I've heard that you can get a "heated grip kit" for snowmobiles at any major auto retailer (in Canada, check out Canadian Tire). The snowmobile kits cost MUCH less that motorcycle kits. The kit consists of: wiring, son/off switch (or temp. control) and two strips that you rap around you handlebar ends. You remove your existing grips, rap on the headed strips, then slide you grips back overtop. This is a popular retro fit with the Ironbutt crowd.
