Dragging Clutch

Featured Replies

I have a '01 rev-3 250. I can't seem to keep the clutch from dragging.

I know I have bled it properly, and have adjusted the throw on the lever asymbly. When I pull the clutch in I can fell when it actually starts to disengage the plates, (about two thirds into the pull). What gives?

Change the Gearbox oil. This would be the main cause of clutch drag.

There maybe a build-up of muck on the plates that will stick them together. You can also take the plates out and clean them in a solvent like petrol, allow to dry then reassemble.

:o WOW

Hold on here....... Never let your clutch plates soak in any liquid outside the clutch basket. The clutch plates will expand and swell like crazy and they will never work correctly again.

They will basically swell and become thicker, when you pull in the clutch the plates will be thicker and not let the space develop to afford clutch release. :D

Being a 2000 it might be time for a new clutch!

I would imagine PA means clean the plates with Petrol, NOT soak them in the stuff Billy T :D

'and clean them in a solvent like petrol, allow to dry then reassemble."

You could be correct and I hope you are, but with a statement like the above using words like clean "them IN and let dry" lead me to beleive that they were going to be submerged in a lquid and the taken out and let air dry.

Maybe it was being to overley concerned but I have heard of people soaking their clutch packs in cleaning solvents only to find out that they have swollen beyond recognition as the cork like material soaks up the liquid.

The same goes for anyone pulling in the clutch lever and using a rubber band to hold it in overnight. This was done by a rider who thought he could solve the problem of cold dragging clutch in the morning by holding in the clutch all night.

What he did was allow the clutch pack to soak up the clutch fluid and the plates swelled. His clutch pack had to be replaced shortly after.

Better safe than sorry.

Dont know if this is related but Ive been suffering from clutch drag on my 250 techno. Fed up with this and following up a suggestion I zip tied my clutch lever "on" overnight. Anyway clutch really bad a few laps in and when I got home and drained the oil (only done one trial) the oil was a dirty brown colour with a clearer fluid on top. Also discovered main bearings were shot. Coincidental?
