Northern Power Sports, a local snow machine/motorcycle/ATV shop where I picked up the screw-in studs, and also picked up a pair of handlebar muffs. These are nylon covered thin foam which slip over the ends of the handlebar grips and controls and are held on with Velcro straps. They are kind of similar to the Hippo Hands that folks rave about but these were about ½ the cost. I think that they are stiff enough to stay open and it's very easy to get your hands in and out as the opening is pretty large. I like that I can still glance down and see the controls. The main concern is whether the wind would push hard enough on them to partially press the clutch or front brake lever while underway. If they do, then I may need to fabricate some sort of support to keep them from touching the levers. They barely fit over the handlebar mounted master cylinder reservoir. Also the bright green Arctic Cat logo doesn't match anything else on the bike.
Revzilla finally has free shipping to Alaska. I ordered a pair of Gerbing G3 heated gloves. Last May, after a very cold ride to Anchorage, I had picked up a heated liner and dual controller. These gloves plug right into wiring built into the liner sleeves and the current can be set with the second knob on the controller. The gloves draw 2.2 amps max and when combined with the 6.9 amps max of the jacket liner, this could become a significant percentage of the 23 amps generated by the stock alternator.
I finally dug into the heated grip wiring after finding a wiring diagram on Snowbum's BMW site and discovered that the two wires from the switch to the grip heating elements had come out of a splice located under the speedometer housing. It was a pain to reach the connector and it looked like the splice was there to simplify removing the handlebars for servicing the bearings. It wasn't a factory style connector but had tiny screws clamping of the stripped ends of the wires. But after a lot of fiddling, the anemic heated grips are now working again though the switch only seems to now have two positions instead of the three. So I'm not sure if I lost low or high and a lighted switch would be a great addition.
I'm still trying to decide if I should drill a large opening in the right lower fairing for the front upper sidecar mount. Some BMW purists within our local Airhead group say that I should leave the lower off rather than deface it with a 1¼" hole. I'm inclined to drill the hole as the airflow would be more controlled and the bike wasn't pristine even when I bought it over five years ago.
