Mikuni TM40-6 40mm TM flat slide carburetor w/accelerator pump. Please refer to the Compatibility Tab above for complete fitment information. TM Series Carburetors provide 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 smoothbore effect. The high velocity of the air flow means a stronger vacuum at the needle jet, providing more precise metering and better throttle response. Uses standard VM pilot, main and air jets. Comes with built-in location for power jet.
