RB head and gas..
Hello!
I bought there a few times a RB Head (not for competition gas) at a member of the forum (transaction very pleasant ) I have not still installed but I have a question:
Here in France we have different fuel:
-SP95 (95 RON, MON 85); : Unleaded petrol (lead is replaced by potassium), 95 octane (it seems me it is 5% ethanol)
-SP98 (98 RON, MON 87) unleaded fuel ( lead is replaced by potassium), octane 98
-SP95-E10 (95 RON, MON 85). : Unleaded 95 octane, 10% bioethanol
Currently, my bike ride to SP95 or SP 98, and I wonder if the fuel is compatible with this new head , and which is better?
Thank you :D

SP 98, everytime, no matter what head you are running.

Re: RB head and gas..
Highest octane and no ethanol is my guess. Supposedly Ethanol in fuel can be linked to reduced life in seals (specifically crank), although most seals are viton and not harmed by ethanol. Kind of the same argument as synthetic vs non-synthetic oil...

In the USA, we have RON+MON/2, so SP98 is 92.5 in the USA.
Thank you for participating on kdxrider.net.

I run the highest octane I can get (91 around here) because my bike just flat out runs better on it.

Re: RB head and gas..
yes, any change to engine or running conditions you should rejet
if you change what gas you use, rejet
if you change what oil you use, rejet
if you change your gear ratio, don't rejet, that has nothing to do with the engine
but if you change compression and squish band, rejet
