i was tuning my atv and it seems everytime i press the gas, it feels like somthins holdin it back. but its not really back firing or smoking. is this a lean or rich condition?

 

check and see what ur spark plug looks like, if its black, it's rich, if it's white, it's lean, prolly gonna be on the lean side

 

my problem is i cant reach the damn screw so i have to keep pullin off the carb and turning the screw. the settings sound good i have the fuel screw set at 1 3/4 turns out. but when i drive it at full throttle it seems to bog!!!!!! any idea?

 

it's probably running a little rich, pull the airbox lid off and see if that helps, if it does then it is too rich and you'll prolly have to rejet it, your fuel screw controls your idle circuit more than ur main circuit. if the airbox lid makes it worse, then cover part of the snorkel on ur airbox lid with tape and if it runs better that way, then ur lean

 

im just wonderin, i got the 06 hawkeye 4X4 and people have said it sometimes comes rich from the factory. i just checked my spark plug and it is BLACK, like a piece of burnt wood. is it probably rich?

 

Most all bikes are a little rich from the factory. Being rich is a lot better on the engine than being lean. A lot of people are chaning the main jets out to get a little extra power from the factory.

 

I heard that all Polaris quads run rich from the factory. I guess it's true, but at least that won't burn a hole through the piston.

 

does it really make a difference with the airbox installed? because im just tuning it with the air filter on. what controls the main circuit then?

 

Here is some good reading for you.

 

okay if main jet jet controls high range. is it adjustable? because at idle and quarter throttle the atv runs good. only at full throttle it seems to bog and no power.
