hand engraved numbers on motor

[daves86vmax]

my 86 has various series of numbers and letters hand engraved in about 6 places on my bike.Does anyone else have these and what do they represent.

I have noticed them on my 97 also. Must be assembly line check point sign-offs. Looks like they were made with those small hand held vibrating engravers.

Most of them are going to be numbers used for setting bearings, or other shim thicknesses.

They are numbers for when you need to replace the main and rod crankshaft bearings along with the balancer shaft.
The numbers engraved are used with numbers that are stamped on the crankshaft and balancer shaft once you use a specific formula than you know what color bearings you need. Hopefully you wont ever have to do this. Been down that road to many times.:bang head:

Better put down your backup card. I need to check when I go to the shop today. I won't rummage through the engines I will just check completed bikes.
