Suspect ACR
Fresh 107 in the bike. Pulls hard but intermittently coughs n sputters on light throttle about 3500/4000rpms. Also idles excessively low around 800rpm. Feels like its running on one cylinder at times. Then the bike will get back on track and run strong and idle great. Im thinking an ACR(front) might be on the fritz. Is there a way I can test the Acrs? I also had a weak battery(old as bike) one morning too. Replaced it with new.
No intake leak, checked twice.
What else could I check?
Bike is an 06 street bob

ill be doing mine hopefuly this week
hope to finish up my winter motor upgrade, I always do a compression check just to see where it is for future checks, and also to check to see how equal the 2 cylinders are to check my cam timing. I usually do one check with acr plugged in and one unplugged . cant remember if I get an engine code when I unplug it for a no acr test. easy to clear I I get one. just go through code checks on speedo using the reset odometer button. think I usually get 25-30 psi less compression with acr activated
