I think it's 4mm.Removed tank and panels from the GT ready for painting and off to the sprayer- going back to original factory silver blue for the first time in 35 years! Had to remove the Bakelite knee pads , that was fun.
does anyone happen to know the correct thread size for the tank badges?
When I was at Stanco, there was specs from the factory for 3C that had as you say 0.25 to 0.35 for valve clearance that did not mention inlet or exhaust. At that time it also seemed that the cams moved so much in the cam blocks that we used those figures for the greatest clearance at any point of the base circle, not at TDC by any markings, as the clearance was inconsistent even a few degrees either side of a "TDC".Thought I should measure valve clearances before a proper ride. Geez. 0.46 on intake #3. Why am I not surprised?
Upon reading period owner manual, I set about adjusting to 0.25 to 0.35, observing the drawing of an 0.35 feeler guage inserted.
I'm reading here that 0.20 to 0.25 is correct. Did Laverda engineers back in the day suggest sloppy clearances?
Forgive me if I've missed possible previous thread on this subject.
