Plus one for vista. I'm waiting on a nice day to drop my bike off and get thee valves checked. Because that is out of my repertoire. And because I'm lazy and it won't add many more hours to the service.... I'm also having them do all the regular stuff that I would normally do. But if you're just doing an oil change, you need as little as a 4 mm allen, maybe a 6 too, a screw driver, and pair of pliers. drip pan would help, but a small mop bucket works just fine.
