Yamaha SR TT XT 500 Mikuni TM38 Flatslide Non-Pumper Carb Kit

$425.00 AUD

SKU: TM38YAMXT500-K Category:


The Mikuni TM38 Non Pump type TM Flatslide carburetor for your Yamaha SR TT or XT 500 is a step up in performance over the VM Roundslide Mikuni options where the cost of a TM Pumper carb can’t be justified for what ever reason. These have for decades been the economical replacement carb of choice for Honda XR600 and XR650 riders who have worn out their OEM carbs or are just over some of their inherent problems. All this means getting the full enjoyment out of your motorcycle has never been so easy, say goodbye to hard starting, hesitations and flatspots.  These Mikuni carburetors like the VM will not adapt to your stock air-box where the separate purchase of a Paper or foam POD air-filter is required. The kit comes with a new rubber engine mounting flange to move the carb closer to the cylinder head plus a 1/4 turn quick action throttle and a nylon lined cable with a 90 degree lower fitting for the tight clearance on some models. There are jets provided that must be changed as well as spares for fine tuning. 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.

You will instantly experience better throttle response, improved acceleration and performance. If chasing optimum performance check out our TM36 or TM40 Pumper Carb options.


If wishing to modify or use your existing cables or mounting flange to suit the Mikuni TM38  you can purchase the carburetor, tuner jet kit and or what ever other components you want individually by following the directions below.

On the main menu to the left of the page, hover over the carb listing for TM Carbs (non Pump) and then select TM38 from the drop down list. When clicking on any individual size Mikuni carb from the drop down list it will put you into a page showing not only the Mikuni carb itself but also any items relevant to that carb, being Mikuni jets, Mikuni flanges, Mikuni carb tuner kits, Mikuni cables , Mikuni throttles, Mikuni air-cleaners and a range of Mikuni carb to OEM air box adaptors etc to also suit. This also makes alternate jet selection easy for you if you have your own spec as only the type jets for that particular carb are shown.
Click on the carb itself (TM38-86) if wanting to view the full details and or to make your purchase. Then back arrow back in the carbs main page and go into the tuner kits, which show in the sales drop down list the jetting kits we have for confirmed suitable engines for that particular carb. Again thoroughly read the tuner kit description.
