Mark,
Having replaced the clutch plates on my Suzuki GN125 I will be refitting the right-hand crankcase cover next. If the gasket is soaked in oil and the crankcase cover has a thin film of silicone sealant how long does it need to set before I can fill it with oil?
Thanks,
JonnyD

Jonny,

Ride it immediately. Check fasteners again after engine cools.

Mark,
I've put it all back together but I'm a little worried about filling it with oil as I think I may have done something wrong. The Haynes manual only referred to repairs to the clutch in terms of removal of the entire unit. I had disconnected the cable from the release shaft before I realised it was not necessary.
There is now no resistance in the release shaft- it does not spring back into place when you release the clutch lever. I've checked the free play in the cable, but I don't think that's the issue as moving the lever back and forth results in the release shaft moving as it should.
I sheared a bolt putting the crankcase cover back on first time and had to get another gasket. Please tell me I don't have to take it apart again, I'm more than happy to learn from my mistakes but this is getting a bit much!
Thanks,
JonnyD.

Jonny,

You'll have to figure out correct alignment of clutch linkage. You may need to pre-load linkage (compress return spring).

What year is the GN? I'll peek at the microfiche.

Haynes manuals seem to lack information.

Mark,
It's a 1998 GN125/E. Someone doing work on it previously suggested it may be an import due to odd sizes of certain fittings.
Anyway, the lack of resistance in the clutch was due to me being stupid. The release shaft has a certain amount of rotational free play before it even starts to move the clutch. I hadn't rotated the shaft to the point where it encounters resistance from the clutch springs before attaching the cable. Hope that's easy enough to understand!
However, even though there is now resistance in the release shaft and the lever returns to the correct position when released, the clutch is not engaging/disengaging within the range of movement of the lever. I'm going to have a fiddle with the play in the cable again, and maybe reseat the cable fitting on the release shaft in a different position.
I've learnt recently that using silicone sealant on the crankcase gasket may not have been such a good idea- any comments?
Is there anywhere on the internet that supplies copies of the microfiche you mentioned?
Thanks,
JonnyD
