(85-02) VMX1200 V-Max Vmax VMX12
(84-93) FJ1100, FJ1200
I would double check the clearance. You typically have larger gaps Vs a smaller gap. If the valves and seats where ground then the machine shop should have ground the end of the stem to match the material removed during the valve grinding process.
The other option is to remove the valve(s) and dress each valve stem to get the correct clearance. But if its more then a couple, you will be spending lots of hours recording clearances and verifying the valves over all length.
