hey, just got a brand new grizzly 660 and have a couple questions.1st is how long should it take to warm up ?i let it run for 3-5 min with choke on and then when i put in gear and give sum throttle it just stalls. i know its -30 out but is that right? also i just had it back to the dealer to get a back seat put on and when i got home home and read the work order i noticed that they said they had to replace a spark plug because they couldnt get it started and when they did get it goin they said it was backfiring and mising. they never said anything to me about it when i picked it up so was wonderin what you guys thought about that??3rd thing is after about 30min of riding the gas gauge drops its first bar everytime, i didnt think it would go through that much gas and its not like i have it open all the time, so is that normal?they are just not greaton gas??this is my first 4 wheeler so dont know whats right and whats not any help would be great.thanks

 

well after u let it warm up for bout 5 min.
u gotta take it off of choke when u put it in gear so u wont flud it out.
and the gas gauge is not all that accurate.
mine does the same thing but the last two bars last a long time.
and it will go about another hour after the last bar is gone.
no joke.

 

I have an '05 that I got a few months ago. It had a touch less than 100 hrs on it. The outside temps were in the '50-60s and I would start it with some choke then shut the choke off in about 30 seconds. Temps at -30 are a different thing altogether would require more choke especially if you still have dino oil in it. The spark plug thing sounds a little weird for a brand new machine but it might have had old gas in it and fouled the plug. If you ride at higher altitudes like I do, a carb adjustment is required and cold weather can also require a jet change in the carb. I believe that cold temps makes your carb run much richer so poor mileage is expected. Hopefully some of this rambling helps.

 

My friend has the 660 grizzly ,its cold blooded and needs a longest warm up time I ever seen on a ATV in our northern Ontario Canada winters. Even in the summer it takes time to warm up.

The plug is hard to get at so you have to be really careful to make sure it not sitting lose and is set tight.

Forget about its useless gas gauge. The first bars go out faster than the last bar ,the ATV will do close to 100 miles witout worry, use you trip meter as a gas gauge instead.
I never seen a ATV gas guage I would trust.

 

I have a 2003 660 grizzly. the choke should be full on when when you start it. then gradualy move it to the off position. listen for the engine RPM to go up as you push the lever to the right. when it is idling high it is where it needs to be. as the idle starts to drop move the choke lever to the right some more until the idle comes up again. your plug will foul out if you do the slightest thing wrong with the choke. once it floods out once, the plug is junk and it is easy to flood it out since it is a cold blooded beast. the gas gauge is wierd. i fill mine when the last bar disapears but it never takes mor than 3 gallons of gas and the tank is supposed to be around 5 gallons (i think). you picked a great quad for a first quad.

 

These things are very very cold blooded mine is rather stubborn for about the first 5-10 minutes when cold...I dont know about the whole plug thing, have never had a problem there. As far as gas they love the stuff...I have drained a tank in a half hour before running top end down the highway. They will run 6+ hours under normal driving conditions, and you can get about 23-25 miles on reserve if you run her easy. [img]i/expressions/face-icon-small-wink.gif[/img]

 

Best thing is a 45 pilot jet, one hotter spark plug and either 5w30 or 5w40 oil. Also if you use it to plow and a winch to raise and lower the blade, install a battery tender. It was night and day difference on mine, cause this things have a DC meaning battery CDI iginition.
