    Here is a fun one… the oil seal that I removed has a hole drilled in it. Please ignore other damage. That seems like a terrible idea. That defeats the purpose of yhe oil seal a bit. Water could get thru that and thru the bearing and into the crank case. Why would someone do that?  This KG7H was raced for years so sometimes I find racer tricks… but this one? I plan to not drill a hole in the new oil seal, just curious about this finding.
