Good end to what could have been a bad situation. As it turned out the Bowden tube had a rough end piece which wore through and frayed the cable strands which caused the stretching until they just broke. JPS sent me a new clutch cable and bowden tube. At no charge i might add.
The new tube end pieces are constructed out of a plastic fiber material rather than metal which was used on the original which caused the problem.
all installed worked perfectly.
