can someone tell me if these numbers sound correct for the jetting on a 1995 rm 250. i live in kansas. it has an fmf pipe and silencer. stock airbox and i run 32:1 maxima 927 or bel ray with 92 octane fuel. im not sure if these numbers are stock or not 3.8 i think this is for the needle? 48 pilot? and 168 main. the reason i ask is because it seems to run rich. im going to drop a tooth on the front sprocket and maybe add a 10 oz flywheel weight (as soon as someone on here sells me one for cheap) and steel clutch plates . then ill start looking at the plug and see what it needs. thanks guys.
