I'm not sure exactly where to post this since this is my first forum-post, but I bought a GL1100 1983 but do not know how to tell what version it is, whether Standard, Interstate, or Aspencade. The original owner is not available for contact but I noticed a part-number for OEM equipment, MB9-780. How can I tell what version it is? I've noticed that the gear-shift (I do not know that much about motorcycles, so please bare) will sometimes not change any gears or click even. I have to reach down and pull at it several times and it'll go from Neutral (Neutral light does NOT show when this problem is happening) to second gear, to which then the problem is solved. So...Yeah.
