Hi all I have been spending a bit of time trying to find my serial number on my mid 80s Classic 50.<br />I can't seem to find a whelsh plug, or a tag on the bracket.<br /> I found a few numbers above the fuel pump that were stamped in , but they are un recognisable!.<br />I've been serching again and removed the CDI box Unit and under it was an aluminium plate, under the plate I found a 7 digit number cast into the block 863-8930. Is this my serial number or just the block part number??????
