[/IMG]I bought my first China girl back in November and recently blew out the main crank bearing, But this is not a major issue to me as my plan has always been to rebuild the China girl using the highest quality bearings and seals and balancing the engine to hopefully achieve a level of quality and reliability that is acceptable. I have a spare engine that I plan on running while I rebuild this current engine. I know 4 strokes are more reliable but I really like the appearance of the china girl for my build. I'll let you know what the results are after a few miles are achieved.
