Re: R100 Rewiring

EME have a solid state R/R including all wiring for around the same price as the wiring for the OE set up. They also have a kit which you can fit to bypass the warning light if you stick with the stock system. Gamatronics have a neat, low cost , warning lamp which can be set to show either charging ...

Re: Newbie question on parts availability

Airheads never really had " Electronic " ignition. They retained the mechanical advance unit below a hall sensor trigger, and the black box was the same one used on some locally built six cylinder family saloon, so little more than a amplifier for the signal from the hall effect sensor. Th...

Re: Newbie question on parts availability

Both these guys have the factory parts lists on their sites, which will show you what is available from BMW dealers. Most consider that BMWs development of the bikes went the right way and latter bikes are better in most dynamic respects. Mechanically the motors didnt change much, but the transmissi...

Re: Tone

https://www.ebay.com.au/itm/MUFFLER-UNIVERSAL-DUNSTALL-TYPE-DECIBEL-EXH0023-/3609302 I have one of these on my 2 in 1 1000cc R75/7 and it sounds good. Has enough flow to cope, I tried on standard Staintune and it didnt. Fitted right on using the stock bracket and cleared the brake pedal without a de...
