The issues that remain...
Clutch slave cyl has become more rare. Seems mots people have an aftermarket installed. Fuel pumps and filters have some occurences, I believe maintenece could include filter replacement. Also Clutch master cyl have failed on some riders. Rear brake master cyl a few times, the key barrel gets worn, the swingarm slide needs attention or replacing the securing bolts with longer ones passing through. Clutch lever wears and need replacement after some 70k kms. A large service including swingarm bearing replacement, steering bearing replacement, suspension oil etc. Nothing else I can think of. If loaded and riden hard, there are some occurences of broken rear subframe.
