More Motometer instrumentation...information on the BMW R65, R65LS and R45 motorcycles....

Well I'm on a role here...I've scanned in all my Motometer stuff and will feature information on BMW motorcycles that used Motometer instruments from 1973 to, well into the 1990's, perhaps later. I was out of it by then....
This blog features the boxer engined R65, R45 and R65LS models. As well some of the R80's appear to have used these as well.
Left click on the images to enlarge.....
I made pencil notes on the gearing over the years and have scanned this in as well...a bit scratchy, but the effort needed to type it up is more than I'm prepared to do.....

The BMW R65 LS model....the engine and instrumentation were the same for the other variants....gearing excepted etc...

The R65 used a 200kph or 120mph speedometer scale with a cable driven instrument and the tachometer was electronic. 
The R45 used a 180kph speedometer.
Information on how to connect a tester to the tacho follows in some of my pencil notes...

Exploded parts view of the tachometer...

Details to the bottom right of the electronic tachometer connection and odometer gearing details for the 120mph speedometer to the mid RHS.

Exploded parts view of the speedometer...

DQs scratchy notes on odometer gearing...covering the R45 and R65 on the RHS.

Trip odometer details....
Details for the additional Motometer quartz clock and voltmeter offered as an extra on these models are in the previous blog......

Detail of the speedcup shaft bottom pivot length. This wears on the end stone in the bush at the top of the mainshaft and the inside of the aluminium speedcup "poles" on the magnet, eventually destroying it.
You can lightly stone the worn end of the shaft and then tap it though the brass piece in the speedcup to the correct setting...0.140" protruding.
