Hey guys,
Been having this problem for awhile. Grizz won't start when it is cold. Brought it in, Dealer thought it was my thick oil (that they put in) and the wrong plug was in it.. My fault on a bad cross reference... Anyways, I have tried everything, Full choke, no choke, half choke, full choke half throttle everything! It will not fire when cold... Heres the twist. After I have been cranking on it for a bit, If I hold it WOT, and pull it.. It will fire a little... Seems like its flooding. However, if I do the EXACT same thing with the electric start, it is like its not even sparking. It Just cranks over. Eventually I can get it to start by pulling it only.. It runs really rough, and won't idle. I end up holding the gas in for a bit till it warms up. Soon as its warm, it will idle, and will start with a half click of the electric start. Any ideas? I am taking it in AGAIN and am starting to get frustrated.... Over 1000 miles on it, Its a great quad, but this sucks... I am at a loss.

Hey brother try this when it is real cold turn the key on and wait about one minute. The 660 has a heating element in the carb for cold starting. There is a thermal link on it and I don,t know at what temperature it turns on but I think it is some where around 10 degrees. I had the same problem as you one morning. It was colder than blue hell and I could not get the old girl to fire. After cranking the bitch for about 45 seconds I got jerked and just let it sit there with the key on after about another minute with the key on I walked over and hit the starter button and it lit right off. While riding I was thinking about something the salesman had said about a heated carb. So when I got home I checked the carb out and seen where the heating element was wired in. Big bore singles are notorius for cold starting problems and rough ideling until they warm up a little. hope this helps.

I've never not been able to start my Grizz, but I can tell you that my two Yamaha's are on the cold blooded side. The good news is that they are coming out with a block heater for the 02 Grizz. It's already out for the 02 Kod, and so far the 02 Grizz's block heating is still "to be announced"...but it's coming, and I will get one when it's out.

Hambone- Thanks! I never knew this, I will have to give it a try.. How much are you choking it?

Silverbear, About the block heater.. What good is it going to do when I stop out on the trail? Its just frustrating paying 7 grand for a piece of equipment that is intended for offroad use. And it won't start!


I have had trouble getting it started when its below 40. I think something else might be arye....

I have a 2000 Warrior that is hard to start also when cold, Dealer said to run the carb empty when I'm done riding it..Seems to help some, Also do this omn my friends 2001 Grizzly, seems to start up faster, but it won't idel till it's really warmed up..

Anyone have a way of keeping mud out of the air cooler on the Grizzy? Seems like every time we go out we have to stop an let it cool down due to the mudd building up on it..

On the trail? Absolutely nothing unless you find a current bush to plug it into. [img]i/expressions/face-icon-small-wink.gif[/img]

I didn't realize you were having the cold starting problem out on the trail. The coldest on the trail I've rode in I think was only around zero, and really never had a problem starting it back up. 'Course when it's that cold I'm not roasting hotdogs over a camp fire either, so it doesn't really sit a long time.

I just know they're cold blooded starting in cold weather after not being ran for a few days, and in that case the block heater would be an exceptional addition to the quad, and that is the scenario I thought you inferred.

Silverbear,
Don't get me wrong, It would probably work great for its intended use. I might even get one... Problem is, When I am out on the trail, or out on the lake ice fishing for the day, It won't do me any good. It also seems like an unneeded hassle. Just kind of frustrating like I said. Sorry to come off like an ***, Thanks for the advice.

Don't sweat it. [img]i/expressions/face-icon-small-wink.gif[/img]

I wondered if you were an ice fisher. You've probally already done this, but have you checked your plug? Mine started getting harder to start over time, and it was the plug giving me that problem.

Hambone's suggestion is great. I can't find anything about this thermal link in my service manual, but am going to go look for it on the quad too.

If you are hving trouble getting it to start at 40 degrees you have a problem. Mine gives me trouble only when it sits all week at near zero conditions. It always runs ruff until it warms up for say maybe 5 minuets or so. check where your choke cable goes into the carb to make sure that the cable retainer has not backed out or something of that nature. I know a couple of guys who own the 660 and they have no problem starting them when cold. say 20 degrees or so.
