Hello,
First post on this great site! I have a 59 R50 with close to 90,000 miles on it and put first over pistons in two years ago. Slingers were done about 15 years ago when a crank needed replacing. That was 20,000 miles previous. My question is if there is a way to check the output of the oil pump without pulling the pump and checking lash etc. to ensure enough pressure/volume on a running bike?
Thanks

Oil pressure check

What I've read on another /2 forum is that the easiest way to check for pressure is to remove the valve covers and start the bike. Have some newspaper, etc., to catch the small amount of oil that comes down the pushrod tubes. If oil is making it to lube the rocker arms, you have enough pressure to the rest of the system. It should only take a few seconds...

As for volume, make sure you have enough as measured by the dipstick.

Oil pressure check

Thanks Kurt. I have oil in the covers but no appreciable amount runs when motor running. I know there used to be plenty. Even revving the motor there is still only random drops. Looks like I need to investigate further.
Cheers,
Ron
