Question for the guru's out there. I have a 500 Rubicon and I just ordered a package from highlifter that includes a k/n air filter, exhaust and a jet kit. My problem is that after reading up on the jet kits that you are supposed to set them up in relation to altitude. I live at and do 50% of my riding at or around 2,000 ft. However, I do the other 50% at areas around 4,000 ft. How should I have this set up and will it affect my engine at either area. I'm not real familiar with working on atv's and will probably have it installed professionally but just wanted to ask some questions before I get this done. Thanks for any help.
