What are you King riders running for gas? Reg. unleaded or premium. My V-Strom with EFI ran better on reg . Just wondered if anyone felt any diff. Pete[img]i/expressions/face-icon-small-confused.gif[/img]

 

Although I do not own the machine you are refering to, I will say that 90% of quads made today only need 87-89 octane. Once you start raising compression, advancing timing, then octane should be raised. Just a little FYI for ya.

Edit: Alotta people say that they put 50/50 race gas and 93 octane in their stock machine and it was faster, but I find that every one of these statements has turned out to be false, and in 2 small bore 2stroke dirtbikes that I rode with this, they actually ran worse!

 

Owners manual says 87 octane.
