What octane gas are these for? I run 93 octane reguarly. I might be a little rich... Would it be ok to lean it up some?

I think it would be a matter of if you need to change plug #'s. Maybe I'm wrong though. Either way it looks like your running rich. Was that after running it around for a bit? Was it a new plug to start with after your build? Higher octane fuel burns slower so if anything it would be running a little cooler cyl temps if I'm not mistaken. Get ahold of Eric if thats who's stuff your using. He will set you straight I'm sure.

cooler temps and less hp with stock compression

High octane isn't required until you raise compression. The plug does look a bit rich though, Are you running the recommended programmer settings?

 

[jfdanie2]

Those dobeck programmers always run a little rich, you could get a hotter plug that may help

There is a sticker on my gas tank saying to run premium from factory.

What year do you have, I've had a couple 08's and never seen the sticker. I'm not sure why they would suggest it though, 10:1 with an aluminum head wouldn't raise flags to me

 

[jfdanie2]

I have the same sticker as well

 

[traitor08]

08, I bought new so I know its factory. It is above the gas cap if you are sitting on it. Between the cap and bars.

I also have that same sticker on my 08 that I bought new

 

[traitor08]

But you are running way rich. I don't know what part is doing it though. Over loading at idle, or wot. But somewhere your rich

:xx:

I have the same sticker as well

they all come with 93 sticker after about 8 months later from being new , the pressure washer an me spilling gas on it f3cked it up and it come loose on my 700XX

My sticker is still there after 2 years of use. I my be wrong but I use 93 octane in all my quads and lawn mower, always have.

I also have the sticker, bought the unit new. it says Recomended fuel is premium

Personally i run 50/50 aviation fuel and 93 pump gas with a 8oz marvels mystery oil per gal when im going to race or run WOT because of better throttle reponse... just trail riding is straight e-free 93 pump gas.
