Comprehensive seal kits for Keihin FCRs are now available. These include mid-body seals which cannot be sourced anywhere else. We also have Viton throttle shaft seals and stainless steel throttle butterfly screws available for the Mikuni carburettors that are fitted to many of the Yamaha and Suzuki motorcycles. These are replacements for the Yamaha original part 256-14997-00 and Suzuki part number 13651-51010. They are included as part of our comprehensive carburettor kits.
