Clutch Problems CBR 600f (sorry i know its not a BMW)

[high_tower]

Morning all,

I know that it is not a BMW but a friend of mine was out on her 2001 cbr 600f yesterday when the clutch stopped functioning.

the cables intact all the way down to the tiller arm on top of the clutch housing. it's really really light now and doesn't feel like it's actually pulling anything. the only real springing back is from the little spring located on the tiller arm. does anyone have any experience that i could use to get her back on the road?

Hi mate.
Could be that the cable has snapped inside the housing. 'Fraid it'll need the cover removing so you can see what the problem is.

so from the cable off the clutch lever that comes down the the top of the clutch housing and pulls the little tiller arm fine. i've checked to make sure that actually turns the rod going into the housing.

so that rod connects to the clutch via a cable? or am i just a bit lost.

sorry if i seem a bit clueless never touched a clutch before on a bike

I stripped down my old Thunderace clutch a while back. If i remember right there is a pull rod on the inside of the housing that engages and disengages the clutch mech. It sounds like the fault might be in this area, but i couldn't be 100%, as iv'e never stripped a CBR one down, but i should imagine that most non slipper clutches are similar.
Hope this is of some use.

i guess i'm going to have to investigate. thanks for the help guys

any words of wisdom before i do something stupid and break more?

Sounds like the clutch springs have failed or the actuation arm has broken inside the clutch cover or maybe the actuation bearing has failed/colapsed. The only way to find out is to pull the clutch cover off. A simple job; drain engine oil and undo the cover bolts.
Let us know how you get on.

For a start have a look at this manual. It's off the later RR but since that's based on the F motor (at this age) you'll be somewhere near.

I take it you can see the clutch actuating arm moving when you pull the clutch lever in?

In which case, chances are it is either the clutch pullrod has snapped the 'top hat' end or the clutch lifter has snapped where it contacts the pullrod. Similar thing happened to a colleague with a 600 Thundercat and it took chunks out of the clutch basket too.

If it's a multi-spring clutch rather than a diaphragm clutch it is unlikely to be the springs.

With the bike on the sidestand there is a good chance that you can pop the clutch cover off without draining the oil. I certainly could on the 1200 Bandit. Have a look at how deep the sump is for guidance.
