Direct replacement for the stock spring and exactly like the old Merge Racing spring. Gives a much more consistent accelerator pump squirt. Eliminates the need for the 'O-ring mod', wire or zip-ties on the pump arm. Fits all Keihin FCR-MX carbs except '07-'08 CRF250/450.
Not for the stock DR650 carburetor Fits FCR-MX conversion Only
