My 1975 GL1000 engine's cylinder leak down rate varies from approximately 4% to 7% across all 4 cylinders.
Yes, I have tested the individual cylinder pressure leak down rates many times over the last 8 years this engine was running.
Yes, I do believe those numbers are realistic on these engines; only when each complete combustion chamber is operationally "healthy" , though.

notes:
* 1-the Air compressor must maintain a constant supply of more than 100 psi delivered to the cylinder leak down rate tester. On this tester's gauge face, 0% = 100 psi.
(
Refer to the User Information Instructions that accompany your leakdown tester)
* 2-A compression tester adaptor hose (or other 12mm test fitting) can be utilized for leakdown testing
after its integral 'schrader' type, threaded-in check valve core is first removed. view this example-

VERY IMPORTANT! Keep fingers away from exposed PINCH/CRUSH Timing Belts and Pulleys Before and During the insertion of pressurized air into a Tested Cylinder!! AND be 100% clear the transmission has been/ IS selected to
NEUTRAL, TOO!

I trust my Kohler engine diagnostics cylinder leakdown rate tester's accuracy. Nothing fancy. Single gauge.
