its a 550 kat not a 650.
GS550 manaul is a better bet.
Bog basic UMJ bread and butter stuff , tough as old boots, recomended.
Weak spots.
Regulator pops
Generator pops
Battery goes pops.
General electrical rot.
Drain and check the oil, people abuse these bikes on the grounds their tough, Shims prob havent been done since Adam was in short trousers. Sprocket nuts come loose. Bolts snap in the rocker cover. Head sticks on. Oil leaks. Seat base rots (tho the Kat may be plastic). Horrible headlight/indicator switch needs taking off. Brakes seize. frame paint is rubbish, shocks are crap.
Engine makes the Guzzi motor look underbuilt.
Good bikes.
IF the bike is running prob 99% of this is already sorted.
