Something Old Something New
She's not pretty or finished, but she's fun to ride. She's a 1950 Stratoliner, with other an 80cc motor and other misc. additions. I'm pretty happy with how she turned out, especially done on the cheap. I really need some ideas on a number of topics from sound dampening to brakes and front suspension. Hopefully this site will answer some of these questions.

Sound dampening- Cover the gear cover with a mouse pad. Medium rubber chunks between the fins. If you really want to go crazy, make a large volume airbox for the air filter, most of the sound you hear is intake, not exhaust.

Re: Something Old Something New
The noise I want to diminish occurs when the clutch is released, but I'm not accelerating the throttle. Basically when I'm coasting. It's a whining, screeching sound that goes away when I accelerate. Thanks. Dan

Re: Something Old Something New
By the way for all you fathers out there, my 14 year old got to be the first to get her to turn over. The smile on his face was priceless. Happened this past Sunday, Fathers Day. Anything that brings a parent closer to his teenage son or daughter is well worth a toast and a cheer!
Now if he'll only let me ride it!

Re: Something Old Something New
Grease the gears, and use the mousepad.

Re: Something Old Something New
Engine gets really hot really fast. May be normal I don't know or have anything to compare to. Runs great. THis old bike is quite heavy, may be a factor. I'm tentetive to open the throttle wide. Any words of wisdom regarding the heat?

Re: Something Old Something New
I'd pull the plug out and check out the color to make sure you are not running to lean. You might also want to spray some wd-40 around the manifold where it mounts to the cylinder and where the carb mounts to the manifold while it's running to see if you have any vacuum leaks. If the RPM changes you most likely have a vacuum leak and the motor could be running lean.

Re: Something Old Something New
Yep, sounds lean to me. Do what Fairracing31 says, then if you don't find anything, move your C clip down one notch.
