An internally-bleeding clutch piston develops a longer pull before the clutch releases, and the same for an obvious externally-leaking clutch. Like the one where you find brake fluid dripping off the clutch or front brake lever ball-end. In a case of low fluid, or no reservoir fluid, it may not release completely, or at-all. Fluid in the handlebar reservoirs should be at a minimum, half-full. The line for a minimum brake fluid level on the sight glass window is a bit-lower than that, but through experience I've found halfway is a minimum. I once had a Kawasaki LTD with its buckhorm handlebars, that to be able to get the clutch master cylinder filled properly, you had to use the centerstand, and then put the handlebars onto the right-side stop, to allow you to fill the reservoir.
A VMax has a hydraulic slave cyl for clutch operation, and if that leaks, you will find some brake fluid spotting the ground underneath the area of the operator's left foot peg, on your garage floor. I recommend the reverse-bleed to quickly and easily bleed your clutch and brake systems. I used a Mity Vac for many years, before I began doing the reverse-bleed. Now the Mity Vac sits, forlorn and lonely. Here is info on the slave cyl and how to inexpensively fabricate a tool for doing the reverse-bleed, from an implement from your local supermarket, and a couple of items from the auto parts store.
