    Thanks for the info bigfoot i will try pulling jets tommorrow and installing the 185s .I sure hope this is what my problem is as it smokes way to much at idle and when you first gun it it seems a little dead and leaves a nice thick cloud of smoke as others i have rode with say that when they follow me they can smell raw fuelAlso forgot to mention that it has a psi can and factory altitude compensators ,dont know if this would make any difference

    You may have answered your own question..... Altitude compensator could very well be the culprit. Check oil pump setting also.

    The ACCS has been known to fail, if thats the case, rip it out and install a vari-flow instead.

    i wouldn't even bother with the vari flow. 9 times out of ten it hardly works anyways. Does it have a stock pipe? if not remember an after market pipe will lean things out.

    On the 2000/600/rmk the jetting was updated to this.

    keihin pwk 39 with ACCS is as follows.
    main jet (175)
    pilot jet (48)
    jet needle (r1368j-3)
    needle jet (2.9x4.6x1.5mm fixed)
    cutaway (6.0 notched)
    air screw (1.0).
    For( 0-12000ft) the jetting is said to be (175 main)-(#3 CLIP POS.). Also, check your (choke) plunger seats. If these are cracked or damaged it will cause the same problems you are having. GOOD LUCK

    Powder pusher was asking about a 1999 600 in his original post and thread I believe.

    Yes I know, it problably was updated to the new settings for the 2000 model year, He should go to his dealer to make sure. PS, I hope his dealer knows what they are doing, I have seen so many shoty outfits.
