No clutch in warm weather

[cammy5477]

Hi guys
I lost all clutch yesterday when riding at speed in nice weather....I've since had my clutch fluid changed which has solved the issue temporary but I'm thinking of just changing the master and slave cylinders. Where is the best place to get these? Bike is 09 GSA

I managed to get a master off eBay recently , a low mileage one for £45

Check the routing of your clutch hose, ensure it is away from the engine/gearbox. There was a recall for it years ago, your bike may have been missed.

Probably just absorbed moisture boiling off in the hose.

If changing the fluid cured it, may I ask why you want to change the cylinders?
Genuine question (I have an 09 GSA too but havn't noticed any clutch issues yet).
Pukmeister - I'm not aware of this recall. What was the problem / fix?

The clutch fluid level at the mater cylinder rises as the cutch wears. Add some summer heat casing fluid to expand and you have the clutch being held open by hydraulic pressure. Changing the fluid has dropped the level to normal and all is well again.

The simple test if to extract some fluid from the reservoir with a syringe and see if the clutch slippage problem goes away.

If air is being drawn In even very slowly I don't want to have a trip spoilt having no clutch I'd rather sort it now and have confidence in the bike again.

As you wish but I reckon Bendy nailed it.

I was in the Dolomites a few years ago with a lad who's GS lost its clutch in similar circumstances. That turned out to be the fluid. I would say a change of clutch fluid is worth the effort before you go to the time/expense of cylinders.

Thanks for the advice guys I think Ill see how it goes before buying expensive cylinders

The same thing happened to Diplomatic Danny in the South of France last summer, rectified by flushing/bleeding the clutch with Citroen LHM+ fluid in a supermarket car park on a Sunday morning.

The slave piston spins when the clutch is pulled. Flushing out old oil is nice, but just cracking open the bleed nipple to drop the reservoir fluid level will restore the clutch control.
