ehhh....Sprinter's carb is hell a lot mysterious...
i suggest you just set valves, clean air filter, change engine oil..then do oiling all mechanical wires..(clutch+accelerator+front brake wire) check rear wheel balance including rear brake)and after completing all this...all nut bolts of bike..(wheels, main bolts what connects engine to frame (Body), rear swing arm..handle bar..shock absorbers) etc..
and by the way carburetor needs no cleanses until it hurt..so u can check it every two three tunings by some mechanic...dont open it by your self!!
