Going fast has never been so easy, say goodbye to hard starting, hesitations and flat spots. These Mikuni TM38 non pumper type carburetors, like the VM round slides, will fix all your old stock carb issues and look great whilst also giving you an even bigger performance improvement over the VM.The kit includes: Two pre-jetted TM38 Mikuni Carburetors. A pair of new CNC machined and anodized alloy stub flanges with proper locking in rubber boots and stainless-steel clamps which move the new Mikuni TM38'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 reducing to any shorter length requested) we can in most cases do the changes at no cost. 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 in most climates. Normally just start, feather the throttle for 15 seconds or so and you're right to go. We do sell cable choke kits found in the TM38 page, selected from the drop list under the main menu "TM Flat slide carbs (non-accel pump)" option.
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.
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. 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 dry's 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.
