why did you richen your main jet? you need to lean it out, because you are above sea level. uhh... Most jetting is done at sea level (0m) and at about 23°. Try going back to the stock settings on jetting and see how the bike does :)

Oh and welcome to the forums

Too rich.

I'm also 600+ from sea level and have a high compression 2001 RM 250 with pipe/filter and 162 is plenty fat for a main. Pretty sure my pilot is 42and clip is leaner too.
