3/32 hole drilled in a bit of soft rod/stick will give you a workable reset until something better comes aroundWhite 500C heads retorqued - and still moving. I'll do them again in about 100 kms. Camchain and valve clearances readjusted at the same time.

Speedo working, though this one has a damaged trip meter and missing reset. I'll probably just install a grommet to fill the reset hole. Tacho working.
