Anyone ever use a SXR head on a set of SX750 cyl?

I have a 2mm over (bored and ported) set of small pin cyl I want to use which makes the bore 82mm (same as the SXR) That's why I thought a SXR head would work as far as diameter of the bore..... I just don't know if it will fit....

I have a Wesct Coast head with 26cc domes to use for the stock cyls, but is 2mm over too much for that head?:dunno:

just check your sqish. r@d sells them it says 750 or 800 one part number. should be no difference

Same head, the squish is cut to 81mm standard I think, you will need to recut

Confused on your response.....are you saying I should use the SXR head?

The head gaskets for the 650/750 are the same, but not the SXR.....

Use it with an sxr gasket, just machine the squish out to 82mm

Can I just use the SXR head and gasket on the 750 cyls?
