Sep 29, 2020

A Mikuni carb can be a great upgrade if you’re hot rodding your motorcycle. It has bigger inlets than a standard CV carb, and more air means more power. There’s also no butterfly in it and it’s not a vacuum-actuated system like a CV, so throttle response benefits as a result.

5 Reasons You Should Use a Mikuni HSR42 Carb

1. Air/Fuel screw is on air cleaner side, not manifold side like a CV carb, so it’s easier to adjust.

2. Easy-to-adjust idle, no screwdriver needed!

3. Can access main jet from the bottom of the carb without having to take float bowl off.

4. Throttle cable directly controls the slide so there’s no lag.

5. You can manually adjust the accelerator pump.
