dynojet kit

[bdrue]

i dont know if anyone has seen this. i have a 400ex with a wb slip on, filter w/no lid choke mod, ported header... i bought the dynojet kit and followed stage 2 instructions. it told me to put in a 170 main, i did that and i checked the plug and its very light gray. and i had a 155 main before the exhaust and it was good tan brown color. does dynojet label the main differently? i might just go ahead anbd buy the oem jets seperately. what jet size should i buy from dealership, 160 or 165?

the dyno jets are different than the std keihin jets.for example a stock 140 main may be a 132 dyno jet main.go up on your main with the supplied dyno jets until you get a good plug reading.
