No problem
The brake and clutch reservoir needs to be kept topped up to the level marked on it with DOT4 brake fluid (DOT 3 would be not be a problem, DOT5.1 is also good. Do not use DOT5 unless you really know what you are doing and are willing to completely clean out the system and make sure that all lines and seals are compatible with it!)
The engine oil is 20W-50 V-twin oil, preferably synthetic at least once run in. I've been using Motul 7100 4T 20W-50 but others are available. I think in all but the early cars which have a small dipstick on the filler cap there is a level indicator built in to the tank itself; the level should be checked within a few minutes of stopping the engine not with it stone cold and been sitting for days.
