I'd been tinkering with the idea to fit this next to the 2" tach on the handlebars
courtesy of
www.holden.co.ukIt comes in three styles and costs some 90 Pounds Sterling (150$) plus s/h, but that is not the real issue...
(the thing is all mechanical, old style)
and can be adapted to read oil temperature instead of water temperature (unless you drink tea...)
...where on earth should I plug for the capillary oil feed to the oil pressure gauge,
and where should I drill (drill???
) the sump for the oil temp sender?
???
