I was having excessive I burned gas plus a ticking noise from my engine.
pulled the head pipe flange .... the nuts were all loose and even one was totally off..... the specs call for only 15 f# . Check them at lest once a year. My 2018 Springfield had 16,000 mile on her when I caught this problem.
stay safe my friends.....

Were you also having any issues with engine vibration as well?

Basic motorcycling 101: the heating.cooling cycle of the exhaust combined with the vibration from the engine can cause the exhaust nuts to loosen. I check mine every oil change.

No engine vibration. Just that damn pinging noise...... 😳

Not being very mechanically minded, how hard is it to check/tighten the header bolt/flange nut on the 111?

I torque my exhaust flange nuts at installation, first heat cycle, 50 miles, 150 miles, and lastly at 500 miles. The gasket material compresses at each heat cycle of the engine until it finally settles.

It's fairly simple. You have to remove the covers (two allen bolts, two guide pins) that cover the exhaust flanges. The rear requires a socket, extension, and torque wrench. The front requires the same tools, plus a u-joint or swivel joint adapter.
