So im jetting my bike today and i warmed it up then changed the plug and ran it quit hard through 1st the 5th and cut it checked the plug and its white on the inside but has a very mocha dark color around the threads and rim of the plug im scared to ride it to hard for to long of the chance of it leaning out but it smokes blue while its at idle im wondering how long i should run it to do a plug test

thx

You are asking how to do a wide open plug chop to read the main? You need to start on the pilot circuit. http://www.dirtrider.net/forums3/showthread.php?t=172481&highlight=Spanky's+jetting+guide, http://www.dirtrider.net/forums3/showthread.php?t=92818

thx for the reply yeah on the bottom part under the insilator it was mocha color just wondering if its wierd that its smokes only when it idles and i rev it up hard i think i might have the jetting as good as it gets

Could be? Float valve. The 125? 1986? Replace the float valve and seat, if applicable. Mocha is a food, not a color? Dark is rich, white is lean. The burn ring is at the top of the insulator, you either need to cut the threads off or buy a special viewer to read it properly. Should be in the second link from my earlier post?
