XR80 head on a XR100?

[JLC]

What is the low-buck method to make this work? Just a glance today says that the 80 head has a larger combustion chamber. Other than that, will it work? Can I get a 100 dome piston?

thanks

I have one on one of my motors with no mods.

How do they run?

I think the Combustion chamber on the XR80 is a little smaller than on the 100.

The head I put on was extensivly ported and machined for a little more compression so it's hard to say what a stock 80 head would be like.

Update--- ? :thumbsup:I put the 80 head on the 100 and all seems fine. My foot tells me that the compresion is about the same or maybe a little less?? Thanks for your imputs and you will probably be seeing alot of me in this forum as I now have 3 z-50s and 2 xr80s.
