Mikuni TM28 Spigot Mod for RD350 Intake Manifolds




Just like the title says, this modification is for the use of the Mikuni TM28 flatslide carburettor on the RD350. The stock manifolds are more than a little loose on the TM28 spigots and it’s not worth the risk of an air leak. With this modification a larger O.D. spigot outlet is fitted to the carburetors. The process involves machining the stock spigot to a smaller O.D. and then pressing the new custom machined spigot on.

This process requires that the TM28’s are shipped to CL MotoTech for machining.

Note: This process modifies the carburetors permanently.
