Pro Circuit FCR Mixture Screw (Keihin) - Manufacturer Ref: FMS07250
Replace the hard-to-reach mixture screw under the float bowl with this screw designed to simplify adjustment. Machined from red anodised aluminium, the Pro Circuit screw can be turned by hand — no screwdriver needed — for quick adjustment of the carburettor mixture during bench tuning or riding. It fits on Keihin FCR carburettors with a pump for 4-stroke engines.
Practical for fine adjustments on trails and competition machines, this screw eliminates the need for contortions to reach the screw under the bowl and allows for quick mixture corrections. Common application examples: Honda CRF 150 R (KE03), KTM XC 525 ATV, Yamaha YZ 250 F.
