Where's the dipstick?

With the clutch basket directly below the oil fill opening on the Vulcan Classic/Nomad/Mean Streak there's no way to fit a dip stick. Instead Kawasaki has provided an oil sight window on the right side of the bike. Checking oil level is made easier with a "mechanic's mirror" which is a small mirror attached to an extendable arm (a couple of bucks at any automotive supply store). Sit on your bike and hold it level while you look in the mirror at your oil level. If you have a helper have that person level your bike while you check the oil level.
