    swapped back to the old Mike's or WHOever muffs

    These headers don't have lower tabs but with the long mufflers I was able to hose clamp them tight to the factory header brackets, should be good.

    got the O2's in
    20190610_200211.jpg
    and the system fired up and worked, :smoke: Pretty much need the tank bag at this point, there are many "extra" feet of cable. I need to run a calibration yet and then I can set to doing some adjustments. As it is adjusting an idle mix screw made an instant difference on the AF reading. As I was suspecting, the needles are pretty good (on top clip) ie lean as I can go on them, and the mains are stinking rich. Plenty to do, :whistle:

    Dang Gary.... I can see tons of cool experiments with that setup.... tune for existing pipes and see what affect different muffies have. Same with the air filters.... tune for your pods and then see what the stock boxes do to AFR.... play with timing... the list goes on...
    Like Pete would say... "damnit... I'm comin' over." ;)

    This is all very cool. I understand that the o2 sensors can help tell you if you are running too rich or too lean, but how do you know what kind of baseline numbers you should be hitting?

    Bob, take 2 aspirins, and Google "stoichiometric ratio".

    The ideal stoichiometric ratio with good gasoline (octane) is 14.7:1.
    The ideal stoichiometric ratio with alcohol (ethanol) is 9:1.
    Expect something less than 14.7 with our modern gasohols.

    At low-throttle cruise speeds, carbureted intake manifold vacuum is high, and vaporization is nearly complete, expect high stoichiometric ratio.

    Full-throttle, high-rpms, carbureted intake manifold vacuum is low, time to vaporize is shorter, vaporization is incomplete, fuel droplets exist during combustion, incomplete combustion, expect lower/lowest stoichiometric ratios.

    Wow! This is complicated, I think I’ll go polish something. :unsure:

    They sure do look exactly like the mid 90s oem Ducati Monster CEV speedo, and Ducati Performance aftermarket CEV tach.

    Was doing jetting changing gas tanks so figured I'd swap in a an 82 breather, the old one had no restrictions and was blowing phlem like aqualung, going to see if I can plumb it Into the uni filters. 1560374038888-1894992228.jpg

    I also replaced my stock, twin outlet breather, with the later single outlet version, and hooked it up to this reed valve/check valve:
    https://www.heidentuning.com/xs650-...kcase-ventilation-valve-reed-type-detail.html
    It seems to work great, I just hooked a short, vertical hose to the reed valve outlet. So far, not a single oil drop has escaped, and no oil leaks either.
    The ideal solution would obviously be a vent housing with an integrated reed valve.....
