RS36-D3-KRS Mikuni Carb Kit | GSX-R 750 | GSX-R1100 | Suzuki GS 1000-1150 | Kawasaki Z900 | KZ 1000-1100 |

These Mikuni RS36-D3-K RS carbs will breathe a whole new lease of life into your machine with around a 25% increase in power, while 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. Unfortunately, as with many rebuilds nowadays, you only have the option in many cases of gambling with very poor quality aftermarket parts. Considering this, and if you intend 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 first check your carb spacing and carb sizes for compatibility. These are not suited for downdraft engines.

This Mikuni kit comes with the following carb center-to-center spacings for direct fitment to GSX-R 750 (to '90), GSX-R 1100 (to '90), Suzuki GS 1000-1150 (not the F touring model), Kawasaki Z900, and KZ 1000-1100.

Carb Spacing:

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

If the center spacing between your carbs #2 and 3 is 85mm, rather than the supplied 93mm, two of the outside carbs will need to be unbolted and then slid in 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 such as Kawasaki ZL1000 with the 85mm center 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.

Carb Dimensions for Motor and Air-Box Fitment Comparison:

• A = The OD at the motor end on 36’s is 42mm
• D = OD at the air-cleaner end is 55mm
• B = Front to back length is 100mm

Jet and Needle Specifications:

• Pilot Jet: VM28/486-17.5
• Needle: 9DZH5-50
• Needle Jet: P-4 (568 Series)
• Main Jet: N100.604-120/130

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