Here's where I'm at for those interested. I completed the installation of
the Oilite bushing on a Chinese 4 stroke ebay kit and did some initial
testing. So far it looks like a very promising improvement over the
greased bronze bushing - no drive problems at all. I don't know
how long it will last until the bushing goes dry. Some users swear
by these Oilite bushings. All I can do is continue testing and then
inspect the parts after about 100 hours, and report the results. I
intend to make a video of the drive running to show how
stable the clutchbell is when running.
On the bearing solution, I am at a crossroads: The small Avid sealed
bearings I purchased did not fit the motor shaft, although they were
intended for a 15mm shaft. Some small amount
of material would have to be taken off the shaft to get the
bearings on, and I'm reluctant to mod the shaft. On the needle roller
bearing, it is a slip fit over the motor shaft, but I am very concerned
that the keyway groove will interefere with its operation. I could also
envision how the groove would collect grease from the bearing,
and ultimately all the grease would end up in the keyway groove.
It could be that the sealed bearings are the best solution, and on
the plus side, I now know how to easily install them on the drive.
So overall, right now, the best solution seems to be the Oilite
bushing. It's an easy fast mod, and maybe, it could last for a long
time before it has to be re-impregnated with oil.
