British Bikes / Triumph 3TA mystery!
« on: November 01, 2020, 02:10:12 PM »
I have a Triumph 350cc 3TA engine, 1961, and have found a 1/4 BSF threaded hole in each of the rocker boxes and I cannot fathom out what they are for. The wall thickness is only about 1/8 ins.
Has anyone got an Idea what they may be for?
