Anyway, found one in Ontario and rode it home.
I rode the 1500kms home in the rain with NO issues at all with the bike. It was amazing. I get into my home town and at one point come hard on the throttle a bit in 1st gear and it it was slipping. The revs were going higher but it wasn't engaging.
It was like a transmission slip or something. I took it for another ride last Sunday and didn't come on to it that hard but at one point had to pass a vehicle and when I came on to the throttle a little harder it slipped again in 5th gear.
I am not sure what may be causing this. The bike only has 26,000kms on it. I see no signs on any leaks around the boots of the drive. I also see no signs of leaks around the clutch slave cylinder.
One thing I do notice too lately is that when I go over bumps it feels like a bad shock or something is loose under the bike. I checked anything that could be loose without putting it on the stand. (that is in a box that is coming in a week).
Clutch seems to work fine and there is sufficient pressure from what I feel.
Anyone have any ideas of what to check for? I did order a new slave cylinder anyway as it seems it would be good to replace that.
Thanks for any help. :-)

Agree with 908/930's comments and suggestions. My 2002 prep's clutch splines failed at 18,935 miles.
Possibles:
1.) Faulty clutch slave seal resulting in an internal (not outwardly visible) hydraulic leak which migrates through the hollow input shaft saturating the friction disc on the opposite side with slipping being inevitable. On a properly maintaned machine, a low clutch side reservoir fluid level is usually a
telltale sign as well.
If, mechanically capable with a modicum of aptitude, simply remove the starter and look for evidence of
moisture,
not dry friction material
dust.
2.) Driveshaft portion of concern is a
two component affair with an elastic isolater membrane separating them. De-lamination causes a loss of power transfer. Usually, when these fail a distinct burning rubber-like odor due to friction is noticed accompanied by a coarse whirring noise.

3.) Transmission input shaft to clutch hub spline failure.
When these fail it is pretty much instantaneous. One minute you're cruising, the next - not. This failure is characterized by a distinct raspy rattle while at rest with motor running,
in gear and clutch engaged.
For 2 and 3 the rear of the bike must be raised enabling the wheel to spin. Engage any gear, preferably 3 or 4. Grasping the wheel at 12/6 or 9/3 O'clock position turn, and and take note of any slipping or freewheeling.
If you cannot spin the wheel the focus reverts back to a hydraulic fluid contaminated clutch disc.
A small diameter seepage, or
pending clutch slave fault indicator hole can, (and should) be drilled into the side of the transmission slave location for simple monitoring at a glance.
You can use the search function to find any number of threads on this.
Good luck.
