What This Tool Does

Valve clearance adjustment on air-cooled Triumph twins requires precise socket engagement and stable pin guidance to prevent fastener damage and ensure repeatable measurements. This kit provides both: the L-shaped wrench delivers leverage without fouling nearby components, while the guide pin prevents cam-out and keeps the feeler gauge parallel during the critical adjustment sequence.
