TM40 Pumper Single Mikuni Flatslide Kit Yamaha XV Virago 1100 plus

  

This kit comes pre jetted for the XV1000 only. If you require the XV750 kit it is listed separately. Getting that custom look whilst going even faster has never been so easy, say goodbye to hard starting, hesitations and flatspots. This Mikuni TM40 pumper type carburetor, like the VM roundslide or TM38 non-pump options, will fix all your old stock carb issues and look great whilst also giving you a much bigger performance improvement over the others. The kit includes: A pre-jetted TM40 Mikuni Carburetor fitted with a side pull knob choke.

A Mikunioz designed cast two into one manifold with an enlarged mid manifold plenum area to better facilitate the fuel mixture between the cylinders. A 3rd heavy duty rubber flange is supplied for the manifold to Carb connection. A throttle and push/pull cable combo as pictured (820mm Long) plus also a purpose designed USA made Pancake Filter. Hardware includes all bolts and washers. No Air-filter support system is provided or should be needed, where if installing another heavier custom filter, the fabrication of a bracket or brackets will be required. 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. 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. 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. You will instantly experience better throttle response, improved acceleration, increased horsepower and torque. We have express options available for all our products also. Townsville to Brisbane 3 days, Townsville to North/Just South and West is usually 1-2 days.

NSW ACT & VIC 4-6 days, TAS & SA 4-8 days, WA & NT 8-12 days. NSW ACT & VIC 2 days, TAS & SA 2-3 days, WA & NT 3-4 days.

This is entirely out of our control if this occurs. THIS IS JUST PLAIN OLD COMMON SENSE. Please also note that international parcels HAVE to be signed for and all parcels whether domestic or international are fully insured.
