Yamaha RD Shift Shaft Upgrade Kit - Includes: (This is the Original UK made kit, not the Chinese copy) - New CNC 6082 Billet Housing / PB1 Bronze Bushing - O-ring Seal Nitrile - Shift Shaft Seal - Acetal Shaft Sleeve - Easy to install, no mods required Though they have great transmissions, Yamaha 2 stroke twins aren't known as the best shifting bikes, and as they age shifting becomes even worse. The engine case opening for the shift shaft wears away causing the seal to fail, resulting in a constant oil leak, sloppy shifting, difficulty finding neutral, and missed shifts. Replacing the seal is just a temporary fix until it quickly fails again. This kit helps eliminate those issues. Economy Cycle tested for fitment/performance, highly recommended. You'll notice a difference in shfiting right away as the shaft/lever have much stronger support from the new bushing. The kit helps reduce miss shifts and revving to the moon, as well as making it a bit easier to find neutral. So sure, the kit eliminates the annoying oil leak with double sealing (by the O-ring and shaft seal), but to us as RD performance enthusiasts, this is a performance improvement allowing for precise and quick shifting. Great for street or race applications. Easy to install.
