Description
This Mikuni RS34 carburetor Kit suits Honda CB750 Four Single Overhead Cam K Models. They will breathe a whole new lease of life into your machine with an up to and over a 25% increase in power and a huge WOW factor, whilst still 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.
These carbs come with anodized reducing sleeves fitted to the 40mm outlet spigots, taking the spigot outside diameter down to 36mm for direct fitment into your OEM engine rubber boots, the inside of the sleeves are tapered down for port matching. This carb kit is custom built using unique mounting plates, stainless steel throttle and choke shafts, along with new fuel connection spacers so as to best match the OEM Honda 76-80-76 carb centre to centre spacing’s for direct fitment to Honda CB750 K models. They will not adapt to the OEM air box.
IMPORTANT NOTE: There is also the option for a left-hand outside throttle cable connection relocation. If wanting this race bike look option please advise at purchase making a note in the message box next to your name details in the check out..
When installed using our 70mm long POD filters this kit fits neatly in place coming up 10mm or so short of the space taken by the OEM air box.
Before rushing in and ordering please firstly check your carb spacing and carbie sizes for compatibility.
Please confirm the following before ordering and do contact us if you have any concerns, the reason we do request you confirm your measurements is that with these older bikes, engines and or components may have been swapped out in the past and there are a couple of different carb spacings with the earlier and very late SOHC models. A mm or two when using rubber connectors isn’t an issue.
A= 76mm spacing centre to centre between carb 1 & 2)
B= 80mm (carb 2 & 3)
C= 76mm (carb 3 & 4)
