I think this is more a case of too many dead brain cells on my part. :small3d029: It's no fun getting old. :cry After I did a little web surfing I saw a lot of 900 references for the ironhead 883.

All the historical references I found agreed on 1972 to 1985 as the model years that the Ironhead 1000 were built. I can't explain the owners manual that stated 1970 unless it is a misprint. I suppose it doesn't matter as far as the OP question is concerned. Everyone agrees that a '76 was a 1000.

I have 2 Sportster HD manuals that span 70 to 76 1000cc and 70 to 78 1000cc, . I owned a 72 it was a 1000. I laughed when I opened my nrw 2000 RKC manual and there were the same 30 year old photos of fouled plugs that are in these old taped up things.
