Go figure, more jeting dialogue! After reading all the threads for months and seeing activities like drilling out ET's, gray wires, BK mods, EK* needles and OBELN needles, I'm in need of therapy! Anyway, it looks like it might cool off here this year (finally!) and I'll have some time on my hands to tinker so I thought perhaps I could con someone into summarizing all the experimentation for my application: 99 WR400 modified throttle stop, FMF Power Core IV (stock header) That's it (engine wise). Still has WR cam timing, octopus, etc. Elevation: Approx 300' (Maybe up to 1500' if I go out of state). What are the latest recommended baseline jetting specs, along with mods done using those settings? (YZ timing, gray wire disconnected, etc.) And would anyone (JD? ) take it upon themselves to make a summary table of this info and post it in the Technical section so that dweebs like myself won't continue to ask what needle, MJ, etc., should I start with? Thanks guys and keep up the good work!
