CR8E is the correct plug = It will hate CR9E a lot. No IX they hate it. Just keep it basic CR8E , if it won’t run on a factory CR8E plug, there is bigger issues likely compression problems and valves too tight.
Yes the stator & RR will make the ignition coils go funny at times
There is a guide on the forum called “Battery Test” , follow it and there is a picture inside on how to test the Stator , Coils , Caps and report the figures here.
Either way get the engine compression checked and clearances checked it will save a lot of headache later
Upgrading fuel parts just makes it easier to send fuel to carbs and run a bit smoother at higher gears if the bike is fuel starved before but as before focus on the engine first.
