Can somebody explain to me how I can figure out the year of my Maico? I know it's either a 1978 or 1979 250. I bought it new, had it stolen 10 years ago when it was completely mint, and spotted it on the road for sale a few months ago and the sheriff got it back for me. Problem is, it's somewhat trashed, and I want to restore it to its original beauty. So, to get the correct plastic, I need to correct year Thanks!
