On a recent ride the exhaust valve cap/cover/plug fell off the engine - going well until it happened.
After a long downhill stretch, once the engine picked-up for the next climb it had gone onto one cylinder................
Checked the road and couldn't find it.
LDMCC pre-war spares don't currently have one.
Could anyone advise where I might get one, please?
The threaded part appears to be 1 3/8 OD and 18tpi (35mm OD, 1.5mm pitch)
