Thanks to all.

And still get the clutch to free off enough.

Anyone have any ideas on how to fix this problem?
Thanks.

Have you checked for in-out movement of the basket, or up-down play in the shaft.
Chains that are overtight is another remote possibility. ?

British Bikes / Bonneville's Got a Crunch
« Last post by ramwing7 on October 05, 2025, 09:41:37 PM »I have a 1973 Triumph Bonneville T140V that is making a crunch like noise when the clutch lever is pulled in. It does it toward the end of the lever movement.
I've replaced the clutch lever, the clutch cable and all the clutch plates. I filed the slots in the clutch basket to remove rough spots and the plates seem to slide evenly.
I've now disassembled the clutch basket again, but I think I can still feel a rough spot when I push in on the end of the actuating rod. Not much, but I'm thinking that maybe the noise is being amplified by the assembled clutch plates, springs, etc.
Looking for ides as what's left that might be causing this noise.
Many thanks.
Ron
