Gio 250cc doesn't like first gear
 

Hey, My

My Gio 250cc won't stay in first or reverse gear. I just did a winter carb tune and I have the idle set higher than it used to be, could that be the problem?

Also, I'm riding at temps below -20C now, I want to get some small pad heaters for the diff, engine and battery. My plan is to have an AC pad on the engine and small DC pads on the diff and battery. DC directly to the battery, AC to a trickle charger then the wall. I want to get the most from the battery and have the diff heated so the bike doesn't have to work so hard. Any one know where I can get the pads? I'm in Canada and though I can find wholesalers I can't find a retailer. Anyone know where to source 25W AC and DC pad heaters?
