Description
THIS KIT INCLUDES: ONE SET OF MIKUNI RS34 CARBS, A THROTTLE AND PUSH/PULL CABLE KIT, PLUS the choice of either no filters for fitment of your own POD’s, 4 x POD FILTERS included or 16mm silver anodised air-box extenders for using the OEM air-box.
These Mikuni RS34-D21-K RS carbs will breath a whole new lease of life into your Yamaha 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 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 Yamaha FJ models where you can use the OEM Yamaha rubber engine mounting flanges but do need to confirm a satisfactory size match where these RS34 carbs have a 40mm outside spigot diameter. This Mikuni RS34 Kit includes the bank of 4 Mikuni RS carbs re-spaced to the 77-85-77 Yamaha centre to centre port spacing, jetted and ready to ride with usually no tuning at all required, a new push/pull cable set and throttle, and a choice of either 4 cloth/paper dry type automotive pod filters or our silver anodized air-box adapter sleeves.
Pilot Jet: VM28/486-17.5, Needle: 9DZH1, Needle Jet: P-4 (568 Series), Main Jet: N100.604-115
We also have quick action throttle and cable assemblies available, plus Velocity stacks which have no form of filter in them (15, 30,50 and 75mm long) for racing.
Petcock clearance issue: On some models the OEM petcock may interfere with the top of the number one carb where changing to an alternate petcock type bought elsewhere may be required.
IF NOT WANTING TO PURCHASE THE KIT IN ITS ADVERTISED FORM PLEASE FOLLOW THE DIRECTIONS BELOW.
