Hi all,

I am after the dimensions of the exhaust valve for the Hercules JXD engine.

I have been offered a set of exhaust valves for the rebuild of my engine. I’ve been told they are for the Hercules JXD but I wanted to check the dimensions of them before I committed.

I have the new intake exhaust valves here but still need the exhaust valves, thus my search.

My engine is at the reconditioning shop and I cannot easily access them at present.

Does any one have any used or new ones on the shelf that they could check the dimensions for me please?
