i just put a k and n filter on my quad and took out the baffel from the stock exhaust and the header glows red so i know i need to jet my quad. so i was wondering if this is a real pain on the wolverine or if its no big deal, like is there any drilling involved. thanks for your help.

 

does it only happen when u run wide open down the road for a while or does it happen in the mud also?
