alright man. i have getting some vm36 tuned in ill see how they do but if i decide to switch over to these carbs, ill be well informed. thanks for the info
Setup:
- Stock bore
- Light porting
- 1 1/2 turns on the mixture screw
- #40 pilot
- #140 main
- HKJ needle 4th slot from top
- gutted Dyna mufflers
- 35mm ID 2-to-2 pipes
- Pipercross foam filters
- 50mm piece of 50mm ID rubber hose acting as "velocity stack"
Proper test run today. 20km's. Still need to check float levels, sync and adjust mixtures.
Still some hesitation when cruising with very small throttle opening (about the first 1/8th of the throttle travel). Seems it's not really sure if it should go or not. Little black smoke when revving the bike in neutral. Plugs black and sooty. Maybe the #40 pilot is just too big.
Fast WOT acceleration was great! No hesitation or surging just nice steady pull.

Will test drive tomorrow.
Mrriggs, man, I felt guilty for letting my bike get dirty, you make me feel a lot better
Can you share a bit more about your experiment? Curious minds...
Cheers
I ended up buying some tops from a ZX750, assuming they were stamped steel. I was surprised to find that they are stamped aluminum. These things are light, less than an ounce each. Almost half the weight of the plastic caps.
I reckon those flanges look really delicate and likely to distort if you're not careful. You'll have to have a soft touch with the screwdriver. I'd always be thinking, "Are the screws tight enough?" or "Are the screws too tight". Me, I'll stick to the black plastic ones - nice and rigid and with locating spigots. But as they say, "Y'pays y'money, y'takes y'choice!"
I had that same thought originally but, after putting them on, I realize that the extra thickness is not needed.
The flanges are flat on the carb body, metal to metal. There is no gasket or diaphragm between them that can squish down and allow the flanges to distort.
Hey now, I wash this thing once a year whether it needs it or not.
