Description
THIS KIT INCLUDES: ONE SET OF MIKUNI RS34 CARBS, 4 x ENGINE MOUNT STUB FLANGES WITH RUBBER BOOTS AND CLAMPS PLUS 4 x POD FILTERS:
These Mikuni RS34-D21-K RS carbs will breath a whole new lease of life into your Kawasaki KZ750/650 machine with around a 25% increase in power, whilst making it perform and operate as it should. No more flat spots or hesitations just way more smooth controllable power.
You will very quickly realize that the expense of a rebuild of your old worn OEM Kawasaki KZ750, GPZ750 or KZ650 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.
This Kit is for fitment to Kawasaki GPZ750, KZ750 and KZ650 models where not requiring our push pull throttle and cable combo, which can be bought separately. The stock 650 carbs have a 35mm outside diameter on the motor side outlets which won’t accommodate the 40mm outlets on these Mikuni RS34’s, and the cam chain adjuster on the 750 motor fouls on the RS carbs if using the OEM motor mount flanges, hence both require our mounting flange set. This Mikuni RS34 Kit includes the bank of 4 Mikuni RS carbs, jetted and ready to ride with usually no tuning at all required, 4 new silver anodized stub flanges (tapering down to 28mm for the 650 engines and 32 ID for the 750’s), for use with Allen type socket head screws not supplied, where do include gaskets, rubber boots and clamps. As these carbs are pushed back with the new longer engine mounts negating the use of the standard air-box, there’s also 4 cloth/paper dry type automotive pod filters included.
Check your carb spacing as per the picture and if not 77-93-77 as supplied here please contact our office to discuss alternatives.
Pilot Jet: VM28/486-17.5, Needle: 9DZH1, Needle Jet: P-4 (568 Series), Main Jet: N100.604-115

Andy Hollingdale –
I have just fitted this kit to my 1983 Gpz750a after being fed up of chasing second hand carbs bits across the internet. From the very first email MikuniOz where first rate. They guided me through all the options to make sure the set up suited my bike. The kit was “plug and play” and the improvement is fantastic, smooth power delivery with increased performance. and easy starting. I had the kit delivered to Scotland and the process was very simple you pay VAT, a courier handling charge and a very small(1%) import duty. Took just under 2 weeks for me but you can track the package at every step. I consider this the best improvement you can make to an old bike
