This part being universal, it may require adaptations
Replace the small part that makes all the difference in the throttle behavior: the 115 g lever spring Mikuni is a spare part designed for SBN34-46 carburetors. Manufacturer reference 730-03027, this return spring fits between the lever and the throttle control to ensure a precise and consistent return of the throttle during opening and closing phases.
Ideal for riders and mechanics who are rebuilding a carb or want to replace a worn spring, this component allows you to regain the original play and feel of the throttle lever. Its installation occurs during the reassembly of the carburetor body and integrates directly into the throttle control system without modification.
Always prioritize a visual inspection and adjustment after installation to ensure smooth operation at idle and during acceleration. An OEM Mikuni part, it is aimed at users looking for a restoration faithful to the manufacturer's specifications.
