Daily Bird has a strange issue.
Sometimes when I pull into my garage and switch off the analogue gauge instantly pings up so the needle is sitting against the stop pin (almost 12 o clock)
The needle stays there until I have allowed the motor to cool. Then switch on the ignition and the needle drops to it's cold position (or nearly cold if I don't wait too long). If I leave the bike for days without switching on the ignition the needle will stay against the stop.
This problem only seems to happen if the fan has been running (or is about to) as I pull into my garage i.e. the motor is at the hot end of the scale.
This has been happening for some time (couple of years since I first noticed it!) and my initial thought was that it was due to the corroded (and bridged) PCB on the back of the clocks. I eventually managed to find a good PCB but the issue stays with the bike. I've checked and cleaned the temp sensor switch/connections and checked the fan connections and found nothing wrong. Loom earth bundle all fine.
As a side note recent rides have highlighted another cooling issue that may/may not be related. We all know the Bird will run hot if there isn't air passing through the radiator. What I have noticed is that my temp gauge climbs much faster than it ever has. This is to the extent that it moves from just above cold to max (fan on) in less than 2 minutes if I have been riding and have to stop at traffic lights. Rad clear, coolant just changed (no air lock), thermostat is now 6 years old (seems only yesterday when I changed it) the original was 14 years old and still functioning fine, this one has seen much less life than the preivous one which covered 50k more miles! Rad cap is a Honda car one changed less than 2 years ago.
Again any ideas?
