Keep the tank full as possible. That way no condensation can develop in it. Only 6 weeks, doubt you will need to put oil in the cylinder. Trickle charger - good idea. Fuel stabilizer, add it before you fill the tank, drive it home so the stabil gets into the carbs. You can also shut off the fuel and let it die to empty the carb too. Doubt flat spots would be a concern in that short a time especially since it will be in a garage on concrete. If you have cats that roam around in your garage area, cover the top of the bike with towels - they like to sleep on bikes lol. A good wash and a very good waxing is also a good idea right before putting it in.
