Snow and sleet is a good time to go through EVERYTHING and do it yourself...then you know for sure what has and hasn't been done! Buy yourself a Haynes manual, or get the service list/maintenance thing on the web. It has everything but is a complete PITA because it is on the confuser....I can't take my confuser out to the bike with me...so I make notes, and take them with me instead! Sheafs of paper. It makes the world go round.
If I buy a new bike privately (not happened for some time) I will give it a complete service of everything that needs servicing, even if the owner said he did it yesterday. If he changed the oil, then it has had a nice flush hasn't it...and for a tenner, what price piece of mind.
Change the engine oil
Gearbox oil (use a good one - I like 75-90)
Back wheel oil (I think people call it the crown wheel and pinion....but "back wheel" doesn't take so many teeth spits!)
Change the clutch and brake fluid (or if you are not confident to do it yourself, get it done).
Wheel bearings - give them the shakey test.
Why did it have a new front wheel? Big impact with a pot hole?
Brake calipers. Get them pads out and check the pistons trundle to and fro. Clean the pad pins and treat to a smear of copper slip.
Air filter...is the big box under the seat. Undo 3 screws and lift out the big, round paper concertina. Change it - don't even think about cleaning it. Just chuck it and put a fresh one in. Agan, they are only a tenner, posted. I buy 4 at a time (2 bikes you see...one in use, one on the shelf).
Spark plugs. get some new ones in there (unless you can see they are brand new).
Tyres....got some air in them? That's good.
Really, if you go through the entire major service yourself, doing a bit at a time...it whiles away a whole day, won't cost any more than having the bits done by someone else and you learn a lot about what lives where on your new bike. Very satisfying....until you come to the electronic bits. Then it is like trying to use a confuser or a mobile phone, some can and some can't.
