That’s about it for external markings on 85/86 ATC250R engines unless I missed some that were worn off from age. The pictures in this thread were of take out engines (never fired). Unfortunately I do not have any clean 86-89 TRX250R engines to look for factory markings. If someone does please post up.
Maybe one day this info will help a guy that’s doing a 100% true restoration.
I will make another thread about internal engine paint marks.
