The other night I had my 01 Summit 700 out... and it started running like it only had power to one cylinder... Check all DPM wires, and changed spark plugs.. nothing seem to change it... left it in a heated garage all night.. next morning it ran fine.... took it out again tonight.. ran like ass, idle is below 1000 rpm and will die if you don't keep reving it. Giving WOT from a stop, and track won't even spin... what could be the problem... or something I could try... thanks

I would say you have water in the fuel, and one carb is freezing up. Put a good amount of isopropyl alcohol in it, double the reccomended amount, and let it sitin the heated garage again. Then start it, put it outside, and put a tarp over the hood to hold the heat in. Keep an eye on the temp. gauge/light, and if it comes on, shit it off, or take it for a quick rip to cool it off.

Water was my first thought too. Pockets was correct, but I would pull the carbs and draing the float bowls. You may want to put a water absorberin your tank, there is likely some amount in there.
