I need to recalibrate my speedo as it reads 70mph when others show more like 60mph. I took it off and see there is already a hole drilled to access the adjustment screw. How many turns should it require and would that be c/w or anti c/w when viewed from the back? thanks.
Speedo calibration advice needed

Take the speedo off the bike and mount it on a stand of some sort which gives you access to viewing the dial face and adjustment screw. With a short length of speedo cable inner with the squared end in the speedo and the other in a variable reversible speed drill. Operate the drill in the right direction and increase revs until you see 70mph on the dial, move the adjustment screw until you see 60 mph with the drill at the same revs.
