Suzuki JR50 Oil Pump and Clutch questions.

Hi,

I don't have a manual for this bike yet, so these questions may be
easy.
I have a 1980 JR50 that I'm trying to get running for my kids.

First Problem: If kick starting hard, the clutch slips thus the crank
does not turn.
I have adjusted the clutch by turning the adjustment under the small
clutch cover
until it starts to resist, then backed off by 1/4 turn; read this
procedure on the internet.

Second Problem: The cylinder fills up with oil from the oil pump
PDQ. Is there
an adjustment for this, or are the parts that need to be replaced to
fix this.
I can mix the gas, but would prefer not to. Also, there is a small
screw on
top of the clutch side cover that has a rubber seal; is this an
adjustment for
the oil pump flow rate? This screw is currently completely screwed in
and tight.

A manual sure would help me; is there a PDF of one on line anywhere?

Thanks for any help.

 

I'm following up to my own post to report what I found out about my
oil injection problems with a Suzuki JR50.
The check valve located in the clutch cover housing turned out to be
bad. Replacing it solved the cylinder filling
up with oil problem.

I have another question...

Does anybody know if a clutch cover for an ALT50 would fit on a JR50?
I know the engines are not the same
and have different crankcases; but they look very similar.

 

Hey I dont know if you still need help on this but i have a manual pdf you can have a copy of , as for the clutch cover alt 50 motors are jr50 motors just slight changes it depends on the year I have a 82 suzuki the last of the phase 1 bikes which is giving me troubles in starting. I dont have much experiance in jrs' but i may be able to help and you may be able to help me..
