Exciter year ?

[Johnny Speed]

Registration card says 87-would like to verify, serial # is : 82M007707 , also
I can not see any spacers on the bottom chaincase sprocket and it floats 1/4" - is this correct?

mine had one washer behind the gear,i added one more to line up the gears,it can still float outward some,

82M is a 1987 http://www.vintagevmax.com/sled_serial_numbers.html

Yes, the bottom gear moves I guess for self alignment ?
