VM Roundslide Carburetors
These are the most popular high performance singles carburetor in the sport of motorcycling. Mikuni’s VM series round slide single Carburetors
have proven themselves as the performance standard for use in any single cylinder motorcycle or ATV applications for motocross, enduro and
trail riding, to flat track racing and road racing on both 2-stroke and 4-stroke engines.
Performance features for the VM Series Carburetors include a large selection of bore sizes for increased fuel mixture flow to match engine
modifications. The VM Series offers a wide range of tuning components to allow precise fuel mixture metering in any application, at any throttle
setting, under any riding condition. VM Series Carburetors are sold pre-jetted. (see Standard Jetting Specifications below)
Special Jetting also available, see next page.
Please Note:
Changes and jetting modifications are for use only on racing machines or similar off-road vehicles where pollution laws are not in
effect. Not legal for vehicles operated on public highways in the State of California or other areas where similar pollution laws may apply.
