I don't think quickly releasing the clutch lever constitutes abuse.
This may be a case of OE (operator error). I might be used to bikes with a much higher power to weight ratio. I've had the bike out a bunch lately, she pulls right up in 1st or 2nd using the clutch. Problem is in 3rd gears on up, she seems to want to be 8k+ rpm and up to lift the front wheel using the clutch. I'm more comfortable keeping the revs low for clutch wheelies. My poor clutch performance is in 3rd gear while trying to loft the front wheel with the bike cruising at low RPMs. Crusising in 3rd at 4k I'll slip the clutch, grab some throttle and release the clutch. Nope she won't pull up and the motor slowly reduces RPMs as the clutch continues to slip once released. I'm still thinking a better clutch would just grab and the motor RPMs would drop instantly, or the front end would come up.
If I get the RPMs up to 8-9K it feels like the front will come right up in 3rd using the clutch, but at this point I'm going way to fast and I'd rather keep the revs low for slow speed wheelies. What it boils down to is I'm used to dirt bikes, I want my V to pop up like a powerful dirt bike. Time to gear down.
As far as abuse..... My dirt bike is 3.5 years old, coming on 3k miles of the roughest conditions imaginable, lots of slipping the clutch to get unstuck from everything nature can toss in the way, hills, trees, mud, you name it. The biek still runs great, valve shims are original and still in spec. The clutch works perfectly (and grabs instantly ALL THE TIME), way better than the V's clutch if I may say so. I've been posting about the V's clutch since I got it home, it just doesn't feel right when I'm hard on the throttle. If Kawasaki's are so fragile that romping on the throttle and slipping the clutch here and there for some fun will ruin the motor (which I strongly doubt to be the case), maybe my next bike will be another Yamaha.
Just messing around, I really like the V. Just wish the clutch grabbed and held better, would make for better 1/4 mile times as well. There are professional reviews that claim the V's clutch is sub par, and I'm afraid when it comes to aggressive riding, I agree.
