Clutch oe or aftermarket

[not a biker]

the clutch slips under full power on my 1150. i think i will just install new suzuki clutch plates. is the cost about the same as a barnet kit with new springs and plates. i am not interested in racing and i do not want a harder pull on the clutch. also maybe high performance clutch might chatter on take off ?. thanks.

How many miles on the bike?

Chances are that you only need new springs, but measure your current plates to be sure.

Try replacing just the springs with new OEM clutch springs. After a couple of decades, clutch springs sag -- this is a common problem. Simple, easy, and cheap.

Don't forget to order a clutch cover gasket while you're at it...

Yea, what the other guys have said...

Measure the clutch plate thickness - the service manual has the spec. for minimum thickness. As long as the plates are thick enough there is no value in replacing them.

[Dogma]

An addition to what has been said... Stock springs on mine, and they still slip at high revs. All the disks are within thickness spec. and have been sanded. Sanding helped for a while. Someone here suggested checking for cone warping of the disks by reversing the orientation of half of them and stacking them up again. I haven't tried this yet. The next thing to try will be new plates, I suppose. At any rate, it should work correctly with new stock springs, and they are really cheap.

If the springs don't do it and you do decide to replace the plates, avoid the Barnetts...they won't do anything for you, might hurt...

OEM are good, or if you want something a little tougher, try FBGs...
I use them in both my drag bike and my street bike...

Schnitz sells 'em...$72 for a set of 9...

thank you very much for the advice, i am the 3 rd owner and the bike only has 12,000 miles on it. i doubt it has been run hard becouse the guy i bought it from had it from 1990 and the carbs are still stock. not even jetted. week springs would be the last thing i would have thought of. from the number of folks saying the same thing i guess you are right. i did a 3 rd gear roll on and just as the bike hit 7,000 the tach shot up to 9,000 in a instant.
the bike has a pretty hard clutch pull already . will new stock springs really help ?

1150's have a heavier lever pull than 1100's.
if i was you...
put 9 OEM suzuki fibers in it.
bead blast the steels.
and this last bit of info is up to you..
run 3 of your stock springs and find/purchase 3 gold barnetts or something similar.
if you never power shift or run this bike hard then install 6 NOS suzuki springs.
(think about installing a NOS suzuki clutch cable also)
make sure your cable is routed correctly and working smoooothly, nice gradual bends ect..nothing pulled tight up against the frame.
loose is good for cable routing.
your fibers are hard as a rock i bet, even if they measure ok they still have no grip and will not stop slipping unless you put a bunch of spring pressure against them.
paul gast plates are ok on a slider clutch but i think there way to agressive on a live clutch for a street or strip bike.
the information i just listed is from 20 years of doing this stuff on GS suzuki's.
if i tell people on this board information... it is because i have found out this is what works best for me and numerous others i have done it for.
do with this info as you choose..

you the man
no power shifts on this bike. just roll on power with speed shifts. cuzz the bike is 25 years old and i am 61 years old. now back in 82 on my new GS 1100 i was a crazy man

I had tried the new springs route with additional washers only to find out the fibers were so old and hard I pretty much wasted my time, even with scuffing the steels.

New OEM fibers and the she doesn't slip and ounce. I also wanted to mention that the engaugement is smoother as well.

For your clutch nut needs, you can go to APE for the ultimate clutch hub nut. I just used a new one from Suzi.

I also wanted to mention to check your basket springs for play when you have your clutch assy. all apart.

New FBG plates, 3 stock springs & 3 Barnett springs. All else fails, I have lock up clutches for sale & then you can use the WEAKEST stock springs you want! Ray.
