Pulled the instrument panel apart tonight, several bulbs blown so will try some LED bulbs and report back.

BUT what is the light immediately to the left of the indicators bulb? The wiring diagram is hard to read but it seems to say something about High beam, but so is the one all the way to the right!! Any ideas?

BTW it's the first vehicle I've ever seen that doesn't have a charging light!! Might add an elcheapo voltmeter.

Also pulled the tacho apart and yep the balance weights all fell out. I'll take it to Otto Instruments to see what they say. Should be easy to fix.
 
There's one light that tells you if the lights are on (well, they are a bit dim) and the other is high beam.
 
Hhhmmm, OK, have found some leds that should fit the instruments. Getting a swag of them from China, will see how they work.

More of a surprise to me was no oil pressure light  :o

well - no wonder, cause the Laverda HAS no oil pressure. The whole oil system does not have any jets - how should it build up pressure and - what for?

The oil-pump is designed to produce high throughput. The oil - more or less - just flushes the engine parts. The only exception are the crank bearings, but they are feed by the centrifugal forces the slingers produce, not by the oil-pump. Hence no oil-pressure warning light, as it would be always on...  ;)
 
Reminds me of my 750SF. I rode to Vancouver a couple of years ago and needed an oil change when I got there. The local government frowns upon dumping used oil in the back lanes so I went to a near by motorcycle dealer to get the oil changed. Half a mile later my "oil" light came on. Limped back to the m/c shop and we checked things over; removed the tappet covers, yes there was plenty of oil coming through. I assumed there was a wiring problem somewhere and went back to where I was staying and checked the wiring diagram. Well that's weird: the wire from the "oil" light goes to the regulator! Well you can guess the rest. On the Nippon Denso clocks, the warning lamp labeled "oil" was actually the "gen" lamp. Now I know a bit more about Laverdas.

So the LEDs I ordered finally turned up yesterday so I had a play with them (the LEDs...).

There's 2 types of carriers for the T5 bulbs in the RGS dash, the 2 push in carriers at the top for the back lighting, and the twist in carriers for the other lights.

The two backlight ones I fitted with these http://www.dealextreme.com/p/t5w2x4-6d-0-2w-7k-18-lumen-3x3020-smd-led-car-white-light-bulbs-5-pack-dc12-17v-48717

and they worked really well. About twice as bright and clearer than the bulbs, so I was happy with that.

Then I tried them and also the single ones like this http://www.dealextreme.com/p/dc-12v-vehicle-white-led-bulb-lamp-9090 but they seemed to interfere with the connections somehow and it blew the fuse for the lighting circuit, With the single one, it also seemed to be burning up so I quickly shut down and went back to the bulbs.

So with the twist in carriers there seemed to be some sort of interference with the LED circuitry. When I go into the office next week I'll check them out under a maglight so I can actually see what was going on. But for the backlight ones it worked like a treat!

I suspect these ones will be brighter again so I have ordered some of these as well, will try them when they turn up and report back http://www.dealextreme.com/p/0-1w-t5-2-1210-vehicle-decoration-signal-white-lamp-bulbs-dc-12v-2-pack-34609

 
I'm expecting you're right Cam, but having 52 year old eyes and my glasses don't really help I need to look at them under a decent magnifying glass  :)

Will report back. BTW the triple ones didn't seem to care which way around they are so I suspect they have diodes in them to make them bipolar (schizophrenic?).
