He was thoughtless, because he assumed that I was having a go at BMW's methods. I have been a BMW GS owner until 18 months ago, (with a modified indicator set-up that "experts" on this very site said couldn't be done), and around this site for quite a long time to know that some people speak/type first without thinking about what they are replying to.
Perhaps, instead of immediately criticising, jumping to conclusions or merely being defensive about BMW, whoever replies could ask "why?" or "what problems or issues are you experiencing?". This would be a lot more constructive and helpful than questioning ones ability to ride a motorcycle!
FWIW, I had a 3 position switch wired into the indicator circuit and running a second flasher unit to create a second, parallel circuit on my old R1150GS. I asked the question because I would like a 1200, but with their canbus wiring, I'm not sure it would be so easy or indeed if it would work, hence my question based on BMW's move to standardisation on the 1300 and 800 bikes.
, you must have misread, it's only one thumb that's missing
