hello, I am new here so please bare with me for a bit. I have a 2007 700 XP. I can be driving down the trail fine and all at once i loose power, like fan kicking on or something trying to come on. it lasts for 1-4 sec. then back to full power. It is notice able when hitting dirt roads running about 20mph, lights will dim, then bam...back running good. sometimes it will run good for however long sometimes it will jump back and forth the entire time running. anyone, any ideas I can look for

Check you stator wires to see if they are rubbing on the case. I've seen them short out there several times.

Ditto on what Curt says ^ ^ ^. If that isn't the problem, it's probably a chafed wire somewhere! Can be a real bugger to find. Also check your wires for a weak spot - they are notorious for breaking inside the insulation - gotta 'feel' for it.

does the battery light come on when it starts running poor?

Like Curt said, I'll look for chaffed stator wires first... after that my suspicions would lean toward the voltage regulator.
