I am close to purchasing this bike. My understanding is that it is jetted very lean from the factory and I don't want to break it in that way. But of course, I want to ride it as soon as I get it, so I'd like to have the correct needle and jets on hand to get it set up better for break-in purposes. Can you recommend an initial carb setup? According to the Owner's Manual (on-line), it says it comes configured as so: Keihin FCR-MX 3900E main: 178 jet needle: OBDVR idling jet: 42 main air jet: 200 idling air jet: 100 needle position: 3rd from top mixture screw open: 1.25 My elevation is near sea level (central North Carolina). I'm hoping you can recommend an appropriate set up so I can have the parts to do the job handy when I get the bike home. I'm not opposed to a JD jet kit, but if I can do the job for the price of a needle and a few jets, that would make me happy.
