vm 29 mm vs rs 34 mm

for drag race only on my 810 cc gpz who can tell me what is the best carb set up is vm 29 vs rs 34.thats with milled ,ported head , megacycle cams.410" lift. dyna ignition.v&h pipe.

I have had both carbs on my Kz

I think both carbs are good. One of the stand out features of the RS-34 is the accelerator pump. The RS carbs are far superior in throttle response. The RS carbs also offer numinous different needles and needle profiles that the VM carbs don't.

The RS carbs are simple to do a needle or jet change while carbs are on the bike. I can change all 4 needles in 10 minuet's.

The RS will idle a bit higher. Do to the size of the main venture 34mm. As the VM29's idle about 200 rpm less do to the 5mm less opening, less effort to draw air though.

The VM29 carbs are a bit easier to tune in my experience.

i had a hard time getting it to idle without loading up and running rich .played around with the pilot fuel jet and the pilot air jet .do not remember the part #, s runs real good now great throttle response.
