Description

These Mikuni RS34-D21-K RS carbs will breath a whole new lease of life into your machine with around a 25% increase in power,  whilst making it perform and operate as it should.

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 also 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 following carb centre to centre spacings for direct fitment to GSX-600 ’88, GSX-R 750 to’90, Suzuki GS 750 ALL (not the F touring models), Kawasaki KZ 750 Z900 KZ1000 etc

Check your carb spacing as per the picture and if not 77-93-77 as supplied here but only requiring a 77-85-77 spacing adjustment this can be either done by yourself or we can do it by selecting the re-spacing labour option for $88 in the RS carbs accessories page

A= 77mm (spacing centre to centre between carb 1 & 2)
B= 93 (carb 2 & 3) see note below if different
C=77mm (carb 3 & 4)

If the centre spacing between the centres of your carbs #2 and 3 is 85mm, rather than the as supplied 93mm, two of the outside carbs will need to be unbolted and then slid in so as to align with the second set of provided securing points and then re-fixed. Due to limited demand for these  carbs to suit 86-87 Yamaha FJ 1100 and 1200 engines along with some other applications with the 85mm centre measurement the factory no longer markets them assembled in this configuration thus requiring you the end user to make the adjustment and then re-synchronize the slides.

The carb dimensions for motor and air-box fitment comparison are listed below and reference to the dimensions picture. If these dimensions are not matching your cabs we have new engine mounting flanges and or sleeves for up sizing, down sizing and increasing the carbs front to back length to match most OEM items. When purchased in conjunction with a carb kit, sleeve to carb fitment is complimentary. All sleeves along with any other accessories are found in the “RS carb Accessories” pages located in the main menu “RS Smoothbore Kits” option’s drop list.

A= The OD at the motor end on 34’s is 40mm
D= OD at the air-cleaner end is 55mm
B= Front to back length is 100mm

Pilot Jet: VM28/486-17.5, Needle: 9DZH1, Needle Jet: P-4 (568 Series), Main Jet: N100.604-115

We have twin throttle and cable assemblies available
Velocity stacks which have no form of filter in them (15, 30,50 and 75mm long) for racing

    I fitted these to my 1976 kz1000 and can’t believe the difference they have made. I spent many hours and $ on the original carbys and it still ran like shit. I bolted the RS34’s on and she fired first kick. I didn’t even need to tune them the motor ran sweet right up to the redline smooth as. I’m rapt in the performance especially since this is a tired old motor, it’s now got a new lease of life!
