Description

Our VM34 Carbs (VM34-168 & VM34-275) come jetted with Pilot 35, Jet Needle 6DH4, Needle Jet 159 series size Q-2, main Jet 260,  Air Jet 2.0 and a 2.5 slide which if wanting a slide change needs to be made as a separate purchase. This set of Jets presumes you already have this carb with these jets. The picture shows the replacements for these that are being supplied.

This Tuner jet kit consist of the suggested jets for changing that are not matching those factory fitted in the VM34-168 or VM34-275, it also includes an extra one size up and one size down main jet for tuning the main circuit due to fuel quality variations, altitude and climate. Testing and conformation of correct main circuit jetting can only be done by physically changing jets and WOT testing. Only two main jets are supplied in kits where the one in the carb comes into the mix.

These tuner jet sets have been determined from thirty years of experience, customer feedback, plus research and development as the Australian Mikuni distributor. From time to time these may not be exactly right for every engine, usually due to changes to porting, compression or numerous other things that contribute to the requirement for additional fine tuning but as a rule our kits are spot on or a very close and useful starting point, but we give no guarantees and sorry do not release kit details or jet size information. If you have your own spec simply purchase the carb and buy any other required jets from the jet pages. This also applies to replacing jets in other VM34’s as the 159 series needle jet and others items may not match and fit.

Keep in mind that these are suggested specs, and all tuning procedures, as found in our Tuning Tips section or watching the “How to Video” at the top of the menu, must be adhered to for the confirmation of any supplied jet’s compatibility with your engine.
