Just pulled crankshaft from my '78 RM 100 and noticed a few things. There were three very small pits in the outer surface and it looks like at some point some piece of junk cause some scratching to the surface. Those issues seem rather minor to me but I am unsure. Also, there is a indentation along the edge and I am not sure how serious that is. Whatever the cause it looks like the same piece of junk may have caused some minor pitting in the crankcase in one spot. Is that a major issue? I am attaching photos. Bought the bike for $100 in pieces and have been gradually tinkering with it. When I bought it the motor was not seized. The threads and end of shaft on left side are gnarled and I am not sure they are salvageable, but thought I get some opinions. Thank you!
