\"Clocking\" speedos
 

Has anyone clocked a Ducati speedo? Forwards, I mean, of course.:P

My cracked speedo glass hads got alarmingly worse today, to the extent that I reckon it could fall out altogether, or at any rate let water in.
It seems to be generally agreed that the glass cannot be replaced.

2nd speedos are easily available (anyone here got one they'd be prepared to part with, BTW?) but I'd like to maintain my current mileometer reading.

Power drill and some patience?

Well yes, but I wondered if anyone had actually done it. I don't want to buy a 2nd hand clock and then wreck it.

i think you will find that drill will only run at about 70mph?

depends how much calibration needed but you could get through a few drills?:o

possible solution is buy second hand speedo slightly over what your correct mileage is, buy a third speedo and run that until the bike has reached the total miles on the replacement speedo

i.e damaged speedo (a) says 5k
replacement speedo (b) says 6k

use a third speedo(c) for a 1k unitil A=B then sell on speedo C

speedo (c) could be in kilos and convert them, kilo speedos are very cheap, coz no one really wants them

never done it on a 748, but I have taken a few car speedo's to pieces. Generally there will be a gear drive from the end of the cable drive and the tumblers that show the mileage.

Remove one of the grears ot tkae it out of mesh, then it's a simple case of rotating the tumblers to give the correct mileage. Replace the gears and re-build the speedo.

Alternative would be to buy a new speedo and keep the old one to show the mileage at the clock swap.

The problem with the Ducati speedos is that you have to physicaly cut the casing to get them open. People manage it though, just look at the ones with fancy dials in them.

Good point! I hadn't thought of that! You see Italian flags and such-like.

Thinking about it, I'm sure Bungi's right about the drill. I'd ber there for a fortnight or summat! :)

Few years ago went into my neighbours garage one night and he was clocking another neigbours speedo.

I said 'winding it back Andy?'

Andy said, 'no winding it forward'

Me:puzzled::puzzled:

Andy replies, 'its a company car and if i don't do enough miles i've got to keep it for another year, so i'm advancing the mileage:lol:'
