This morning I took off my clutch cable, to fit some new cable adjusters to the lever (I had some chopped BMX ones on it) I removed the lever and disconnected from the the lever housing, screwed on the new adjusters and fitted it all back together. The lever was very tight now, so added a little adjustment at the the engine end to slacken off a bit.

So now the clutch doesn't engage at all, I can knock into gear but when the levers released, the bike wont move. I've tried various adjustments to the cable at both ends, but no change.

I wonder if I've put too much pressure on the plates while refitting the cable. As I left the cable attached at the release mechanism, would the extra tension crush the friction plates,
Any ideas? I guess this weekend I'll be rebuilding a clutch then Laughing

I haven't taken it apart yet, but may as well do a complete over haul while its apart.
Order so far, missed anything? I've never done a clutch so any info and advise will be a great help Wink

i would imagine its a very similar setup as the CG

i replaced my clutch last week, an have noticed weird goings on with the cable too

on the case its on the largest adjustment, the same at the lever?

i also found the bike was slipping really bad not long after i had refit everything, turned out the bolts holding the springs in had loosened off Laughing

If I read this right it went (chronologically):

1) Clutch working.
2) Mess with cable.
3) Clutch not working.

As such, you haven't got it reassembled properly because nothing you could have done to the cable would damage the clutch itself.

I'd be looking at the clutch release lever on the RHS crankcase cover as my first port of call. I wonder if you've managed to flip it round/get it jammed or similar.

The release mechanism wasn't touched, i took the lever off the handle bar, to give me enough slack to remove the cable, leaving the mechanism end as it was. Screwed on new adjuster put the lever back together. Pull the lever the mechanism moves freely up and down, but no release on the clutch. Question

Just dive right in there and replace the entire clutch without checking the release mechanism.

No skin off my nose.

Remember, if the clutch isn't gripping, the plates are being held apart by something.

Not saying that i would go and replace the lot without checking, just i didn't touch that end at all, so question whether it would be that? Wink

The new adjuster is bigger, it had push bike adjusters just about holding the cable in, the adjusters I've replaced with have an adjustment nut, so i would assume it'll gave less cable at the crankcase end? as the nut took up the slack it used to have.

I doubt that there is any connection with messing with it and then it not working, why would there be it is just not logical. buy a new clutch and replace your old one, people like Mr Stinky seem to get their rocks off by giving out stupid advice .

The cable is too tight and the clutch is not engaging, release one end of the cable and see if clutch engages(wouldnt try starting it) but you can rock it in gear etc...You will also see how much the lever moves at the engine point to confirm too tight etc...

That makes perfect sense to me Thumbs Up I'll be re placing the cable, as the old one is starting to fray so could be binding. I will check it out then Wink

Not that I know anything, but doesn't doing anything to the clutch cable release the tension on the clutch arm.

You need to get the tension back on the arm before adjusting at the bar... unless you've got bloody good adjusters

Panic over, I removed the cable and rocked bike back and forth in gear, and the gears engaged. Was just a case of re fitting the cable and finding the correct tension on the adjusters Thumbs Up
