ok my brother has an 09 rmk 700 with 3500 miles on it and it has a low idle and when you give the throttle a quick "snap", it fouls the plugs. I figured fuel filter and have a new one coming and going to try, but has anyone else have any issues like this and if so want was the solution.

Thanks ahead of time
Josh

My money is definitely on the TPS (throttle position sensor) needing to be re-calibrated.... it can cause all sorts of issues such as the ones you are having. Polaris CFI's are notorious for these getting 'bumped'.

Also try switching from the factory Champion RN57YCC to NGK BPR9ES... my buddy fouled 2 good sets of Champions in 15 minutes 1 time including numerous sets on many trips before that and after he switched to NGK he has only fouled 1 set in the last 3 years.

I would check the oil pump and the reeds also. I've had to do both because I was fouling plugs.
