Motor Year
« on: January 27, 2010, 02:34:39 AM »
I have an 86-88 KX500 motor that I am trying to figure out the exact year on. The motor number is KX500B100-4914. At first I thought it was not an 86 because a newer style boysen intake bolts up. Boysen lists 87-04 KX500 years for their intake. But kawasaki parts diagrams show 86 and 87 intakes and gaskets having the same part numbers. 86 & 87 appear to have the same port layout with 88 as its own design and then 89 and up according to la sleeve. I have not been able to find a motor number database anywhere. Thanks for the help ahead of time!

Thanks Stewart! Is there a public database that you use or do just know from your motor experience?
