The Warrior is a hot rod and doesn't use synchromesh because it would rip it apart. It uses a heavy 5-speed close-ratio multiplate wet clutch system. With no synchromesh it'll shift between gears differently than your old bike, or your standard trans car. You'll feel it go into gear.
When its cold, and when you make that first shift when its warm, it'll often jump a little. Its natural. Yes, there is a spot where it's jumping too much, which is the signal to adjust your clutch cable. That art of cable adjustment isn't hard to pick-up, just go for it in while at home (not traveling) and make a few minor adjustments you'll catch on. When it needs adjusting that is (if it ain't broke don't fix it).
I've had my clutch cable so perfectly adjusted that when its warm it shifts almost silently. Then I bang the gears a few times and its back to being a little jumpy but tolerable. When it jumps with a swift loud thudding 'crack' its time to adjust the cable. Ride with some other Warriors a few times you'll get to recognize that sound 
When adjusting the cable, your goal is to have the little case lever (shown below as Item 5) sweeping its full range of motion especially fully releasing all tension so the clutch plates can seat fully or they will slip. At the same time strive for about the thickness of a nickle gap between your clutch lever and the lever housing when you let go of the clutch lever. It might look better with no gap but it won't run better that way!
There's a ton of 'ink' here about how to adjust, do a search you'll find plenty of opinions and they almost all work fine.
These happen to be 2007 model year diagrams but suffice for this conversation - but ignore part#'s as some differ.
Note Item 15 below is the mid-point clutch cable adjustment, Item 14 is the lever end adjustment.
