OK. got stupid with the enter buton but i still need help. Recentlly moved to Big Bear Ca. altitude is around 7k. Went to start up the Raptor the other day to warm it up for an oil change, it started with the choke on and ran for a few minutes then stalled and I cant get it re started. I've got spark and the plug lookls to be fine (has less than 20 hous since new) got fuel and it appears to be flowing when I removed the lone from the ****. Thanks for any help.

 

My 04 did the same thing. I had to put a screw driver against the carb bowl and tap it with a hammer very lightly on each bowl. It seems that the floats get stuck sometimes and when it did start to run it ran like **** then I had to tap it a few more times and it worked.

 

Thanks for the 411, I'll give it a try.

 

Open the drain screws on the bottom of the carbs to see if gas is gettting into the carbs. Like Raptorowner said the floats might be stuck keeping the needle valve assembly closed. If it's been sitting a while (months) If this tapping thing works I'd clean the carbs. If no fuel comes out the drain tubes then you'll have to open things up to see why the needle valve assemblys aren't working anyway.

 

Spend a weekend day taking the quad apart, pull the carbs out, pull off the bowls, clean them up realy good, change the plugs, coolant, etc. I have done this on 4 of my friends bikes and they always run better afterwards.

 

I would just tap on the bowls like RaptorOwner said, and my suggestion is even though it is new, check/adjust the intake valves, Doesn't make much sense to me why it would just quit starting but with mine it was instant, not gradual, I had to adjust my intake valves because it just wouln't start without a push.

 

Yes, I had the same thing happen on my 02 model. Just up and quit and went thru h3ll trying to locate the problem and it was the valves all along. But since this is a new bike I would think it was the same thing as my 04 did to me. It ran but then died and wouldnt start. So that says to me its not getting fuel. Like you said it wasnt gradual, it just wouldnt start one day and after tearing it down for a few days I finally checked the valves and the intakes were way too tight!!

 

My "01 did it and found that my float valve had crud built up on it...I had to take out the float and clean the valve it has been fine..

 

Have you checked too see if the engine is sucking air around the intake boots? The engine may have burbed and dislodged the carbs.
