Dave,
My jetting is all stock, per the manual, except the needle had a slightly different designation on the last 1 or 2 digits. I forget which, and I didn't write it down. At the time I checked, I think I dismissed the digits as being irrelevant. I don't think they were mentioned in theJust KDX jetting thread. Anyway, I'll get back with that info ASAP.
My bike was set up for desert, with a PC pipe originally. I suspect that the head may have been machined, because it gets a slight knock if I let my gas get a little stale.
I'm at sea level. What would the best starting point be for jetting, and which would be a good direction to head with the needle, if that's appropriate? The link you left doesn't get me anywhere, maybe its gone. I will read up on your blurb about jetting as well.
