Suits Mikuni BDST 38 fitted OEM to Ducati, Yamaha TDM850 and numerous other BDST applications where a direct comparison can be confirmed.

This Mikuni BDST Needle valve seat comes with a 1.7mm inlet hole diameter. This size is an actual mm measurement of the diameter of the hole itself and usually is stamped on the end of the seat. If converting from gravity feed fuel to pumped, down sizing this hole size eliminates the risk of seat pop off and flooding. For methanol go as big as you can.

Some seats may not be found in our listings and these will only be available from the OEM motorcycle manufacturer for whom they will have been specially made. If unsure call or email.

The clips on the needles are there for ease of assembly and have no bearing on the actual function. Some seats may or may not have an adapter on top for fitting a screen filter which can easily be replace by using an inline filter on the main supply hose.
