I have a 1984 R100 something. I have looked at engine numbers on line until I am cross eyed. On the left side of the engine are there are two numbers. 83346285 and below that DBMS 098042A3
The Calif. title lists the first number as the engine number. I cannot find any such number the Phil Hawkley's BMW page or anywhere else. It seems all the R100 model start with a 6. Has anyone run into this before? Does anyone know where to find these identification numbers?
