Inlet valve for  Kubota D1403, D1503, D1703, D1803, V1903, V2003, V2203, V2403, F2503. F2803  engines.
 
Manufactured specially to our own specification with a slot machined into the head of the valve to facilitate lapping. Using a screwdriver inserted into the slot makes it easier than using the traditional rubber sucker that we have found no longer adheres to the valve reliably.
