I have a 2002 model and as I'm sure you all know, these are not fitted with a temp gauge, just a small light. I've never seen this come on (I would assume it would when turning on ignition, as a test?) so don't even know if it works. Took the bike out yesterday for a couple of hours (nice warm day) and noticed after riding that the fan wasn't on (something I will investigate very soon).
This got me wondering and wishing the bike was actually fitted with a gauge, rather than a stupid light, so wondering if anyone could recommend one that will be suitable for these bikes?
