Okay, the bike had other ideas and went for the NEVER ON option. Did 300 miles today, mostly at 90-95 so fan not a problem. Then got into Bangkok at the hottest part of the day...
Temp guage did a bit of yoga but did not go too mad. Only have to get the bike across town, on Saturday, then she is in storage till August.
Daps, if you do find the t-stat, that would be great.
