Clutch whine/slip. - SV650.org

20-07-09, 08:29 AM

Well I changed the chain and sprockets over the weekend and got Helga through another MOT. Surprised me I tell you, not even any advisories.
But I digress, I thought the chain and sprockets change had resolved the clutch slip that I was getting, but no. On the way back from the MOT it came back. Slips only in first gear, and when it does there is a touch of whine to it. A loud-ish 'eeeeeeeeeh' noise, and then sometimes like my journey this morning it was fine.
So can anyone advise what could be causing the slip and whine and where I should be looking.

Is it properly adjusted at the clutch actuator Grinch?

Well I think so, as when I changed the chain and sprockets, I also took it off, greased it, lubed the cable and then re-adjusted it all. Either that or my adjustment made it worse.

might be worth removing the clutch cover and having a good look at the springs/plates. You'll need a new gasket handy for refitting though. If you tilt the bike to the left on its sidestand you should be able to do it without dropping the oil.

Might be worn plates, tired springs or even a loose spring fastener. Assuming its the clutch at fault.

I hope not, I only just swapped all that.

Is the noise when you let the clutch out? If so mine does that occasionaly and a top up of oil usualy cures it. However i do think my clutch is on its way out and has been for a while to be honest.

Yep, as I pull away. I know that these bikes can get a bit of clutch whine and slip, though this seems excessive to me.

what kind of oil are you using?

Once you're moving, do you get any clutch slip by loading the engine hard in 1st / 2nd / 3rd without touching the clutch lever, or is this only when pulling away?

Only ever pulling away, so far all the other gears have been fine.

I'm currently running Halfords oil, semi-sith.
