New Problems with Transmission/Clutch

[SuzukiGS]

So right now my clutch I think is slipping. What it's doing is that when I go and shift up on the bike, and then lay into the trottle it will rev up to about 6 to 8 thousand RPM's and then engage and then will start moving again. And it doesn't do it all the time and if I just slowly roll into the throtle it won't do it. Only when I hammer it. I think It may be my clutch is worn but I have no idea and it doesn't do it in the lower gears it seems like. Also, another thing is that it won't go into neutral unless the engine is off. So is my clutch worn, transmission shoty or what?

First thing to check is to make sure there is a little slack in your clutch cable adjustment.

If that is OK, you likely need a new set of clutch springs. About $20 for a set of stock springs (no need for heavy-duty or high-performance) and maybe another $10 for a gasket and you will be good to go.

Where can I get springs? And how hard is it to replace them? And whats the difference between Heavy duty and stock? Why aren't the HD one's worth it?

this is where I would get it, since they are close by,

Its pretty easy...

Hopefully you wont have any stuck or stripped screws in your clutch cover.

Thanks guys. This bites, I just put brand new Oil in it mabe 20 miles ago. I guess I'll have to go buy more though. Oh well. Thanks for the tips.

Just a question about the basic functionality of the clutch, how does it work? Why does the springs allow slip and how does it work with the clutch being wet and having 8 plates?

NOT. Do it on the side stand. No need to drain the oil.

[SuzukiGS]

Ah, thanks, I didn't even think about that.

BE CAREFULL of the 10mm screws They can be streached and break when retorqued

Most slipping clutches grab until 6000 and then slip.
They don't grab at 6000.

The clutch works because the springs are pushing all the plates together. If the springs are weak, they won't push the plates together as well, and they will slip under power. Keep in mind that the plates are "wet" with engine oil and you can appreciate just why it's necessary to have good springs in there.

Bike Bandit is OK for buying your parts, but just about everyone else (except Alpha Sports) is cheaper.

Slip?

Was it slipping before you put the new oil? If not, maybe the oil has some kind of additives?

Second that on the oil type. Make sure the oil you are using is approved for wet clutch applications. I do not remember the spec but you can't go wrong buying a name brand oil intended for wet clutch motorcycle use.
