03YZ450F I've ordered a Dr.D full exhaust should be here any day. I bought the bike in S.Cal it has stock jets in it as far as I know. I'm familiar with jetting bikes for street but I used a different company and the kits I ordered I could choose what size jets where in them. I'm pretty sure I'm going to have to re-jet once I put the bike back together and go ride. So I'm looking to order one of the jet kits from the TT store. My question is will these off the shelf kits have the proper jetting for my altitude and exhaust? I'll mostly be riding around 4000ft elevation. Also is any one better then the other? I see JD, FMF, and Moose kits.
