2003 Arctic Cat 250 4X4 runs good then bad then good again

[dbconn55]

Hi guys I have a 2003 Arctic 250 4X4 it starts idles and runs great for about 10 min. then it spits and sputters and dies but it starts right up like nothing happened idles good till you give gas and it does it again let off the gas and it's idling great again this goes on for about 15 to 20 min. and then it takes off runs good all day like nothing was wrong.

I cleaned the carburetor it looked like a new one inside found a little gunk in one orifice, new air filter no crimped lines air line to tank good I did put a meter on the battery idling it said 16.5 V that's high I think would a voltage regulator cause this?

Suzuki shop wanted to sale me a stator for $556.00 but said it could be something else also thought I'd see what you guys say about it

Thanks

Irregular voltage can sometimes cause havoc on the cdi so it could be.  As long as your sure the carburetor is properly cleaned and the fuel line going from the tank to the carb is good then I would focus on that voltage right now. 

That’s pretty high for a voltage reading. Should be no more then 14.5 so I would guess it’s the regulator but I would do a little testing before you buy or order anything.  That stator can be purchased a lot cheaper elsewhere also.  

Download the manual and get a tester, start doing some of the standard tests on the regulator and stator and go from there.   If you need any help with that testing let us know.

16.5 volts is too high, that would be the regulator going bad. A quick test is when its not running right to turn on all your headlights, if it runs better, it is voltage related.

Should not run more then 14.5 volts , service manual can be found here:

I'm interested to know if the problem was corrected? What caused it?
