Given the sad record on these clutch cables, you TR owners may want to try something that's de rigeur among us KLRistas: threading a backup clutch cable through the bike right alongside the one that's in service. When the one snaps, it's a 20-minute job to swap in the backup, assuming you've got the spanners required. I'm thinking about doing this for Merkin Muffley; though I've had no issues with my cable, other Jialing owners have.
