G'day folks. Is there anybody out there with a bevel Ducati that has Veglia instruments? (My MHR has ND clocks)

I need to make up a tacho cable inner to replace a busted one on a mate's 1978 Duc 900 SS.

I have a long piece of new cable inner that I can cut to length, and I have the forming die to press the square ends onto it, but I don't have an intact inner to measure the length. I can have a guess at how much the ends should stick out of the outer, but would prefer to get it right. I've already stuffed up once by making one that's too short. I cleverly put the pieces of broken inner together to measure the length. But unbeknownst to me there was a piece missing.  ::)

The total length is not important. I already have the cable outer. What I need to know how much longer the inner is than the outer, or (in other words) the length that should be protruding at each end.

If anyone has an intact cable lying around, could you measure it for me?

Thanks,
Cam

 
Hello Cam

How about you make it 50mm longer than you think it should be? Fit it then figure out how much too long it is. Then you will have the answer...
 
Yes. Thanks Jod. That's one option I'd already thought of.  ::)

I reckon I'll just have to go to his place and check the length needed to give plenty of engagement each end. It's about 45 mins each way, but a pleasant ride.

Cam when the inner is sent up all the way into the tacho it is about 6mm shorter than the outer at the drive end.

Jason at Manly Auto Instruments would be your best bet...
