Well, I tried and failed, I tried everything I could think of to get the R1 speedo to work, but no dice, the fan didn't kick in either, even though the temp got up to 92. Everything else worked,
I think I have a duff R1 5JJ cockpit.
I unsoldered everything and put the original Fazer cockpit back on and everything works just fine, the cockpit is foccin ugly though, as far as I know, apart from rewiring the cockpit plug, it should be a straight swap.
Now just need to mount the indicators, tidy the wiring, swap the bars and fit some bar-end mirrors.
Oh BTW, it was just a coincidence the mileage on the two speedos were only a couple of hundred miles apart (18.9K Fazer and 19.1K R1).
Thanks for your help,
