I have an 03 Warrior and an 05 YZF450 both are stock i was wondering if it is safe to run 110 octane gas in them with out rejetting. Thanks in advance

 

There is no need to run that type of fuel you will actually degrade you performance.

 

Welcome to the forums Fattie. He's right. 110 octane will slow you down...unless you have a high compression piston. You should try an 87 octane compare to like a 91 octane. It may run better. Lower octane fuels have a higher flash point.Works better with low compression.

 

The only thing you would get out of running 110 octane in stock bikes is a big hole in your wallet. Unless you get into high compression, such as 170-210ish, there is no need to run that high of octane.

 

thanks guys, thats what i was figuring. i justb wanted other opinions.

 

i have a je 10.75 to 1 piston and i run about 100 octane. is this ok?

 

I have a Ross 10.75 to 1 piston and I run 87 octane but I have a bigger bore so I'm not sure...Try a 91 octane and see. Plus it's cheaper.

 

RIDEFREAK1 your a little high on octane with a true 10.75. Like ItalianStallion does, it should run on 87. You really should have no problem at any time, under any condition with 92.
It's always good to go a little higher than needed when it comes to these things, but never lower.
