O-Ring on a

[Sticker Otis]

Has anyone here tried running a o-ring & groove on a blaster ? Just pulled our 240 apart and it looks like there might have been a small leak in the brass gasket. I lapped the head & cylinder so I'm sure they where flat before torking & running. Anyway, it's apart and I could easily turn a grove like the YZ has. Guess unless someone says "oh no, don't ever do that!" I'll have to give it a try.

I've seen a stock banshee cut for orings.. Tyson Racing does the work!

an o-ring head on an air-cooled motor?? wouldn't the heat generated from a blaster motor just cook the o-ring? I don't think I'd ever try it on an air-cooled motor.

Good point, that's the kinda feedback I was looking for! How much heat can neoprene handle? It's between the cylinder & the water jacket on the YZ so doesn't the heat have to pass through it before it's removed? Hmmmmm. Now I'm worried

I wonder if you could find a copper o-ring the right size?

The metal o-ring wouldnt have the same properties as the rubber/neoprean.
I would just stick to the copper head gaskets, However if you feel ambitious call Cometic Gaskets & I'm sure they can make somthing for you thats better than stock....Just ask them.

Why can't you use piano wire o-rings like cars use in supercharged applications?

[lt250racer]

You would have to find a metal that expands the correct amount at the right temp.
