There are all sots of things you can do to the motor to make it scary fast. Myself, I installed a Muzzys Pro, polished the slides, installed a Twin Air Power filter, replaced the velocity stacks with 2002 Prairie velocity stacks and jetted .190. It is scary at the increase that's happened with just those mods. I have done several other mods to the bike itself and am continuing. Stay tuned for the full ATVT V-Force project with engine upgrades.

And, welcome to the site

Before you go doing all of that, check your spark plugs. It sounds like you got one fouled to me. Next, get a few sets and do some plug chops to determine whether it is running rich or lean. Generally flames out the exhaust indicate that you are running too rich.

I just put new plugs in. i have tryed 3 turns 2 1/2 and 2 on the carb and just makes it pop more

What size jets are you running?

Sounds really rich to me.

Are the numbers "FMF Jet kit Frunt [124] Rear [128]" indicating the size jets he's running by chance

My question is do both plugs look the same or is one richer than the other?

After you get that thing tuned in, you might consider some new treads. On the other hand, I'll bet spinning that quad is a blast!

That would be my first que. (LOL guess I missed that part, or forgot)

By an FMF kit, I am guessing that this kit is most likely made by Dynojet. I will need to get a cross reference to see where you are at.

What all did the FMF kit come with? Springs, needles, or just jets?

Yes they are made by Dynojet. the kit came with jets and needles. im in Florida below 3000. when i called the jets they told me that would be best for me is 124 frunt and 128 rear with stock air box. i set the carbs back to 2 1/2 turns and put a 1'' hole in my air box that got ride of the flams and it dont pop much. but still pops sometimes and dont like to idle cold when can i open up the air box with the 12 hole mod or the set up your running GRIZZLYWIZARD? Thanks for all your help.
