Triple camchain covers

Sat nav has told a lot of us how fast we are actually going, so far everything that I have driven and had a sat nav on has overread by a bit, the ecpetions are the last two Mercedes e class estates and they are both bang on

I believe it's mandatory that speedos don't under-read. Hence they err on the side of over-reading.

Well, Laverda thought an RGS needed rubber mounting but I'm happy if I can replace it to stop the wobble.

Anyone have the dimensions handy or even make one for me? I'm not an engineer (or mechanic) and would pay for one.
 
Andy,

The RGS fairing mounts work fine... as long as they are in as-new condition!  As soon as a bit of wear and tear, or rot, sets in, the whole caboodle starts wobbling around, will all the associated consequences!

Guess the factory went bust before they were confronted with too many warranty claims concerning fucked instruments, etc.  They would have needed to revise the mounts eventually.

RGS was introduced 1982, factory more-or-less down the drain 1986.  By then, they were only just issuing frame repair kits for the early SFC1000 when the first snapped RGS frames started appearing.  Reckon the first instruments would have died around the same time.

My Laverda speedo over reads by about 12%. I can cruise on the highway (speed limit 110) at 125 on the speedo without risk of upsetting Mr Plod.

Never tried to calibrate my tacho, but I suspect it's no more accurate than the speedo. I suppose I could do the arithmetic with gear ratios, rolling diameter of the tyres, etc. to work out a conversion from GPS speed to theoretical engine revs, then see if that agrees with the tacho - but I can't be bothered. It doesn't matter much anyway. I know when to change gears.

The speedo in my Mitsubishi Delica under-reads. If the speedo says I'm doing 100kph, the GPS will be reading about 105kph. It would be a bit of a trap if I wasn't aware of it. Never seen an under-reading speedo on anything else, except for ones that always read zero.

 
I have fitted one of those little pushbike computer thingies; acts as a clock, speedo, tripmeter, average speed indicator, maximum speed attained (must reset if pulled over by Mr Plod). It shows about 10 km lower than the speedo but as the sensor is mounted on the rear wheel, tyre wear changes to speed indication somewhat. Handy bit of kit, specially when your speedo drive stuffs up in the middle of Whoopwhoop  >:(.
