Just curious, what exact oil are you using? Is it motorcycle wet clutch spec'ed oil?

Nils 10/40 (thats what GasGas fills ex factory) Motul 15/50 and 15/60 (as I thought oil that is thicker when hot reduces squawking) Amsoil Dirt Bike 10/50 (designed for extra clutch feel and protection) Putoline Nanotrans GP (24 per quart, very thin, very expensive but had worst clutch feel) All of the above are motorcycle oils for use with wet clutches. |

Today I will try Motul Gear Trans 10/40 that is what a German racing team uses but I don't think it will change anything. maybe i will drill some extra holes in the pressure plate, that is what helped someone else on a KTM and is worth a try... |

Short update:
I drilled 12 holes, similar to what a guy showed me in the Dirtrider_net forum This is how I drilled the holes (5.5 mm): Pressure plate outside Pressure plate inside I decided to make some "keyholes" on the outer holes so that oil can easier get to the discs. I filled fresh oil and then warmed the bike up and started in 4th and 5th gear with lots of clutch*feathering and I really let it scream. No noises so far, but a serious test will follow next week in the woods. I also measure the throwout and its good and like it should be, when the clutch*is pulled I can see the plate lifts fine. Unfortunately the dragging problem is back. Talked to an experienced motor cycle engineer and he said the plates are sticking, probably they are a few thou too thick. He said ride the damn thing or get a new set OEM friction disks. Its definitely a problem caused by the plates... Will keep you updated. Thanks for the help guys, you are great !!! |

Dunno if you've already tried this - but if you take out the steel plates and lay them flat on a piece of glass can you wobble them? Or do they sit perfectly flat?
This should show if any of the steel plates are warped. |

Thank you! Yes, though I bought a set of new ones I checked them and they were -as I expected- perfectly straight.

For the physicians who may read here.
One of my ideas to get rid of the clutch drag my bike has when engine is hot and has been turned off for a period longer 20 seconds, was to use a longer clutch push rod or add a washer under the throwout bearing. After I had postet this in another forum one of the guys said that wont change anything and I am sure he is right. because the added length would be eaten up by the slave piston just traveling back in its cylinder for exactly the amount the rod has been lengthened. Then I read (here) that some guys used a CRF clutch and to compensate the stack height used a thinner washer between clutch basket and hub. Thinking that over I come to the conclusion that wont work with my bike either. The thinner washer would move the hub back relative to the push rod. Thats true, but only as long as the pressure plate isn't installed. As soon as I put the pressure plate on the push rod would be pushed back its normal way plus the amount of the reduced spacer. So my ordered spacers are best used as paper weights. What can I do to get more lift or in other words what can I modify so that the push rod will lift the pressure plate 0,5mm or so more? Only idea I have is getting thinner steels.... |

Severe clutch problem EC 300 2019
What about a Rekluse adjustable slave cylinder? Maybe give them a call. I’ve heard great things about their tech support.
The one problem with the adjustable slave when not using the Rekluse clutch pack is that it might not adjust back far enough as it meant to always hold the clutch disengaged when the engine stopped. Or just spring for a Rekluse auto clutch or even manual clutch (if they make a manual clutch for the GG) Sent from my iPhone using Tapatalk |

Hi,
Are you using the standard clutch lever? When the lever tip hits the grip is there more movement possible in the master cylinder to give more movement in the clutch pack? Maybe modify the shape of the lever |
