my spree has been sitting awile so it probably would be a good idea to change the tranny oil.where is the drain/fill plug located and what kind of oil should i use?
Pull the drain plug on the left side. Tip the bike on it's left side and drain. Refill with 10w40 (I use two stroke oil) and refill. Allow the excess to drain before reinstalling the drain plug.
If the oil is really nasty, you'll want to flush and fill this several times. Might want to wait until you're low/out of gas, you have to tip the scooter nearly horizontal to get it all out.
