Honda XR125 (CG125 Engine). Clutch isn't working anymore :(

[alol74]

Hi everyone.

Just off my bike. It broke. The clutch isn't there, it is very very light and can't feel any resistance when squeezing the clutch lever, the cable is ok, I can see that it actually turns the clutch thing on the engine itself...it just happened when I was changing gears I have managed to start it in neutral and then just started rolling it and pressed it into first gear as clutch was of no use ... Managed to get home in first gear all the way...

Anyway, can anyone suggest what that could be before I open the clutch part of that engine ?

Thanks

Not totally sure, but just to let you know in future, there is a technique that allows you to change gear without the clutch, all about revs... Look it up

might need adjusting

There should be some markers on the crank case to show where the lever should swing from and to when it works properly.

Does the lever on engine return by itself? Should do with quite alot of force

It doesn't and that is a part of the problem

Clutch springs gone, completely?

Does the lever just flop about? no resistance in either direction?

Ok. i have decided to open the crankcase cover. Got the oil out of engine.

Opened the cover. Everything seems in right place all nice and shiny.... The clutch lifter mechanism is fine, the spring is fine too... It was actually returning the lever back, but that clutch lifter spring is not that strong, so I couldn't feel any resistance from clutch lifter plate springs. Anyway, I'm wondering, if I push the lifter plate in (as clutch lifter would do), am I supposed to see clutch disks go apart ?

They might not fall apart from each other but they shouldn't be pressed together anymore, you shuold be able to seperate them with your fingers

Ok. I've put everything back as it was... Clutch lift shift looks ok and feels quite resisting again, so I guess we are back to normal... What was it ? I suspect that old clutch cable might be at fault here too - so I'm getting it replaced... Could the reason be the lack of oil as I had just 1 litre of oil in there instead of 1.1 as it says on CG125 spec ? Anyway, will be putting new oil into engine and cable replacement would be the other task for tonight...

At the very least I now know how the clutch looks like and how it works

Right. Everything is back in place, clutch cable has been replaced, new oil is in... Still not sure if 1 litre is enough ? The oil level stays between marks on dipstick though... Anyway, bike started first time (well, not quite as I had emergency button pressed). Everything looks ok, I'll take it for a test ride tonight
