    It is kind of an odd response.

    I had to buy a r-0 needle jet because none of the bikes I got had one and some were supposed to come that way. The r-0 needle is as of yet untested. I have (on a six speed)the 430 cylinder and piston with a 500 head and a stock 430 exhaust from which that cylinder and piston came off an auto. I have the needle (the one you put in the post 6DH20 ) in one of the extreme positions, I found it that way this spring and came to the conclusion (apparently same as before) after moving it around that was best. I think the leanest one. R-2 needle jet. Clearly there is much more empty space in the crank cavity (and the head difference) on the auto but it might count.

    I also might note that I seem to have settled on the 3.0 slide or a 2.5 slide modified and re marked as 3.0 which has been discussed on here for that type of carburetor in probably a different model.

    I never messed with my 86 430 auto just ran it like the guy I bought it from did.

    My more advanced bike has the keihin pwk 39 which is pretty easy for me to figure out what does what with the available literature. I really don't know what to make of the fuel around here lately stuff from steel tanks on my brand x bikes seems to turn black.

    My father set up his 1988 430 AE this way and never missed a beat. I don't know if it'll work for yours as it's an earlier model but I hope it helps.

    I have put this tuning ( under) last week and it seems to work .
    I think my R0 needle jet was too small.
    Thanks
