I wanted to keep mine original bone stock just for esthetics.
When some one ask'd: OH!, what's that? I tell em the automatic chain oiler.
Wow does it really work?
Nope.
No response, point made.
I took my filter housing, clear tube up near oil tank, apart and pulled the wick and filled it w/ silicon over 2 years ago then reassembled.
Nothing gets past the wick and no drips. The unit is just there because it came that way.
It is historically correct with no legitimate purpose.
They later came out w/ a srew type clamp to regulate the flow.
I have one but never tried it.
Fill it up w/ GE silicon tub/tile stuff let sit and reassemble.
PJ black on a warmed chain lasts a long time.
Properly adjust chain and ride till warm
Spray on an old tooth brush and rub on inside/outside and both sides of links.
Let cool to chain.
Doesn't prevent fly off just limits it. Minimal wipe off the rear license plated after 60-100 mile ride.
I do the chain about 1x a month.
So far no issues.
