066 serial number

[nilzlofgren]

I believe I found serial numbers to my 066 bottom end stamped into the case running above where the mounting hole for the inner bumper-spike is located. My problem is, that a piece of the case is broken off at the mounting hole, which took some numbers with it. the numbers I have are: "134990" I believe I am missing three numbers. I see some serial numbers that end in "066" Is this the case for all 066 serial numbers? Also, anything I can figure out from "134990", besides where it is made? thanks

Approximately a 1996 model?

The last three numbers can be anything not just "066". The first few numbers are all you need for the rough model year.

If you split the crankcase, there is a second "hidden" set of serial numbers on the inside edge of the clutch side crankcase mating surface.
