Hi Richard,
5651096 is a 100hp 912ULS made april 2008. It was supplied with green valve covers. It was delivered to the Czech Rotax dealer. It was never registered by the owner(s).
If you want more verification I can double check the serialized parts such as crankcase, ignition modules, gearbox etc.
Here is the factory config:
without fuel lines
UL2 I=2,43 with clutch
without vacuum pump
with green valve covers
without mech. tachom. pick up
without external generator
without air guide baffle
with std. temperature sensors
with nipple conn. for oil pump
