my bike is an 2010 sportster model 48 xl 1200, i let it sit too long when i was gone, and got back home and though it was two quarts low on oil, and i have not startd it, yet, but now im thinkin it just needd too be start,d before i check it. bc it sat,, so now im too full on oil. and can not find the oil drian plug too let the oil out and put new oil in.. so if u can hel me find the oil plug, i can finger out the rest too get it to the leavel i need to be at,, im thinkin there is 5 quats in it right now. so i need to take two out, but cant find the plug,, is it the hose with an clamp on it. or is it a blot on the chutch cover.. or is it on the frame somewhere. plz help
