Hey DMF, I got the gauge in the mail yesterday and will install and get a warmed up idle temp today. I'm curious if I can use my air temp sensor from my other bike to measure ambient air temp. I'll have to look into that. I will be sure to include ambient air temps and humidity (definitely a factor in Florida) with my readings.
Your relocated voltage regulator is actually in the stock location for a Vee! I never understood why so many bike models have the voltage regulator located so close to the engine.
As for your heated grip concerns, I share them. On my other bike, a 2006 Triumph Daytona 675 I had installed a set of heated grip elements and I believe it was the cause of my stator failure on that bike. I had a FH012 regulator on that bike as well. The stator output on thar bike is 400W (I think your K7 is the same, or maybe more since you have the SV stator). I had changed the engine on that bike at 36k miles and while the stator was functional, it did have a blackened wire or two when I pulled the engine. The replacement engine had 8k miles on it when installed (based solely on the word of the seller) and went out 10k miles later. I liked my heated grips when used on conjunction with some decent gloves, but I won't do it again on a bike without a high output stator.
