I'm looking for a set of 650sx cheater head domes in the 30cc to 32cc range. I have 28cc's and my compression is at 220lbs! A tad bit higher than I want to run. I don't really want to send these 28's in to be cut!
Thanks

Is this the head that west coast made in late 80’s early 90’s? They machined out a stock head to accept domes. If so I believe you just need is the WPP 650 domes and the special head gasket. I had a few of those 750 heads in early 90’s and they used same domes as the aftermarket WPP head. It looked 100% stock. Lol

Yep it's the same head. I like it but I wasn't sure what domes it could take? I'll look into the WC dome. I've never heard of a WPP?

Those heads weren't for cheating, they were for the limited class where a stock head casting was required. The only advantage would be if a Rotax style combustion chamber was desired. Otherwise you would just use different heads.

Yes, they were called a cheater because you couldn't see the difference between the two not because of of the limited class. It was only a saying, ya know like a sleeper??
