Description

This Mikuni RS40 carburetor Kit is for direct fitment to most Larger GSXR Water/Liquid Cooled engines. They will breathe a whole new lease of life into your machine 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 it makes good sense to retire your OEM carbs into the cupboard and step up to a set of RS’s.

Before rushing in and ordering please firstly check your carb spacing and carbie sizes for compatibility. These are not suited for downdraft engines.

This Mikuni kit comes with the carb  throttle port  center to center spacing’s listed below for direct fitment to Suzuki GSXR WC Liquid Cooled Engines.

A= 85mm (spacing center to center between carb 1 & 2)
B= 90mm (carb 2 & 3)
C= 85mm (carb 3 & 4)

The carb total front to back length of 100 thru 103mm replaces OEM carbs measuring 96 thru 100mm and comes with either a 55mm inlet outside diameter for use with POD filters or velocity stacks or with fitted sleeves increasing the inlet diameter to 58mm for standard air-box compatibility. The carb outlet diameter at the motor end is 44, where your engine will be 46mm making it impossible to makr a 1mm thick sleeve with indents ao all thats required is for you to tension your rubbers a bit tighter down onto the carbs. Select from the options in the purchase drop list.

On some engines the side plate is in the way of the new choke knob and needs some material removed for clearance when engaging the enrichener, as shown in the picture gallery.

All sleeves are CNC machined, silver anodized and permanently set in place using 620 Loctite. These RS carbs have been re-spaced using new stainless steel throttle and choke shafts along with plated metal upper and lower support brackets for maximum strength and rigidity.

PLEASE SELECT YOUR CARBURETOR AIR-FILTER AND ENGINE END, OUTLET SPIGOT DIAMETERS WHEN PURCHASING 

Pilot Jet: VM28/486-17.5, Needle: 9DCHY10-99, Needle Jet: Y-6 (568 Series), Main Jet: N100.604-140

Your stock throttle cables will match to these carbs, 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 which have no form of filter in them (15, 30,50 and 75mm long) for racing.
