you need to ask willy.

Oh, no worries, I will do so, I just figure that Willy being the helpful person he is would probably chime in here sometime and either explain what it is or point us to a link on where to find it. I couldn't find one myself. If he would prefer we contact him about it, that's not an issue either.

The oil mod is free for the asking, but you must PM me..............:D
