Typically used on high performance 250cc Two Stroke engines.

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.

Questions & Answers

What is the needle jet ID for the TMX38 or what is its measured inner diameter (using a digital caliper)?

The TMX has a fixed needle jet which cannot be removed without damaging the carburetor. So getting an accurate measurement is difficult.
Measuring the base of the needle jet where the main jet screws in, the ID is just under 5mm (approximately 4.75mm) which is also the OD of threads on the main jet.
