Re: Maintenance ?'s
drain the coolant out of the overflow bottle and the radiator. flush it out with either water or some prestone coolant flush (or other brand) then fill it back up. get the engine warm with the radiator cap off (it'll suck the coolant down) and top it off. I did my 929 last sumemr and used the Honda stuff. Did a friends zx7r,I forget what brand we used though, might have been just regular old prestone.
way too many choices on oil, just make sure its a good quality one. filter I'd just stick with the good old honda one (the 2 deez mentioned are also good filters).
if you can't convince them, confuse them.
