Mikuni RS 38mm Carb Kit- Triumph 885cc Triple 900 Models

$1,620.00 AUD$1,695.00 AUD


Please select your carb set option with either 55mm intlets for use with POD’s and other filters found in this store or elsewhere, or otherwise with 58mm inlets for matching your OEM air-box where we install anodized alloy sleeves.

This Mikuni RS38 carburetor Kit is for high performance modified street engines where we recommend the 36’s for stock Triumph Adventurer, Thunderbird sport, Tiger, Trident 900 and other similar triples. This kit will breathe a whole new lease of life into your machine with even more top end 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 the following carb throat centre to centre spacing’s for direct fitment to Triumph triple models and with a total front to back measurement of 100mm will adapt to the stock air-box 58mm (for using PODs they can be supplied at 55mm), engine inlet rubbers (42mm) and throttle cables.

A= 88mm (spacing centre to centre between carb 1 & 2)
B= 88mm (spacing centre to centre between carb 2 & 3)
Pilot Jet: VM28/486-17.5, Needle: 9DZH1, Needle Jet: P-4 (568 Series), Main Jet: N100.604-120/130

A spare set of size 15 pilots are provided and may need fitting when using the stock air-box. Two spare sets of mains are also provided for WOT testing for confirming correct tune. Other than that bolt them on and hold on.

Of  the different versions of OEM carbs fitted to Triumphs, some stock throttle cables will connect to these carbs, where if you don’t have a return cable the factory recommends the fitment of one of our throttle and cable combo’s same as the one in the picture gallery being our road bike throttle and cable assembly (KRS-001) or otherwise a Quick action 1/4 turn throttle and cable kit (PPQA40K)
You can also buy separately either POD filters or Velocity stacks (only available in a set of 4) for racing, which have no form of filter in them (15, 30,50 and 75mm long). All these and other accessories are found in the main menu “RS Smoothbore Kits (multi Cylinde” option’s drop list- RS accessories.
