Another occasion

This is as good as life gets.



The two costliest repairs I have suffered on my 1975 BMW R90/6 ‘airhead’ have been replacement of stripped nylon gears in the totally mechanical instruments – the drive is by gear and cables. Some genius in Munich decided a nylon gear beats the 2 cents costlier brass alternative used through 1969, and both stripped. He was probably British, and formerly worked on Triumphs. The tach gave out at 60,676 and the speedo joined it in sympathy at 61,724. If the needle goes crazy, the gear is stripped. If it just jerks about then a new cable is called for, the Teflon liner being worn out. The last thing you want in that cable is lubricant, which will only hasten its demise.

The work was done by Palo Alto Speedometer – unreservedly recommended. I used to use them on my old MB’s instruments also – but at $300 a pop they are not cheap.

A properly tuned air cooled BMW boxer twin is happiest at 4,000-5,000 rpm. Many owners ride these at far lower revs, constraining proper oiling and doing awful things to the crankshaft. It does well to remember that Germans only understand one thing – a strong hand at the tiller. Subtlety has no part in their make up. And, by the way, not only is the tach needle as stable as can be, given the early Industrial Revolution technology, the speedometer is also dead accurate.
