MIkuni VM36-4 Tuner Kit Yamaha SR400
Application: SR400 fitted with Mikuni VM36
Tuner jet kits consist of the suggested jets for changing that are not matching those factory fitted in the VM36-4, they include 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.
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
