I had the pin that holds the top ring from rotating come loose & wreck the piston & cylinder :-(
the engine had maybe 1000-1500 miles on it & when I took it apart I noticed a little play in the lower rod bearing so I split the case.... when I did I noticed that the main bearings were generic & in pretty bad shape
Im going to take the crank to my machinist & see if he can do the bearing & machine off some material from the pin side to help ballance it
Ill use all japanese bearings & I was even thinking of using an iron sleeve in the cylinder
I can see the # on the mains I think they are 3202 (common bearing) the lower rod though may be harder
thanks for reading
take care
