Compression test with acr's
I installed 555's in my 12 SG. Got the infamous knock intake pulse at idle when warm. Was told by all its normal but just wasnt satisfied so I double checked everything install wise pushrod adjustment so on all is good. So I threw a compression test on since I have 1000 mi on her just so I have reference for future as I do the same with all our race bikes. WTF 130 rear 110 front. Now im panicing. Now im thinking the knocking sound is a valve. So I do a leakage test. Both cylinders perfect less leakage than anything I own. WTF again. Duh the acr's. Unplug them do another comp test and both cylinders exactly the same at just over 185 lbs on my el cheapo gauge. Now im convinced the sound is normal although I think a little tuning will iron it out some as the idle is pretty eratic I dunno but guess I will have to learn to live with it or mount the aircleaner on the back of the bike somewhere where I wont be able to hear the sound lol
