Another Myth Shot To Heck
For years I had heard that the Chinese version CN-250 had smaller main bearings than a Helix engine and I just figured it would mean a less sturdy motor that wouldn't last as long. I finally found out today what that difference in size is. A Honda motor has bearings with an outer diameter of 72mm, a Chinese has 68. You know what that works out to? How about 4mm or all of .156 of an inch. Somewhere between 1/8 and 3/16 of an inch. "Wow! What a huge difference!", he said sarcastically. Isn't it amazing how the Myths of Chinese Inferiority just keep tumbling. My crappy main bearings are 2.677 inch, a Mighty Honda has 2.834 mains.
I think I'll live with that.
