Description
This Mikuni TM40 Pumper Flatslide single carburetor conversion kit is for fitment to MuZ Skorpion 660 models which use a Yamaha 660 engine and are an impressive performance gain over the stock twin carb arrangement. These carbs are also a popular upgrade for Honda XR600, XR650, Suzuki DR650, Kawasaki KLR650, KTM, Yamaha 600 and 660, especially when you have worn out 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 flat spots. A wheel stand in at least an extra gear or two is usually the expected norm.
Kit Components: This kit is available in Basic form for use with a pod filter (not supplied). The kit comes with a Mikuni TM40-6 carb, a PA11 carbon fibre nylon printed two into one manifold with mounting hardware and gaskets, heavy duty rubber engine mounting sleeve with clamps, a 1/4 turn quick action throttle and a push/pull nylon lined cable set. There are jets fitted as well as spare main jets for WOT fine tuning. The carb comes with a rarely ever required cable choke with universal mounting bracket.
Fitting Tips: This kit requires cutting out the front of the air box to accommodate a large POD filter being either a 150mm long highest flowing Red Uni-Filter with sock or similar size cloth paper type POD. You’ll see in the Yamaha 600 Belgarda and Yamaha 350 kits we offer an air box connection kit with those carbs where you may be able to duplicate something similar for your bike. Please discuss this with us as some of the components we have may be of use. There are no gas tank modifications required with this kit.
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 worldwide.
The fuel consumption is way less but when comparing with the stock carbs, it all depends on how having a lot more power and torque effects your riding habits. If you can manage to back off and just have your bike perform at its present level you’ll be surprised by the fuel economy, but of course when the same amount of throttle twist becomes front wheel lifting, breaking traction action, well it’s hard to not want to go and play. If you have more horses in the paddock and you want them all to perform, you have to feed them more hay!
You will enjoy this new carb but do be sure to hold on tight on your first test ride as she may try to spit you off if you nail it to hard.
