I own a 1991 rmx 250
Mods:
1994 cylinder and head
FMF pipe & silencer
mo better porting
overbore to 265
and I recently bought a nos head off e-bay and had it milled for race gas and bolted it on. I have jetted down for the race gas but now I have heard that people are milling their heads, and then running two base gaskets to change the port timing, but with the milled head it keeps them close to the original compression.
q: Has any one tried this, did you like it or not?
With the lowered compression would I mix my race gas with pump?
And any idea on what I would need to change my jetting to.
Thanks
