Broke the clutch cable at the upper lever while on an extended ride far away from home. A friend had a great idea I'd like to pass on. We pulled out the cable from the sleeve, and inserted it backwards so the lead coupling could be used in the upper lever. The sheared end of the cable was now at the bottom by the lower lever attached to the clutch disengage shaft. We used a small bolt and nut with 3 washers and pinched the cable between the washers, with the bolt going through the part of the lower lever where the swedged cable normally attaches. 1 or the 3 washers was slid between the upper and lower tabs of the lower lever, so it would not smash the tab when tightened.
Worked great for the 3 days I was there.
