Gent's,
Mike GTX has had an Illuminated Fan Switch on his Gen 1 for years .. he also fitted one to my last Gen 1
.
The idea is that you start the fan 'well early' when entering Spanish Villages and Towns .. these can often be chocker block, stand still slow on summer time (40c in the shade) week-end market days, etc.
The early air flow helps keep the engine closer to optimum working temperature .. not struggling to cool down .. it works OK down here so I recon it should up there in Gibson County
.
As for the heat on your legs problem .. it can be a serious distraction. Try a section of 'heat shield' type plastic inside your trouser legs. I'm thinking stuff like cut up 'cool bags' used for frozen food shopping, maybe.
Down here in Spain the constant stream of sweat running from you lid, down and out of ya boots, helps to keep things cool .. Not! Oh how we suffer
By the way .. that Silver Foil Cool Bag type plastic stuff idea works in reverse in wintertime .. helps to keep your knees warm ;o) Old Long Haul Riders tricks
I'm booked in to be drifting around up North myself .. out on the Outer Hebrides Island of South Harris in June .. long way home via the Highland Mountains and over via Berwick.
