Gotta question for you. First quad I have ever owned. In CT it is starting to get cooler. Around 30-40 degrees. The machine is stored in my shed which is usually in the shade so in the shed it is actually a little cooler. With that, the bike has a hard time starting and once started, it has trouble staying running until I pretty much rev it up for 10 minutes until it warms up. When I initially start the bike (yes I have the gas on) I have choke all the way on and it barely stays running, then it will stall. Then I start it again and it runs for about 30 sec then stalls. Then I back off the choke and it starts breifly then stalls. This goes on and on for about 15 minutes and I am getting frustrated cause it only has 120 miles on it. So what I finally end up doing is turning the choke off and pressing the throttle about half way to 3/4 of the way down and reving the machine up until it warms up. When the bike is warm, it has no problems kicking over.

The point is, isn't that what the choke is for so I don't have to stand there and hold on to the throttle?

Does anyone have any suggestions on what I can do or better yet what I am doing wrong?? The book is worthless. I am going to have to get a tech manual

 

[img]i/expressions/face-icon-small-sad.gif[/img] I know the feeling of cold start. The choke lever should, once it starts,be slowly moved back towards off ,part way will hold idle up until warm up is complete. They are very cold blooded engines.[img]i/expressions/face-icon-small-happy.gif[/img]

 

Where the throttle cable connects to the throttle lever there is a rubber boot. If you slide this back a bit from the throttle you will see an adjustment dealy (I think that's the technical term). You can use this to set the idle higher while the machine warms up, then you can go inside and drink a hot cocoa. When you come out, back it off again and you're good to ride.

My brother's '02 375 is also a hard starter. Takes multiple tries and a lot of coaxing, though we suspect some of this is due to the dirty air filter (I must remember to get that cleaned!).

Interestingly enough, my '02 400 starts up fine every time, though it doesn't like to be ridden until it's had a couple minutes of warmup.

 

Yeah..I have the same problem with my 2002. I have about 150 miles on it. It doesn't crank very long before it starts (unlike my Honda) but it takes awile to warm up. I'm a little impatient by nature so I run it about 1/2 throttle for a minute and then I can usually back off the choke all of the way. If I just use the choke the bike will idle fast by itself but it takes alot longer to warm up.

I'm coming up to my first service with the dealer and I'll mention it then to see if there is anything else I should be doing.
