Thanks: 1

I Ride:
FCR Instructions:

Lineaweaver Kit Instructions:

Air boot / carburetor inlet bell, float bowl and slide lid
Main fuel jet
Pilot fuel jet (long skinny jet near the main jet)
Pilot air bleed jet (Located under the inlet boot bell, left hand side, viewing carburetor from rear)
With the float bowl removed pull the accelerator pump free from the socket (A firm yank with pliers will suffice)

Place said rod in a safe place just in the event you should ever decide to convert over to Alcohol as a primary fuel. LOL

Install kit:
Install a #150 (supplied) or #160 main fuel jet
(climate dependant)

Install the "Lineaweaver" needle using the as delivered clip position #4 - #6 counting from the top.

Install the kit supplied pilot fuel jet (48 or 49L)

Install the spring and odd looking tapered screw into the pilot air bleed threaded bore. Turn said screw in until firmly seated, then back out 1/2 turn

Reassemble the carburetor with exception of the "plastic" inlet bell

Turn the "Pilot Fuel Screw" (underside of carburetor body between inlet port and Venturi) in until firmly seated then back out 1 1/2 turns

Important Note:
The new "Adjustable Pilot Air Screw" is slightly taller then that of the OEM fixed jet. Take care in removing just enough material from the bell in order to allow proper seating. The bell is plastic and a simple dremel tool and / or equivalent shall make short work of said modification. Try and fit the bell first and you shall clearly see my point!

Fine adjustments will likely be required as many variables do exist.
In short, said kit should put you "very" close to optimum.

OEM Float level is 9MM and should not require adjustment

I am most always available for assistance
Best of luck and thank you for purchasing my product
