This tool is used to aide in accurately measuring the closer shims on any 4 valve Ducati [7mm valves]. Set it inside the shim and measure the entire stack, then subtract the tool thickness to get the thickness of your shim. If you don;t have a micrometer and do have a set of vernier calipers then you must have this tool for the job.
2 tools are shown so you can see the tool, only 1 tool is required for the job and is included by ordering "1".
Buy this.

An amazing tool for measuring valve shims. Most accurate I've used and for the price it is a great deal.
