I use Klotz Flex Drive in my transmission, it is designed for 2-stroke powered racing transmissions. Clean carbs, bleed brakes, clean and lube chain, mix your fuel at 32:1 for the first tank, change plugs (i use B8EGV no resistor, there are no TV's or radios in the woods! LOL) clean or replace airfilter, change coolant, put an in line fuel filter on it, there might be some junk in the tank. Last but not least check tire pressure... You live in MI are you going to Bundy Hill, or The Mounds?
