Who is this for? I'd like to find out the flow numbers on a ported XX and XR head before I commit to porting my XR.

flow numbers wont tell the whole story on what your lookin for

They can be helpful in making an educated guess. This isn't like comparing one porter's job to another on the same head. With one having a single and the other having dual exhaust ports having numbers to examine can go a long way. Not trying to sound the smart ass, I'm just really curious as to what each is doing considering the money involved in going with an XR setup.

 

[VelociRaptor]

I feel that a dual exhaust port is more effecient than a single exhaust port mainly for the velocity per cfm per cc of port factor.

Bo what do you charge and what is involved in converting a XR650R head to fit a 700XX bottom end, not including porting just the conversion? Do you need to run a special piston? Thanks
