Now, that's a healthy sounding engine! I like it!

Thanks for the advice KC's Builds. The bike is running pretty good right now. I did not think about the carburetor level, and yes. The motor is mounted with a screw through the frame. We don't have chain jumping problems and the motor is bolted on pretty solid. The things you pointed out make perfect sense and something to rethink. I appreciate the advice and will consider making some changes. Thank you!

KC,

You obviously don't have much confidence in the Huffy Cranbrook. How do you think the Columbia compares overall? Jim

I seems like a pretty solid bike so far, it weighs considerably more than a Cranbrook. thicker steel tubes I would assume.
The back hub seems fine and actually had good grease in it so I guess we'll see.

Thanks for the advice KC's.

That's good news, they aren't much fun if you spend more time fixing them than riding them ;-}

The motor is mounted with a screw through the frame.
We don't have chain jumping problems and the motor is bolted on pretty solid.

What happens is vibration will start causing the that bolt to wobble out that thin frame tube making the hole bigger and bigger until the frame fails as it is hold a flat plate to it's round surface.
You could put the mating piece from a muffle clamp in there to help, but I think you would better off using a Sick BikeParts.com front mount and wrap your frame where the hole is with some good sheet metal to help reduce fatigue at the compromised frame section.

You are very welcome, ride safe ;-}
