Is there a site I can go to so I can figure out what year motor I have.Engine#KZT00AE025777-it's a 903cc motor so I suspect it's a '76 but would like to know for sure.Thanks Jerry.

According to Zedder.com you should have a 77 KZ1000 A1 engine.

Is 903cc embossed on the front of the jugs? If it says 1015cc, then the entire motor is likely a KZ1000A1. If not, then perhaps someone mated the top end from a Z1/KZ900 to a set of KZ1000A1 cases. :blink: :huh:

Thanks guys.It had me confused.The motor is in a Rickman frame I bought and it came with the 28mm carbs in a box of parts.The bike was being built by a Kawasaki enthusiast to race in the vintage endurance class.The guy had a ton of parts,so the jugs to cases idea makes sense.He died of cancer before he was done and his wife sold it to a club member,and I bought it from him.Thanks for the info.Jerry
