Kit Note: This kit comes pre jetted with all supporting mods (As Pictured) to suit the Yamaha Virago 750 up to 1000cc. This kit comes with an oval pod in black, if black is out of stock, you will be sent whatever colour is available. Please read the description below carefully and if you have the fuel pump model or a different size motor to this you will need a different kit which is listed separately.

Getting that older 70’s custom look whilst going even faster has never been so easy, say goodbye to hard starting, hesitations and flatspots.  This VM38 Mikuni roundslide carb, will fix all your old stock carb issues and look great. Even bigger performance improvements can be gained using our TM40 or TM42 Pumper kits.

The kit includes: A pre-jetted VM38 Mikuni Carburetor. A Mikunioz designed cast two into one manifold with an enlarged mid manifold plenum area to better facilitate the fuel mixture between the cylinders. To allow for a wider manifold with better holding grip whilst still isolating the heat from the fuel delivery system, the OEM carb rubber mounting flanges are replaced with 2x shorter  Mikuni heavy duty flanges designed and made for the Harley market. A 3rd heavy duty rubber flange is supplied for the manifold to Carb connection. A basic Oval POD type air filter is included at no cost to either supply budget filtration or make do if waiting to fabricate or mate up your own custom filter assembly. A nylon lined throttle cable to connect to your stock throttle. This cable measures 950mm long with a low profile 90 degree carb top fitting. 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 to suit another throttle type or length (1050mm max reducing to any shorter length requested) 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. Hardware includes all bolts, washers and 1x 4mm Vacuum hose tail requiring a 5/32″ hole drilled to locate in a location of your choosing if required. No fuel or vacuum lines are provided.

No Air-filter support system is provided where if installing a heavier custom unit, the fabrication of a bracket or brackets may be required. You will notice that this VM carb does have a very long filter side spigot which if wanting to pull the filter closer back into the motor, can be shortened by up to 20mm. If doing so you must carefully mask off the carb and vacuum away any filings when finished.

The choke is usually never needed in most climates. Normally just start, feather the throttle for 15 seconds or so and you’re right to go.

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 fuels.

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 1.8mm option in the VM28/511 type available through Mikunioz direct. If you would like to buy the kit with these needle and seats already installed, the kit is listed separately on ebay. There is a video in our “Mikunioz YouTube channel" on leaking needle and seat causes and removal”, watch the removal process for your carb type if changing seats.

On the same YouTube channel check out 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.

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.
