Clutch overheated
 

so I did a charity ride out yesturday which involved so very heavy clutch work as there was some many people I never had a clutch overheat before so excuse the nood side here lol

So when it "overheated" I slowly lost the ability to use the clutch almost felt like the cable had snapped ?

What if anything should i check ?

its only after a service only 450 miles on the trip

And is there anywhere of preventing it again ?

Cheers

Any chance the service technician put the incorrect oil in? Standard oil without the friction modifyers for the clutch can and will cause slip. I know its a contentious issue with some but thats what the additives for wet bike clutch oil is for.

Fortunately for me, no..I havent had it happen but I have always used bike specific oil.
Im sure others will provide more advice and experience.

Hey it depends, if you were riding at a snails pace for ages so constantly pulling in the clutch then this could be normal and when the engine cools off the clutch returns to normal????

It is not unheard of for this to happen with cable operated wet clutches.

It is usually due to the whole clutch pack expanding due to extreme heat build up, which causes the free play to gradually disappear as the expansion takes place. This in turn causes the clutch plates to begin disengaging and clutch slip to start. Eventually the slip will get worse until the clutch becomes fully disengaged.

Making sure the clutch has the correct free play is the main preventative measure, but making sure the oil is good and of the correct spec is also important.

If these symptoms ever happen (usually in stop-start riding on a hot day), then stop the bike and let it cool down. Nine times out of ten there will be no lasting clutch damage done. If you soldier on with the clutch pack overheated, expanding and slipping you will eventually fry the clutch plates. Dialling in more free play can help get you limp home gingerly, but won't fix it.

Sounds strange. Ive never had a problem ive climbed a VERY steep hill that was 3 miles long behind a truck doing 5 mph all the way up so i had to ridr the clutch but i did wounder if it would if it would overheat

Might also depend upon the weather and the ambient temperature when the event took place, if it was raining and cool for instance then the heat would dissipate more easily, if instead it was a warm day then the heat had nowhere to go so the clutch and engine got very warm so the situation gets quickly out of hand.....

sounds like it did overheat it was one of them runs that you couldnt get a gd speed up to help the cooling it was a pretty warm day <for winter> and the fact that 400 odd bikes trying to get through a busy town centre did help

After a couple of stops it return and has been ok so far lol

Cheers guys
