And the K engines [head cams top end and the complete ignition/injection system] end up in the ubiquitous A series mini......converting an ancientpushrod engine to a twin cam fuel injected 16v engine.

All in all a strange kind of pedigree.....

"The first models were not designed to run with unleaded gas. This modification started only in January 85 for K100 with frame number 0007291, November 1984 for the K100 RS (frame number 081107) and frame number 0024999 for the K100RT. "


So does this mean that my restoration project serial number "F0040448" built in July 1984 requires leaded gas?

I have got almost 50k miles on my 84RT since I got it in 2013.

Its never seen leaded petrol or an additive in that time. However it does not like that E85 stuff that France seems to like.

If it ever did become an issue just swap heads with the 92 LT...

But I have been reading on other forums about putting fishing weights and lead shot in the tank. Got me thinking about corrosion inside the tank because we never ever mix lead and aluminium in roof flashings because with added rainwater [admittedly with sulphuric acid in it] you get electrolytic action and corrosion.....

Added on the web page is a rumor going around in the late 70's.
They were pretty close to the truth.

Torque reaction?

Bet they never expected the talk reaction they got and still get.

Didn't BMW spin the alternator in the opposite direction to counteract the torque effect?
My K-100RT doesn't seem to have too much torque reaction. My old R-100GS had a bunch, so does my Moto-Guzzi V-1000.
