Atc350x mk136

[3or4wheels]

I found written on the crankcase halves in permanant marker "MK136".It´s on the outside, on the underneath,hidden by the engine skid plate.
Any ideas what this could relate to ?? Cheers

Hello

Might simply be from the engine final inspection at the factory. I have seen such things before. Salvage/parts guys also often mark their parts with a yellow paint marker etc.
