Can you get race fuel or special OXY fuel (MR12) in Kuwait? You will get a lot more performance with a high compression piston. IF you really want to make it a beast have Geoff covert it to a carburetor, the fuel injection throttle body really holds these YFZR's back.

we can get race fuel, but we use the yfzr for long periods of time, so when its out of gas its hard to refuel, because we ride sometimes on the sreet and the desert and we can go to gas stations to refuel

as for switching carburetor, the main reason we got the R was it's fuel injected

i'll see what Geoff would recommend and report back
