One fine autumn Sunday

A little ride in the Scottish Highlands, 20th September 2020. Starting from home, near Pitlochry in Perthshire, up the A9 to Dalwhinnie with a brief stop at Druimuachder for photos. Then the A889 to Laggan and along the A86 to Spean Bridge for a call at The Commando Memorial. The A82 then took me up...

Re: Replacement alternator

Worst idea ever was use a Zener to shunt the power to ground but there were a lot of "worst idea ever" used on English bikes when they were faced with the competition of the 60s. I know what you mean but, when it comes to 'worst', I think that the system used on the T20 (and other small Triumphs) t...

Re: Replacement alternator

OK, you asked for opinions so here you go: It's an expensive solution looking for a problem. The stock BMW system is proven, reliable and repairable. It is more than adequate for the day to day needs of the bike with sufficient extra power for a fair amount of additional current for accessories. ­ W...

The 'alternative' solution is to use an image hosting service. Yes, it's another log in but it does mean you don't have to mess about with image sizes. It also means the image that gets seen doesn't have it's quality degraded by the resizing process and you can also link as many images as you like t...

Re: Considering airhead mono purchase

The R100RT I have is a 1995 model. Compared to the earlier bikes braking and handling are much improved. It is almost a KRT but with boxer engine. On the subject of brakes... According to the lists, the Mono airheads got the same front brakes as some K100 and K75 models from 08/88. Prior to that (b...

Re: Considering airhead mono purchase

There are very few differences in the Mono bikes from '85 to '95. I think condition and mileage are probably the only parameters you need to worry about.

Re: R100rs 1980 70k kilometers Carb balancing

What you say is obviously correct as far as it goes... but... the real point is that an motor where all of the parameters aren't at least close to each other can't be balanced by any method. As I said above, an exact balance between the two engines isn't possible. There will be differences in the ca...

Re: R100rs 1980 70k kilometers Carb balancing

All I'll say is that I've 'done it by ear' on a number of occasions, for various reasons but, when I have checked it with vacuum gauges, it's always required further adjustment. Might be my ears... might be my bikes but I wouldn't be satisfied with a 'by ear' setting except for the short term in an ...

Re: Frame..

There are specialist frame repairers. I've used Maidstone Motoliner in Aylesford, Kent who are very good... but I realise that isn't so easy for you. There must be specialists in Ireland. Ask around, a good bike shop will know where the nearest one is.

Re: R80/7 valve cover

Motobins and Motorworks both offer replica BMW covers at just a little more than the price of these. Motorworks, in particular, may be able to cut you a deal on a second hand pair for an even closer price.

Re: R100rs 1980 70k kilometers Carb balancing

Before you can even hope to balance it, you need to get it running reliably on both cylinders... it's a waste of time otherwise. Get yourself a set of balance gauges. People will tell you carbs can be balanced 'by ear'. Maybe a very experienced mechanic can get an acceptable balance that way but, if...

I have had keys made from Non-Nieman blanks which work. They aren't exactly the right section but they work in a pinch. I tend to keep them as spares so as not to wear the relevant locks.

Re: Airhead keys

The other reason why many High Street key cutters won't cut Nieman blanks is because they are steel. They will wear the cutters quicker than the brass blanks they're designed for. I think you can still order keys by number from BMW at a price... but... the key code also describes the profile of the ...
