Ummm...Wow. Sawzall + piston = Not a swell idea.

If you could use it, which you wont, right?? It looks like a 10.5 to 1 piston and is more than likely a Wiseco. The 12 to 1 compression has a higher dome.

ok cool thanks guys

Wow. That's not a piston, that's a hand grenade. I hope you won't let this guy work on any of your trikes.

That piston has been shaved for a stroker and is the one that Helm and Son used to sell. They came out of Taiwan years ago and are very brittle. I have seen one shatter into a million bits.
