VM36 Twin Mikuni Roundslide Carb Kit Yamaha XV Virago 750 thru 1100

Description

Going fast has never been so easy, say goodbye to hard starting, hesitations and flatspots.  These Mikuni VM36 roundslide type carburetors fix all your old stock carb issues and look great.

The kit includes: Two pre-jetted VM36 Mikuni Carburetors. A pair of  CNC machined and anodized alloy spacers and mikuni rubber mounting flanges which move the new Mikuni VM36’s back into position so as to mate up with your stock air boots. A nylon lined 2-1 throttle cable with splitter box to connect to your stock throttle. This cable measures 950mm long and as many of these bikes are now custom modified,  if you do advise at the time of ordering that you require a different end fitting or length (1050mm max to as short as you specify) we can in most cases do the changes at no cost. This only applies to a request at the time of purchase and also do be aware that some aftermarket throttles may not manage to fully open the slides on these carbs where generally some throttle tube modification will remedy this.

The chokes work independently on each carb and can be awkward to get at depending on the gas tank but never needed as generally over fuel if turned on. Normally just start, feather the throttle for 15 seconds or so and you’re right to go as per the customers review. We do sell knob chokes and cable choke kits both found in the VM36 page, selected from the drop list under the main menu “VM Roundslide Carbs” option. You can also bend the tag on the lever choke enabling you to rotate the lever 180 degrees if feeling you need the choke circuit or to run a test.

FUEL PUMP MODELS: With an 1100 or others if you still use the fuel pump , sometimes you may encounter leaking out the overflow at idle.The float height is factory set and will be correct. This is caused by the pressure from your pump which is popping off the needle and seat. Adjusting float height 2mm may work but usually not. Otherwise there are two options:

1) install an extra “T” on the carb supply line so as to then run a return line to the tank. This line needs to be plugged with a restrictor so as to work as a pressure relief whilst to not take flow preference away from the carbs. Usually a 1mm hole in a restriction plug fitted inside the new line is good.

2) replace the 3.3 needle and seats with the 2.0mm options from the VM28/511 option drop list found in the main menu needle & Seats page. There is a video in our “How to Videos” main menu option “leaking needle and seat causes and removal”, watch the removal process for your carb type if changing seats.

In “How to videos” page the VM carb tune check also relates to the TM carbs and we do recommend you also watch the cable attachment and carb sync video

Our technicians can guide you through any after sales carb related inquiry.

The jets to make this carb operate on Yamaha XV models have been fitted and there are spares for fine tuning the main jet circuit doing WOT tests. Climate, altitude and fuel density from different octane fuels all have varying effects on final fine tuning as does cam, exhaust and cylinder head porting etc. For this reason, we have included what we have found to be a range of jets to allow you to tune to most variables using Australian fuels.

At Mikunioz, for the last 30 years, we have been constantly checking and where necessary upgrading our jetting specs as fuel quality changes. Regular fuel in the USA is 85 octane or 91 in their premium brands which have numerous additives and blends added (basically smells and drys like wood varnish) which results in a totally different jetting spec and product performance.This carb as supplied from the factory will never work on this bike and requires a total re-jet which is done in house at Mikunioz prior to delivery with jets to suit your location anywhere in the world.

You will instantly experience better throttle response, improved acceleration, increased horsepower and torque.
