Jetting

[PZEG300EX]

After breaking my leg into several pieces, healing and selling my DRZ400, I am now happily riding a 03' Honda 300EX that was in the family and barely used. I just put an FMF Powercore IV pipe on as well as a K & N Air Filter. I would also like to rejet but don't know which jets I should use. I live in Southern California and ride there and in Arizona at sea level. I do sometimes ride at about 2000 ft or so though. Any help on this would be great. I was going to just buy the FMF jetting kit for $59.95 but thought I would check in here first. Thanks!:)

I love my dynojet kit. The instructions and pictures are good that come with it too. They have a jet that is suppose to work for anything below 3000ft. so i'd go with that. What they reccomended for my HMF and K&N was spot on!
