I guess I have been the odd man out on the Scura clutch situation. Although I have sold my Scura, I remember this internet frenzy about the clutch.
I loved the stock clutch and aluminum flywheel. It was the best-performing Guzzi clutch that I'd ever used. Pull is so light and take-up is so clean. The motor revs quickly and with spunk. I loved it.
I was never convinced that the clutch problems talked about were as widespread as many people believed. Yeah, some pics from europe of an exploded flywheel and holes in the engine cases are striking. However, I asked a prominent tech guy and dealer if there was ever any problems with the venerated twin-plate clutch. "Not very often" he replied but occasionally something did happen even to those he said.
So, my speculation was that the incidents of single plate failures may be within some typical rate of incidents, much in the same way as with the twin-plate clutch. I just never believed that ALL single plate Guzzi clutches would grenade. I have known of a good number of them that did not.
I dunno. I think if I was having trouble with my single plate Guzzi clutch, Id remove it and look things over. I'd be sure to check the bolts on the flywheel and maybe try to add some washers to the heads if they werent there. If I didn't see anything amiss, I'd bolt it all up and try again.
