Rappy 660 Spit and Sputter
Well a few weeks back my rappy was running great, other than a bad starter clutch. Then the CDI box went on it and i had both of them replaced. Got it back and it ran good. Just a few days ago i was at my buddy house rompin in the woods and got a nice large stick jammed up in the left side. Hit so hard it knocked the carbs out of the rubber boots. well.... after a few backfires and flames, we found out this is what the problem was. So today i tore all the plastic off and re-seated the carbs and sealed them up. Its starts right up and idles fine. But at when held in neutral at higher RMP, mby 1/2 to 3/4 throttle, it spits and sputters.... ?!?! Itll drive ok, but definatly a loss of power, especially in top end. Also, it seems to heat up a LOT faster than it used to. Spark plug is light tan... very light... lean?? Im starting to learn some stuff, but still new at the quad thing. Just wish i didnt have a problem every week :-/ Any response appriciated.
P.S. .... any one want a 2002 660 raptor? :-P

well i had problems like your before. first time i had my jets clogged. so i think you might need to take apart your carbs and give them a good cleaning. i would also make sure your filters in your gas tank is not clogged.
second time is i had my reverse switch had mud and grim inside the rubber boot losing contact with the switch. this caused my 660 to spuder and spat.
i hope that helps ya

I'm going to guess that when the stick hit your carb boots it made a slight tear in it. Thats why it will idle fine but under acceleration there is more air/pressure flowing through the boots, therefore exposing the slight tear or crack. Allowing it suck more air than is needed and causing a lean condition. I would tear it down again and inspect the boots/manifold and make sure everything is clean and in good condition before re assembly.
