I think i may have figured out why it's rich. I pretty much finalized the jetting last winter, having bought the bike that summer. I jetted it by going larger till it was too rich then backing down a size. So it was on the edge of being rich. The plugs always looked good but It wasn't till this heat wave that i noticed the plugs getting sooty. My theory is based on what i've been told here before, which nis that in cold wether your bike runs leaner, hot, richer. So it would make sense that the very hot weather we've had put it over the edge and made it too rich. Coulda sworn i had 1 shim on the TBS needles, but i just went to check the slides and remove the shim and realized i had 2 shims. So i removed them all. The bike seems to run about the same,so i'll leave it there and see how it does. I think it'll be fine because the midrange is where i do most of my riding and thats where it was jetted very rich.
as to the vibes, i have yet to really give the front end a good going over. And as i said before i had a problem getting out one of the axl clamp bolts and had to really bang on the fork with an ez out. So i'll take the front end completely apart tomorrow and inspect the bearings and everything then put it back together. Could be the forks just have to be reset. The fact that i can recreate the cyclic vibration while coasting and then holding the revs at about 2 k, but it won't do it coasting at any speed higher than about 25 tells me it could well be a harmonic between the wheel and the engine at 2k RPMs. Or the rear, tho i've removed and checked that so many times i doubt it.
