Lesson Learned: You can't judge a book by its cover!
I purchased the bike without starting it because I wanted to check things out. Well, one thing lead to another until it has now become a mechanical nut and bolt restoration. I just pulled the crank and to my amazement the slinger was full and the awful sight of the snail trail of debris has enter the crank pin. Amazingly enough, the rod bearing still feels smooth. Looking at the bike and the documentation and history I would never have seen that coming.
What is with that slinger design? You can see in the picture that it only allows capture of 3/16" before the debris reaches the crank!! Before disassembly I had assumed it must be at least 1/2"
I sent the head and cylinder to Max in New Hampshire and they are going to do a first over bore with new piston, and I am sending the crank for rebuild and balancing with the new piston. I will let you know what condition the crank is in!
