Low oil causing a wet clutch to slip!?

Hey guys, I've been trying to figure out why my bike will travel up to about 12k rpm's no problem but once it hits 12k, it just revs straight to redline. It feels as the clutch is slipping but I've put it into a high gear at a very low speed and opened the throttle and I got no slippage. So I am checking everything over for the maintenece I'll be doing this coming weekend, and I notice my oil it pretty low (not good). Does anyone think this can cause the wet clutch to actually slip at high rpm's due to the engine needing more oil then at a normal cruising engine speed?
If no-one knows, I guess well find out when i do my oil change!

Mike

is your clutch adjusted right? thats probably what it is. most newer riders for some reason seem to like there clutch to disengage at the very end of the lever when they let the clutch out. i dont know why it is bad on the bike and teaches bad habits. probably is slipping but the motor doesnt have enough power to slip it anywhere but near redline and near peak horsepower. keep doing it and eventually it will slip everywhere.

Nope, clutch engages at just under halfway out. Everythings on check with that.

This is an early stage of slippage. If you wait til it slips at 2K rpm then that is too late and might damage other hard parts that could cost you more money.

I had something similar happen and took it to the stealership and they said the clutches needed to be soaked because they were drying out or something like that. Whatever they did it worked though

That's for new clutch fibers, it shouldn't affect existing clutch fibers because they're always bathed in oil.

Chances are your clutch is getting worn hence the slipping. Sometimes, changing the oil can have an affect on it's performance as it wears, and may improve keeping it engaged with new oil.

My actual first thought was perhaps your clutch springs need to be replaced, but I think Level5 is probably spot-on with the early signs of clutch wear being the culprit.

Sorry forgot about the miles, kinda crucial. It's got 13,000 miles on it and it's the original clutch.. I should probably just get it replaced then huh? BUT I don't want to pay a stearlership.

If I'm going to get it replaced I don't want to do an oil change and then have to drain the new oil I just put in out.. So would it be ok If i added a bit for another week or so until I get it changed?

Are you using a motorcycle oil? It does make a difference.


And yes, sounds like the clutches are wearing down/slipping during higher torque requests.

You should keep your oil level full no matter what you're doing.

Thats what i thought too but when i asked them about it they just kinda blew me off and said they need to be re-soaked. Then when i picked the bike up my transmission was broke. Somehow it was broke when i dropped it off even though i rode it up there. I hate the stealership

Without knowing the exact whole story, I'd say you got taken unfortunately.

Just like the old Maaco commercials used to say, "Uh oh, shoulda got Motorcycles Unlimited"...

Oh no.... they screwed themselves on this one. When i said I started it and it made some horrible grinding noise they told me it was fine when they test rode it. They take it back and pull the motor apart and find one broke and two bent shift forks and some other stuff. Ask if i want them to fix it and I say well yeah you broke it. Tell me its gonna be almost 3 grand. I tell them sorry bout there bad luck but i'm not payin cause they did it. Then he says how could we have done it we never test rode it. This is when I went off and it took a few weeks of arguing but got it fixed for free
