the majority of us are running 40:1...and there's some running 50:1.
there's nothing wrong with running 32:1 as long as you jet to it, and stick to 32:1....don't ever change ratios unless you jet to those changes....or it could be a very costly mistake.

got any idea with mix ratio i should run with stock pilot and main jet size?
Foxx4Beaver:
I'm only assuming that 32:1 was the stock recommended ratio in '93...
you should write down exactly what jetting you currently have, then do a couple wide open throttle plug chops, and see how your current setup is...then make adjustments from there.
Danger4u2:
40:1

today i had a experience with the jetting wich just left me stunned, i was going to test the new clutch after all the work i've put in to the bike and found that the engine ratteld maybe even pinged (im not sure how that sounds) but the weird part is that there was excesive amout of smoke, even more that what used to be with richer jetting in warmer weahter!, i currently have 55 pilot and 165 main wheater today was 14-17 celcius a bit humid as it has been raining, i recently installed a fmf gnarly desert pipe with powercore scilencer, so what i can't understand is how come the leaner jetting in colder weahter make it seem like it's running rich and lean at the same time?
sandblaster:
What needle are you running and what is the position of the clip?
Something else I'm curious about, did this bike sit for a while before you started riding it?
