Schwinn Skyliner With 4 Stroke

This southern fried four stroke Schwinn Skyliner was built by my good friend Allen in Macon, Georgia. Have a look "four" yourself. He reports smooth sailing after adding some gear oil to help smooth out the clutch chatter.

So, where did he get the 3 piece crank?

I'd say the four-strokes are coming of age.

He got his cranks from a guy in AZ who only had one available.

Josh,how much gear oil do you put in the gear case and were do you put it into the gear case?

Josh,how much gear oil do you put in the gear case and were do you put it into the gear case?

We have found that a mixture of heavy gear oil and stop leak works best. Use about half and half. It only takes about 3-4 ounces. You can pour it right down the hole on the top of the gear box where the engager lever extends. See the picture below. The stop leak bottle shows where to add.

You may notice some leakage from the gear box as the gasket wasn't designed for wet use. To eliminate that you can use a waterproof form-a-gasket or even some silicone.

The clutch will slip a little at first, but after a short time it will burn off any excess and should be smooth and chatter free. You can add more when the clutch starts to chatter again.
