| 1975 commando 850 mk 3. Can't shift into 4th gear.
No warning.-just happened out of nowhere.all other gears and shifting are o.k. except for some noise at higher rpm in 3rd.Does anyone have idea of what may be wrong? Clutch was slipping some before this happened.
I checked clutch cable, and clutch engagement. Seem to be ok.
Is it something one can diagnose without getting into inner gear box
