Just do a general once over before even making an offer. Some things you can look for to know if it was taken care of is to ask for any service records, .....
Ask how often the oil was changed,
CHECK THE AIR FILTER!!
Ask how many hours are on it and compare that to how the parts look like how worn the sprockets are, the grips, the tires, the chain and guides, the rear carrier and if the engine is stained with dirt at all
Check for any engine noises,
Check the radiator for coolant, (it has saved me before)
Have the guy change the oil in front of you and inspect the oil for any shavings. I cant tell you how many times that has saved me from getting another headache.
Also, check how the clutch feels on acceleration, no slipping, smooth
takeoff and shifting
How the bars feel turning,
Check the suspension action
Make sure it goes through all the gears and that it shift into neutral easily)
Check the clutch and brake cables,
Make sure it fires right up COLD
and make sure it IS
cold and not warmed up before you get there.
