He'll never notice any power lost. The above post are taking about ring wear and piston seizures. That's way I said on the intake side with incoming air and fuel blow by would not cause any piston problems. On the exhuast side blow by can be a problem with sticking rings, Hot combustion gases breaking down lube on the piston and cylinder wall and then piston siezure.

Here's a quote from his E-Bay Auction:

Wiseco called me when they developed the KX500 piston because they were burning out starter motors on the dyno. They sent me the KX500 jug and I visited them to see the development work continue, their dyno was loving it and your feet will too!

I'm going to ride a District 36 Enduro tomorrow here in Northern California and I'll give you a ride report later.   :D

hughes:
Can't wait for the report. GOOD LUCK.

Kawadougie:
Unfortunately I came down with a flu bug the night before the enduro so I didn't go.  :cry:  But I have put about 200 miles on the release equipped cylinder and I can tell you that it works awesome!  :D  Even my friends who were reluctant to ride my bike are taking turns now.  The photo below was taken yesterday after I ran a light hone through the cylinder and installed a new Wiseco piston.  No flaking of the liner at all.  Also, the piston was unmarked on the back of the skirt where it travels over the release port.
