HELP! Clutch not disengaging! CB400F

<< < (2/2)

Alright guys,

Thanks for the replys.

So dropped the oil and took cover off last night. I carfully and lightly used a flat bladed screwdriver to seperate plates whilst dripping engine oil in between plates. After I put cover back on and filled up with oil again, I rocked backwards and forwards whilst in gear with clutch held in and the rear wheel now moves freely ! :) Seems like it was just sticky plates!

I dared to start her in gear and clutch seems to be working as it should now, however there is a little clutch drag, I think it just needs running in as its been dry stood for so long.

I also checked the kick starter mechanism and it all looks fine to me... however it just doesnt seem to want to bite if I move the kickstart slowly. Am I just not "kicking" fast engough for it to bite? Video:

I did check the ratchet mechinism and it moves freely.

Cheers,

The splines on that kick start shaft look pretty bad. Are you sure it's not just spinning on the lever? Watch the centre shaft as you slowly kick and see if it's actually moving.

Make sure the springs are located properly as well or it won't work.

At least progress with the clutch, so half way there.

The kickstart, the loop's spring tab at top left in photo should be held stationary when installed as it's this that when you rotate the shaft will cause the engagement spiral (inside that gear) to push the two sets of teeth onto each other and then drive the gear that turns the engine.  Phew, that's a long sentence  :)

If that "tang" also rotates, then nothing happens. Held like that (out of the engine) if you rotate that tang it should show you the paired gear teeth come into engagement if you do that while holding the rest of that assembly static.

*Update*

So tried the kickstart tonight and it's working perfectly!

The only thing I can think I might have done is not put the kickstart hairpin into the slot when fitting the mechanism into the engine. Not 100% sure this was the cause but it's the only thing I can think that I might have done.

All working now :)

Just got to figure a way to stop my clip ons from slipping on stanchions! But I have a different post for that  ;D

Cheers all

If you can find a decent second hand one I'd advise changing the shaft as the splines will go eventually. The inner ring is almost useless as they are, that means the outer ring is carrying all the stress and they will fail in time. Either that or don't use it very often  :)
