K guys the snow finaly melted enough i could get a good 30 minutes to an hour of running in. It sorta sputtered when i got close 2 the rev limiter and after i shifted but over all way faster. Started fine but when i tested the plug it still says its running 2 lean. The plugs not brown or black just looks almost new and the tip of the thing u gap on it was brown.

If he is then a black plug would be evident but he said it's still white.

Yeah the electrode is still white. Almost looks new still. And the very end of the tip is brown and the part where the treads start is like a white color. Could this b because im running like 110 octane fuel?

You dont have the internal mods to run that bro... I don't even run that high of an octane...93 is all you need of course your plug is going to white you didn't mention your burning racing fuel......try low octane and see.

I truely had no clue that would make so much of a difference lol. I always run it in my truck when i race and stuff so and when i wanna clean out the injectors and stuff so figured it worked the same with quads? Should i just run like reqular unleaded then?

First off,you race the truck in avatar pic?

Now here are some things to also look at.

Are you gaped right,is your plug a hot or colder plug.
What are you running air box?stock? these are all thing to consider for a correct gap,plug and jet.

Also 110 is not the only thing to blame,you may need to adjust the air fuel screw.

You can run 87 fuel just fine,but I would say run 89,base set the air/fuel screw,run your current jet and run a colder ngk plug.Play with the gap some as it will make a huge difference.

Agree^ I actually cut the tip of my plug back so it's half way over the electrode..... in cars I read an article in a mustang magazine that stated a 3% increase over stock plugs. I figured it was worth a shot.
