Slippy clutch

[Delboy777]

Ok its probably been covered elsewhere but i cant find anything like the the symptoms im getting. Bought my TC with 22k on it and i have done 2k since then. Acouple of weeks ago i had occasion to pin the throttle in 6th whilst doing an overtake and the clutch started slipping It feels fine in all other gears and having read some posts i know its more likely to do this in the higher gears because of the load on the clutch being less in lower gears. The clutch lever feels fine and works as would be expected at around half way out when pulling away etc. But if i just pull the clutch lever in a couple of mm whilst riding the clutch starts slipping Do you think its fooked and requires replacement or could it something else that would cause this ? Reservoir is not too full so i can discount that i think. cheers, Del

Have you a little free play on the clutch lever before it "takes up"

I had a guy here last year bike just outta service blah blah blah

6000 miles Slipping clutch

The Cure Adjust free play in clutch lever Job Done !

Handguard fouling can also be a problem it just doesn't let the lever fully out

I changed the levers when i got the bike and fitted short ones so fouling isnt a problem. However i will take a look at the free play. Cheers,

Just checked and the clutch operates at around half way out from the bar and when pulled in does the exact same, seems to be plenty free play before it "takes up". Would it make a difference when the bike is hot ? No signs of oil seepage from the rear seal at least i cant see any.

Quite possibly Maybe check the level in your master cylinder is it very high ???

Take a table spoon out and leave room for expansion it takes very very little extra to create a bit of pressure in the system and make it slip as illustated by the handguards issue

Take starter motor off and check for Oil contamination

I think you can see the plate thickness too check it I think 6.0mm is the minimum allowance

The level seems fine in the reservoir, thats one of the first things i checked following previous posts on here. Need to get spannering and have a look.

Go on a diet, that could sort it....

 

[fringe]

Try replacing the original lever and see if it still does it, shouldn't take long too test.

And you can go and suck my red ringpiece till its white, you fuckwit.Nobody asked for your ignorant comments.....................now go and do something usefull for the rest of humanity................like drop dead. asshole

Red ringpiece? I'd go see a doctor about that, good luck locating it under your great big fat arse. credit to you thou it's a unusual request from one man to another. Top tip to stop the redness, stop sticking things up it........

you guys crack me up,i just love it when the banter flows

What you are dercribing is exactly what I would expect to happen with a clutch that was on the way out! It may only just be a bit of oil on the plate or glazing but the higher the gear with a greater load in the top power/torque rev range the more likely your clutch will slip if its dodgey. If you nail it in top from say 4k on a straight bit of road if the clutch is in any way suspect I would expect it to rev right out as soon as the needle hits 6k.

Excessive revs and clutch feathering will duff the friction material it in a few thousand miles.

 

[Delboy777]

Since im never guilty of doing much in the way of feathering the clutch and the fact that ive only done 2k since i got the bike i think im going to go back to the dealer and see what they will do regarding replacement. Id be very hacked off if there was no sort of contribution towards its replacement from them.

Take it back - chances are the previous bloke was a clutch wrecker or there could be an oil leak.

Im leaving for the TT tomorrow Bendy, so i will speak to the dealer when i come back. It will only do it if i pin the throttle in 6th so i will avoid doing that while im away. I have the benefit of the extended warranty should it break down. Hope i dont need to use it while im away

Interesting thread. Last June, my GSA had a new clutch fitted under warranty because one of the techs noticed the clutch "starting to slip" while road-testing for an unrelated problem. Mileage was about 12k at the time.

A couple of weeks ago (with another 8k miles on the clock), towards the end of a longish ride (400 miles), while giving it beans to accelerate from a slip road onto a dual carriageway, I detected what I thought was clutch slip. I wasn't sure, so once I had a clear road I tried it again. Definitely slipping a little bit when accelerating at peak torque in a high-ish gear. I continued for another 100 miles at a reduced pace (didn't want to break down far from home) without further incident, then tried it again once I was nearly home. Still slipping a bit.

For clarity, the symptoms I saw were that when accelerating with WOT in 4th/5th with around 6k-8k rpm showing, the revs would rise a bit quicker then road speed, then remain more-or-less static until road speed caught up with engine speed.

Phoned the dealer and booked it in. Took it in last weekend (didn't ride it at all in the meantime). They were unable to detect any clutch slip on two test rides, and they also dropped the starter motor and had a look at the clutch using a mirror and a camera arrangement. No signs of wear, heat discoloration etc found, and no signs of any oil leaks. Bike returned to me "No Fault Found".

So I'll just keep an eye on it and see what happens on the next extended ride.

Make sure the clutch fluid level has not got too high and the lever is not snagging on the hand guard.

"around 6k-8k rpm showing"

shoorley there's shom mishtkate Moneypenny the bike rev's out at 8.5k. Don't you mean the needle whipped round from 6-8k? because that is what would happen. You ain't going to notice clutch slip at 8k it will start 5.5-6k and spin up!

 

[Roymondo]

TBH, I wasn't really studying the rev counter that closely. The point at which the slipping manifested itself was probably around 6k rpm, but by the time my wetware had registered what was happening it was rapidly approaching 8k (at full throttle in 4th gear it only takes a second or so to move between the two - even with no slip). My bad - Sorry.

But it's a moot point anyway - Dealer had the bike for a couple of days and road tested it without finding any clutch slip. They also dropped the starter motor and had a look at the clutch in situ using some sort of endoscope arrangement. No signs of wear or blueing of any parts, apparently. So I've got the bike back with "No Fault Found". I'll wait and see what happens next time I take it for a day's riding.
