Recently I bought a 07 350 Utility, that had came from a estate. Terrible gas mileage, only 16/17 to the gallon. I figure it should be at least in the 25/35 range.
Probably varnished up, just sitting after the original owner passed away.
I changed the plug, cleaned and reoiled air cleaner, didn't make any difference. Had to adjust the throttle stop screw so that it would even start.
The goober at the dealership, wasn't any help. He told me to run hi-test gas.
To make a long story short, whats the best carburetor cleaner that might help me with my problem?

But I think 16/17 is the norm of what you have. Remember it's geared low and will not get the same mileage as it's street bike conterpart.
dano, thanks. I just looked at my Yamaha repair manual but it didn't list the name. They are fairly easy to clean. Even i can do it on a good day. If it has laquered up, it is a chore to get the little holes as clean as they shud be. Welder's torch tip cleaners come in handy sometimes. Tom
Be careful with the torch tip cleaners.
You don't want to change the shape or size of the very small holes (jets)
Some of the cleaning products work well after you take the carb apart and apply it to the hard to get at areas.
I've used spray on paint remover with good results, be sure to wash it off so as not to eat up some of the lighter medals used in the carbs
You won't have to take the thing, just take apart enough to blow it out. I'll bet there is something stuck in one of the jets.
You may ask another 350 Grizzly/Bruin/Warrior/Raptor what kind of mileage he's getting. Like I said, I think 16/17 is the norm.
I have only 2 stroke Yamaha's and I get maybe 5-8 mpg depending on how hard I ride. I've gotten as bad as 5 gallons in 20 minutes.
I do have a 400 4 stroke Honda. I get around 20-25 mpg with it, but's it's a sport model with a standard gear box and chain. I'll bet yours is a automatic with belts and a shaft. It may even have a rear diff.
I do have a 400 Kawaski with an automatic with belts and shaft. I don't ride it enough to know my exact full milage. It's alot less than my 400 honda EX, but alot better then my Banshees.
as I only fill it up once a year.

Thats exactly what it is! Grizzly, automatic, 4 WD, lockers, irs ect. I guess the original owner, wanted all the bells and whistles. To bad he passed away, less then 6 months after he got it.
Thanks for the heads up! I guess the gas mileage, isn't that bad. I'm just going to dump a can of Seafoam or some other carb cleaner, into the gas tank, to see if it will make any difference.
I see guys all the time with 700 plus 4x4 thinking they are going to go anywhere the smaller bikes can. Then quickly learn they are too big and heavy for the tight technical stuff.
You can't beat big cc's for towing though.
This may sound crazy, but the best carb cleaner I've used isn't carb cleaner. It was STP dexcon trans fluid. Mix to a 1 to 60 ratio.
You find out that very few critters will * at the sight of a 4 wheeler, ATV, or whatever they call them where your at. At least until you get off it, then they seem to disappear pretty quick.....
