looking at the plugs costs nothing and might show a problem on one cylinder. the front lead and cap are in the firing line for a lot of water and other crap. having another identical bike makes substitution of parts a cheap (if time consuming) way of eliminating problems. snells are reputable, so won’t have skimped on fuel filter changes. fueling and ignition can be hard to differentiate from symptoms. previous models had problems with igniter circuits failing due to vibration on marelli 5.9 ecu but i’ve not (so far) heard of similar problems on the siemens units on 3rd generation monsters.
