I recently picked up a 1949 Hummer basket case that I'm looking to restore. My research tells me the cylinder bore on this motor is 2.125 but it measures at 2.105. Huh?
We've honed the cylinder out to 2.120 to clean up a groove left by a ring sticking out of the piston, but I can't seem to find out what the actual standard piston size is? .010 - .070 over,(over what?)
I've tried contacting the 2 places that i've found that sell hummer pistons but neither answer the phone or return messages. Any help on this would be greatly appreciated!
I also can't identify the year of the frame. The fork and frame part numbers are 45692-53 and 47454-53. The only info I found is that these are simply part numbers?
Thanks
