Mikuni's VM Series, round slide carburetors have proven themselves as the performance standard for use on single and multi-cylinder, motorcycle and ATV vehicles. They're perfect carbs for street riding, motocross, enduro and trail riding, as well as flat track and road racing. These carbs are designed to work on both 2-stroke and 4-stroke engines.

VM series carburetors offer a large selection of bore sizes for optimal fuel mixture and flow to match most engine modifications. A wide range of tuning components are available to allow precise fuel mixture metering in almost any application, at any throttle setting and under any riding condition.
