Clutch slipping or transmission issue?

So I just spent over a grand this year on the bike, new rear tire, chain and sprockets, and other misc. items. I've taken the bike out probably 6 times so far this spring and the bike has been running great. Today I even went for a ride and things went great. Then I wash the bike, and decide to take it for one last spin before the day ends. Anyways, nuff jibber jabber.

As I was going down the highway in 4th gear at about 60 mph, I cracked the throttle about 3/4 and when it got up to about 7500 to 8 k RPM, the RPM's shot up so I let off. At first I just kinda laughed cause I just thought it was the rear tire breaking loose cause they were still cold. But then I did it about 10 more times, in multiple different gear (1st - 4th) and it did it every time without fail. Obviously I know my bike, and I know that the tire wasn't breaking loose at this point.

When I got the bike home, I was looking on the left side of the bike and there was a little fluid on the metal tube/hose that runs from under the motor to (?) Looked like a tiny bit of oil.

Sorry for the lame description, any help would be greatly appreciated.

The clutch still engages and disengages just fine, and the bike is still ridable, I just cant open the throttle real hard otherwise it just revs high and wont go!!! :(

Just did a youtube search and here is a guy on a GSX-R showing what it looks/sounds like to have a clutch slip, and this is EXACTLY what mine is doing.


So how much would this cost to fix (roughly?) Do I need a whole new clutch, or do I just need clutch plates, or what?

I'm so bummed, lol.

Ok well I just talked to a knowledgeable friend and he says all I will need to do is get a clutch kit, (Plates, Steels, and springs) and that should be all. Shouldn't need a new basket or any of the real expensive stuff. Said it was most likely just normal wear and tear. So hopefully he is right, cause then it'll just be about a 200 dollar fix, not a 6 to 800 dollar fix.

Thank's for everyones help. Wait.......:crash :lol

Just ordered a new clutch kit from Brad at MRcycles. Should be here next Wednesday and I am going to attempt to do it myself for the first time. I have a service manual, and a couple of you tube videos to guide me, that SHOULD be enough.

The guys on this forum have helped me more than I ever could have imagined. I just made a thread without doing research or talking to anyone first, when I should have done it the opposite way. But once I started it......I couldn't stop. Had to keep letting everyone know I was a big boy and doing it on my own. :lol

Hey Matt! I was having this same problem after I ran my 04 R1 on the track... Just bought a new EBC SRK clutch kit, came with Springs, Friction plates and of course clutch pads. I installed everything exactly as the manual said! And guess what??!!
Went to go ride it and everything was great....at first... Then when I took it on the highway and opened her up WEEEAHHHHHHHHH!!!!! Started slipping again... same F($#%(# Sh!t!!! In every gear!!! So let me know if your still having this problem as I am... This is realy annoying and quite a headache.

Sounds like we are all in the same boat.

I got a DP clutch kit, and it said I didn't need to soak the plates. I installed it, and it did not work. So I've pulled them all out, and have them soaking for tonight.

Since the only people posting up onthis thread is the ones that need help, I'll let ya'll know if it made a difference tomorrow.

Good luck fellas

Hi guys ,
When replacing the clutch plates it is mandatory to let them soak in oil for an hour or so.
The next step, really important, check the metal plates which are interleaved whit the clutch fiber plates. If they are warped and have a blue color then they have to be replaced. Otherwise the clutch will continue to slip under heavy load. You can have new fiber plates, it won't matter.
Measure the length of the new springs that comes with the new aftermarket kit. You will find the specifications for them in the owner's manual. If they are shorter then the clutch will slip. I had this bad experience with aftermarket kits.
And the last thing...the clutch laver got to have some free play otherwise it will keep the clutch engaged just enough to make you troubles.
Other then all these...READ the owner's manual before you do any work on your motorcycle subassemblies.
There are really important steps written in there that you MUST follow exactly otherwise you will screw things up.
