Please note: 

This kit comes pre jetted for the 865cc and is a set of twin carburetors only. If you require the 760cc kit it is listed separately.

This Mikuni RS40 carburetor Kit will breathe a whole new lease of life into your Triumph America, Bonneville, Scrambler 900, Speedmaster and Thruxton 900 twins with an up to 25% increase in power, whilst making it perform and operate as it should with no hesitations or flat spots.

You will very quickly realize that the expense of a rebuild of your old worn OEM carbs can far exceed the cost of these new units and unfortunately as with many rebuilds now days you only have the option in many cases of gambling with very poor quality aftermarket parts. Considering this and if intending to ride and enjoy your motorcycle for years to come, it makes good sense to retire your OEM carbs into the cupboard and step up to a set of RS’s, the improvement will be very impressive.

Before rushing in and ordering please firstly check your carb spacing and carbie sizes for compatibility.

This Mikuni kit comes with a 133mm carb throat centre to centre spacing between carb 1 & 2 for direct fitment to Triumph 790cc and 865cc twin models and at a 100mm back to front total length will adapt to the stock air-box (55mm dia.) , engine inlet rubbers (42mm) and throttle cables.

These carbs are supplied with jetting to suit your Triumph and will rarely need further tuning other than with the supplied two spare sets of mains for WOT testing for confirming correct tune. Simply bolt them on and hold on. The fitment of a performance clutch and spring kit is often required to keep up with the new found power. Removal of the sensor on the earlier models has no effect on performance or operation.

Your stock throttle cables will on most models connect to these carbs (note in the picture how the OEM cables must be laid over to the center and then pass up over the RH side of the rocker box), where we also have available in the RS accessories page either our road bike throttle and cable assembly (KRS-001) or a Quick action 1/4 turn throttle and cable kit (PPQA40K)

You can also buy separately either POD filters or Velocity stacks for racing, which have no form of filter in them (15, 30,50 and 75mm long).
