hey gang

Any of the brain trust have any suggestions to crimp the ring on the ND speedo/tachs without destroying the ring and scratching the freshly powder coated instrument cup  :-\ . 

the local speedo shop say they don't do japanese stuff .... yikes!

It's a while ago since I faced this dilemma but, I got hold of some attractive and in keeping clamping rings which are removable if required. This means if I scratch a covering shroud or need to get into a clock then I can.

Quite fortuitous in the event as my tacho has stopped working...and then the tacho on my old Beemer packed up in sympathy..Do these bikes talk to eachother !

Hi
I had the same issue got my surrounds repainted and new glass then head scratching until I was put on to Gavin Spencer, he did a perfect job using the old rings. The clocks look great and the rings look like new, he also fixed the damping and made sure they worked correctly all in all top bloke and not too expensive.
Good luck Coventrykid
 
If you aren't adverse to paying someone else to do it  - send them to www.cb750faces.com

If you want to do it yourself, then I suspect that the correct way to do it is to form the locking ring closed with a forming die.  You need a lathe and some way to carefully hold the instrument by the freshly coated bezel/cup, then you could create a tool that would gently form the ring into closed position as you turned the instrument very slowly.
 
thx guys - i ended up sending them to wolfgang as he's at least on the same continent - but having done it once for my 1200 instruments i am thinking the weathered gauges on the SF2 now look  awful sweet and don't think i'd bother refreshing these ones
