then would be 1979 1340
Yea but you gave it to me ,offerd in late 78 as option you could still get the 1200 till 80, you threw me with the 66-71 tank emblem was hard to see if it was a generator or altenater but looked like not generated as far as the pic goes witch put me the intraduction year of altenator of 1970 with the emblems and in 72 the tank emblem changed that why my guess was 70-71 , Yes real nice scoot and it looks sweet I had a last 80cu. shovel FL and yea it was sweet rode that bike for many yrs.
there should be a vin number on the frame or the engine that will tell you the year . if you can find it and post it I can help you narrow it down...critter
