Description
Dialing in valve clearance on a four-stroke top end comes down to finding the right shim thickness, and this Wiseco refill kit supplies five 10.0 x 2.35mm shims for that exact step.
Valve clearance changes as the valve, seat, and retainer wear in over time, and the standard way to correct it is swapping in a shim of a different thickness rather than adjusting the valve itself. Keeping a range of shim thicknesses on hand during a valve adjustment or head rebuild means the clearance can be brought back into spec without delay. Wiseco builds this shim into its broader valvetrain lineup alongside its titanium valves, Garage Buddy steel valve kits, and cam chains, all aimed at getting a four-stroke head rebuild done right.
- Five shims per kit, each 10.0mm in diameter and 2.35mm thick
- Sized to fit valvetrain applications using the 10.0mm shim diameter
- Lets a valve clearance check finish in one session instead of waiting on a single special-order piece
- Part of Wiseco’s four-stroke valvetrain lineup alongside titanium valves and Garage Buddy valve kits
- A practical companion to a full valve adjustment or head rebuild
- Useful for keeping a stock of common thicknesses on hand for routine maintenance
For any 10.0mm shim application needing the 2.35mm thickness, this Wiseco refill kit puts five of them in hand for a clean, in-spec valve clearance adjustment.
