Hi, Any help on this ongoing saga is much appreciated.
09 FE 450, when its cold the clutch works perfectly, the lever is nice & normal feeling.
The warmer it gets, the pressure/friction/engage point of the clutch moves in closer to the bars, leaving excess floppy lever movement, until the friction point is rite at the bar or beyond it, there is no clutch at all, the lever is completely floppy. To get to this stage it can take up to 15 to 20 mins of off-road riding.
Most of the time there's a tiny bit of clutch pressure rite at the bars when the lever is pulled in hard. But if I ride a bit more I'll have no clutch at all.
If I stop & turn the bike off, pump the lever the clutch comes back to normal. But when I start riding again within 7 seconds it's back to virtually no clutch.
The clutch is not Slipping.
I have already just replaced the Master Cylinder Piston & the Slave cylinder piston thinking it seems like a Hydraulic problem. But replacing these 2 has not affected it. + I have ensured there is no air in the line bleeding from the slave cylinder with a syringe.
Next step is to pull the clutch apart & have a look at it? See if I can see anything wrong.
Thought's?
Thanks.
