my rectifier burnt out the other day and left me stranded.
Luckily I wasn't too far away from home and my wife came through with the car. We jump started the bike & I got home without incident.
Anyway, after looking around on the net for some info I can across this site, which swaps the crap Honda r/r for an R1 r/r unit:

Just thought it might interest some

The link 'how to know if your r/r is about to die' is also good & mentions why putting a PC cooling fan over the recifier (which I'd done by the way) is of no use!
Cheers
