Bonneville America Forums Forums Technical Forums Performance Mods single carb for parallel twins

Partly to get rid of the variable venturi, and needles, they react slower.
To use the the booster jet system better atomization of the fuel and instant reaction time.
The vacuum does not have to move a spring resisting slide up to move a needle up to open up the jett more to allow more fuel.
With the patented booster jet the more air flow the more fuel the only mechanical devices involved is the throttle opening the butterfly.
The carb engineer has had a lot of success with this on the race track with Vtwins. Now we are going to try it on ours and see what happens.
