A 'crunch' doesn't sound at all normal, or like any of the common ailments !

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.

Dunno, but I fitted an entire late 60's Bonnie top and bottom ends into T110 crankcases.

Will a pre unit 650 barrel fit on a unit crankcase?

British Bikes / Help identifying a petrol tank
« Last post by gettingold on September 25, 2025, 11:09:14 PM »
Hello, I have been unable to identify a fuel tank that came with a BSA A10 basket case project. I can find tanks with the emblems but with no tank mounted speedometer or I can find plenty of tanks with the speedometer opening but not with these particular emblems. Any help would be appreciated

There's another survivor, powered by a 5hp JAP v twin, and with a Jardine gearbox. It's a nice original bike. This is the only one with Mr Whiting's own V4 engine, and his own 2-speed gearbox.

Hmmm, thats a fairly exotic beast !
And it does have a few suspension points that would require greasing.

Is there only the one and only ?

Whiting V4 - just had it's first run around the block. Although I did ride it 25-odd years ago!

This headlamp is 5 1/2 ", and the switch hole is 1 3/4 "
Anyone know what (Miller ? ) switch this is likely to require. ?

Dunno Leon, tell us ....
