RGS Strong Coupling

Hi,
just made a test ride with my refurbished RGS engine. Coupling lever force is really high almost to strong for me for a long ride and it does not really seperate. Although I pull the lever to the handlebar the bike wants to move. Any idea?
Strong springs would be an explanation for the force but why does it not seperate. I will open the case and count the plates?

I understood you meant the clutch is very heavy and does not open completely.

Did the the clutch worked well before the refurbishment? Was the lever more sensitive earlier?

Is it shure there is no air on the fluid? If there is it will shorten the distance the piston moves. There is a bleeding nipple on lower end and the main cylinder may also need bleeding. I use a 22mm standard steel tube for bleeding. The Bayonet on the upper end may be the highest point where the air rises. If the hand lever is attached to the 22mm steel tube instead of the handlebar, it could be turned to that kind of angle the air will come out when pressing the lever. The lower end needs to be bleeded first and the upper end last.
 
Thanks,
I can check if there is air but when the force is high there should be no air. Air will soften the lever force, I think.

Piet,
You mean springs go on block length. Will check.
Force dont increase much when I pull, it's high when I start pulling. It is not that it is much higher at the end.

See you at Heftrich?

That would fit.  OE or pattern springs?  Or springs meant for something else?  Thick washers for more pre-load?

Hopefully.  I'll be there Sunday morning/midday.

I will open and have a look. Bodo made the engine, I called him today but he also has no real idea. Maybe he misses his glasses when mounting and put to much plates in??
 
Hi,
Today I opened the clutch.
What I found, all friction plates were 2.9 to 3 mm thick. Steel plates 1.5. Others I have are 2.5 to 2.8 and 1.4 mm.
Could assemble a complete set of plates with about 33 mm or 30.7 mm which I think could make a big difference.
Springs are of 2.5 mm wire and 46.5 to 47 mm long. Maybe I had others in the past with 2.4??
I will check the push rods in the main shaft tomorrow and then mount the thinner plates- hope it will work.
