Mikuni Oz Product Description

PLEASE NOTE: This kit comes with a set of Triple RS36 Carburetors only. There is 3 other variations of this kit available and they are all separate listings.

This Mikuni RS36 carburetor Kit will breathe a whole new lease of life into your machine with an up to 25% increase in power, whilst making it perform and operate as it should with no hesitations or flat spots.

You will very quickly realize that the expense of a rebuild of your old worn OEM carbs can far exceed the cost of these new units and unfortunately as with many rebuilds now days you only have the option in many cases of gambling with very poor quality aftermarket parts. Considering this and if intending to ride and enjoy your motorcycle for years to come, it makes good sense to retire your OEM carbs into the cupboard and step up to a set of RS’s, the improvement will be very impressive.

Before rushing in and ordering please firstly check your carb spacing and carbie sizes for compatibility.

These carbs measure 100mm front to back length and 55mm OD at the air-filter inlet end and 42mm OD at the outlet, they are a direct fit if replacing Mikuni CV Carbs. The OEM throttle cables on XV Yamaha Virago’s fitted with Mikuni CV’s will fit these RS carbs where models that have Hitachi carbs, will not. When replacing Hitachi carbs, you have the option of having your cables modified elsewhere to fit or you can take the carb option supplied with our accessory throttle and cable combo. The Hitachi carbs are also around 16mm longer than the CV’s and the new RS Carbs, where if wanting to retain your stock air-box we can fit 16mm extenders to your new carb set. Another popular remedy for this is using POD’s where these are found in the “RS carb accessories” page found in the main menu “RS Smoothbore Kits multi Cylinder” drop list.


This Mikuni kit comes with the following carb throat centre to centre spacing’s for direct fitment to Yamaha  XS750 and XS850 triple models and others with simular carb spacing measurements.

A= 90mm (spacing centre to centre between carb 1 & 2)

B= 90mm (spacing centre to centre between carb 2 & 3)

Pilot Jet: VM28/486-17.5, Needle: 9DZH1, Needle Jet: P-4 (568 Series), Main Jet: N100.604-120/130


A spare set of size 15 pilots are provided and may need fitting when using the stock air-box. Two spare sets of mains are also provided for WOT testing for confirming correct tune. Other than that bolt them on and hold on.

You can also buy separately either POD filters or Velocity stacks for racing, which have no form of filter in them (15, 30,50 and 75mm long).
