ENGINE INFO PLEASE

hI GUYS, i HAVE TWO BIKES AND Im curious about the engines. how do I know what engines I have. The one kz1100 is an 82 on the front forks it says engine motor KZT10A ser. no JKAKZBA11C. tHE KZ1100 SPECTRE says KZT10D SER NO. JKAKZBD1. Can I change parts on these two engines. I see the carbs on the spectre and the 82 KZ1100 look the same but tonite I see two hoses coming from the back of the carbs going to the ground ON THE SPECTRE the 82 red KZ doesnt have tbose. Thanks again

What are you trying to change? Are you trying to cannibalize one bike to make the second run? Take pictures of both engines from the left side and post them. The engine #s are on the engine itself near the oil fill cap.

Thanks Gunny I will Do that. SEMPER FI
