Re: I'm Restoring a late 40's Rocket - Then comes the motor....
They are important. My dad bought an old Clipper from a guy in his trailer park back in the 70's. It was hard to pedal so we went to a junkyard and found a smaller front sprocket. Lucky it had an even number of teeth because I had to grind every other one off to fit his skip tooth chain. He used it for exercise until he got too old to keep his balance and gave it to me. I was stupid and sold it to a friend and have been trying to buy it back ever since.
