Anyone ever run these kevlar discs? if whats your opinion on em?
I could get the standard cork and aluminum ones too, but im curious about these.
It would be cool to know some first hand info about performance....
thanks,

Great kits for drag racing or in street racing setups where the need the extra plate biting, stronger springs high engine torques etc... but for street use, stick with the OEM/reproductions...
They they followed up with "They worked for 30 years in the old girl what makes you think they won't work now...."
Then there's this... Pending your age, left arm/hand fatigue.... These old beasts aren't hydraulic clutch, well at least my KZ900 isn't, and with heavier springs this will be harder to pull...
Just what I've learned anyways....

But ehhhh, my hands arent too old, i can handle a little stiffer spring if it means a little better bite.
I'll probably end up sticking with a good quality standard kit, and maybe some stiffer springs.
any recomendations?

Start lifting weights and squeeze a tennis ball with your left hand to build up endurance....

Im talking about a brand of clutch kit someone might have had good results with......not my hand.
I turn wrenches all day, i dont need to squeeze a ball.

Along with OMR's "Start lifting weights and squeeze a tennis ball with your left hand to build up endurance...." I'd say you need to start carrying a spare clutch cable along with the tools needed to install it at roadside.
No offense intended, but we're talking about a KZ550. Even with very spirited riding my original '77 KZ650 clutch went 36,000 miles before it needed to be replaced. I would think a KZ550 stock clutch would last at least that long if it is kept properly adjusted. It's your bike & money, but I wouldn't get too carried away with visions of higher performance from heavier clutch springs. My $0.02 Ed

Alright, first of all thank you guys....
I know the clutch is slipping because the adjusters are in as far in as they can go without exessive slack in the cable.
unless there is another adjustment?
No offense taken, i just want my bike to ride good man. And it would kinda blow having to lift weights to have the strength to work the clutch.
Ill get er going
