I want a bore kit for my raptor but i still want to trail ride and don't want to run race fuel through it. All the kits I see are running a 11:1 or higher compression and i was told you need to run anything higher than 10:1 on race fuel. Any suggestions.

 

It should be fine on premo but a little mix 25% might not hurt.

 

Mine is running fine on Premium unleaded.[img]i/expressions/face-icon-small-happy.gif[/img]

 

xtremeraptor what are you running for a compression ratio.

 

stay 11 to 1 or lower for saftey

 

I hate paying 4 dollars + a gallon for gas...

Not to mention 3.50 for a quart of 2 stoke oil...

 

Yeah i feel the same way reptar660r. And thanks for your input everyone.

 

I had a DRZ and that was 12.2 to 1 compression and it ran awsome on 92 pump gas. I don't think you would have the need for race fuel.

 

11-1 will run on super unleaded (92 octane) most of the time but not 100 percent of the time.

air- I think you out to check your TRUE compression and not go by what you were told. I will give you a little credit on head pipe size, the stock size is good for 99.5 percent of the people

 

So what does it take for the other 0.5% of the people to need to get the larger diameter headpipe? Cause I was thinking of ordering the MBRP race head pipe and having it ceramic coated inside and out.
