I would say most OEM wet clutches can make it past 25k without problems... but
it really depends on the rider. If you ride the clutch a lot it will wear out
sooner. Also a heavy load on the bike can wear out a clutch faster than a light
one. I have seen some people put 50k on their bikes without needing a clutch
and I've seen others burn 'em in 5k. But If you are using motorcycle oil ONLY
the clutch shouldn't slip because of the oil. If it still slips it is probably
time for a new clutch.
*The clutch kit should include all the discs you need.
Springs... many people change to stiffer springs because they help the clutch
grab harder and as they soften up over time they will still always be harder
than the OEM springs. The only down side to stiffer springs (if any) is it puts
a heavier load on the clutch cable which makes the clutch lever stiff and tires
some people out. Also a heavier load on the clutch cable can understandably
wear that out faster.
I noticed my clutch slip on occasion in high rpms on my 92 CB750 after about
18k but I have just been riding it that way... the bike is at 25k now and it
doesn't seem to be any worse. I do like my bike to be running perfectly though
so I admit it has been pestering me in the back of my mind for a while. I got a
KG clutch kit + KG springs a little while back (I do a lot of sport riding)...
they had happier ratings than barnett. I was going to put it in next oil change
but that turned into the next and the next one. I was finally going to do it so
I checked my manual and it turns out I would need a special honda tool that
cost's $60 at the local honda shop. Turns out the labor to have the dealership
do it is only $90 so I am just going to pay them to do it and call it a day :p
If you are not racing your hawk through the canyons or on the track and do not
desire a more aggressive clutch then an OEM replacement clutch kit + OEM
springs are the way to go because they will no doubt last the longest.
If you seeking some middle ground between stock and very aggressive then go
with high performance springs and OEM discs or visa versa (if you don't want a
stiff lever).
OOH! You will also need a clutch cover gasket so don't forget to order that!
What bike is this for? How many miles?
