1983 70... Blue

My dad came home one day and rolled this and the '79 110 out of the van. I was 4, my brother was 8 but somehow we didn't destroy it soon after. We probably checked the oil maybe 2 or 3 times in the 18 years it ran, never changed it (we were kids with no tools... gas was cheap though). EVERYTHING on the bike is original... it's just missing a few stickers... even the tires are original. Plastics aren't even cracked. The seat is a bit worn though...from being outside.
I need to rebuild or buy a new pull starter, rebuild the motor, buy a new kill switch, new tires, TRY to find a seat that is OEM Honda and get either a stock exhaust or a Cobra pipe just for the hell of it.
Oh yeah... before I forget... I will NEVER sell it.
