Hi I am restoring number 786 motor 917 . It has what looks like 20000 miles on it. Last plated in 1985. It is running really good but it needs a complete restoration. This site is a great place to gather information . Every one involved in this site should be very proud of it. This forum give people like me confidece to take on a project that may seem overwhelming, gives people confidence that they can get help in areas the have little experience . I Had a 1969 sand cast in 69 and being young and foolish drove it to its demise in 1971 by throwing a chain throug the crank case. Pached it with a beer can and some sort of glue. I topped up the oil but it could no longer stand the thrashing and pushed a extra hole in the case with some sort of engine internal . What a shame, I feel as bad about it today as I did then.
