Ok thanks. I was confused by the pull a fuse suggestion I received. I thought the valves were mechanical. Still do they need to be disabled somehow to correctly preform this test?
As for the spark disabling ,All I did was remove them. The fuel was not disabled. No on/off valve on the tank because its fuel injected. But if you think that not turning it off has affected the test let me know. Then pulling a fuse is an option to shut off the fuel. If you have the fuse number just let me know. Or I'm sure its listed on the bike.
Remove the system relay from fuse block to disable ACR. IIRC, system relay is #11 in fuse block location; the procedure is in the service manual. If you plan on working on your bike; get one. Don't worry about getting the motor to operating temp; CCP = "cold" cranking compression. If CCP is low on "cold" motor, then you run the test on a "hot" motor to see if there is a significant difference. If the top end is in good condition, you won't see much difference.:s If there is a significant increase in CCP, rings are not sealing. If there is a significant drop in CCP, time for a leak down test.
As for your plugs, unless you do a "plug cut" it's hard to judge. Once you do the compression test, ride the bike, let the motor see some high rpms. When you roll back into the garage, clutch, engine off and pull the plugs. True plug cuts are done with new plugs and the motor is shut off in the condition one wishes to read the plugs, usually WOT. Install fresh plugs, get the motor up to operating temp and run her up to near the rev limiter, say in 4th gear. Clutch, kill the motor, pull to the shoulder and pull the plugs. If one wants to check AFR at cruise, same procedure. New plugs, operating temp, cruise for a bit in top gear, light load/throttle, clutch, kill motor, pull to the shoulder, pull plugs.:s
