As above, I need to locate the engine number on this Rotax Twin spark motor, looked in the obvious places to no avail, I have a part number stamped into the flat behind the gear stick bottom LHS Crankcase with a date stamp of '96, where the Haynes manual says it should be, but the GS Dakars also use that location. Read on a thread it should be on the back of the motor facing the rear wheel, but thats not obvious, any help gratefully received as I need this to register in the UK. HELP!!!!!!
