Go to the local sporting goods store and buy some of those chemical hand warmers. Then go to the office supply store and buy a bag of rubber bands. Each morning simply open two hand warmers and rubber band them to the grips. Voila! Problem solved.
You can find in some moto-stores (try BMW Dealers, or any Honda shop that sells a buttload of Goldwings) a kit for about the same price, that's similar - but doesn't use that damn resistor for the "low heat". Rather, it uses more than one circuit for each grip heater. It might be $5 more - but you'll spend that in shipping. NOT that I'm sayin' "don't buy from Rider Warehouse" or anything. Just do a bit of lookin' around.
Happy Birthday, Buz! Didja take a celebratory ride yet? (as if I had to ask!)
One of my friends, upon turning 40 decided to "Ride his Age" - that is, made up his mind to attempt to ride 40-different bikes by the time he turned 41. I'm not sure where he's at with it, but he was getting close.
That's a lot of coppin' rides, but he probably was able to knock-out 15 or so from his own revolving stable.
I've had these on my bike for almost 3 years and they've been great.
Personally I wish the "low" setting was just a bit warmer. The "high" setting is perfect for those super-cold days though. The best solution would be a "heat-troller" like Gerbings makes for it's jackets that would give you finely adjustable heat. I haven't seen a kit like that though, and maybe it wouldn't work as well for grips as it does for the jackets.
I find the grips a much more compelling solution, cause you can use them year round without having to wear big bulky winter gloves. If you get caught out in the rain in the summer, etc.. the heated grips can come to the rescue when the winter gloves are left at home. And frankly when I tried on the Gerbing's gloves I wasn't real pleased with the control feel.
And you just can't beat that they're 1/8th-1/10th the price of heated gloves.
