Most popular high performance single carbs in the sport of motorcycling. Features include a large selection of bore sizes to match engine modifications, plus a wide range of tuning components to allow precise fuel mixture metering in any application. TM SERIES FLAT SLIDES TM carburetor provides significant performance improvements over older design round slide carburetors. Air flows faster and smoother through the TM Series venturi due to the flat slide configuration and the jet blocks which help create a smooth bore effect. The high velocity of the air flow means a stronger vacuum at the needle jet needle, providing more precise metering and better throttle response. POWER JET KITS The TM Series bodies are designed to accept Power Jet Kits. Power Jet Kits are usually used on carburetors in two-stroke engine applications to prevent leaning out during extended full-throttle running. For Power Jet Kits see below.
