just checked the compression on my rzr 1440 miles and only have 30 lbs pf compression. 1100 miles were in az this winter. i ran a k@n air filter. i cant believe this thing dusted itself, but it must be the case. what do you guys think.

 

My opinion on a K&N filter in dusty off road applications were never that good compared to a stock or Uni filter. No matter how they were maintained or even if they had covers, too much fine dirt could enter engines and eat up rings and cylinder bores. On a car,truck or motorcycles on street use they may be fine,but your bad luck doesn't change my opinion on them one bit on atvs or any off road machine.
