Hello,

I have tried to find a specification for the axial clearance/play for the rocker, but can't find any information about this in workshop manual etc.

Anyone having an idea of what the clearance/play shall be?

 
Indeed not specified.
Take a look at this thread: http://www.laverdaforum.com/forum/index.php?action=search2
page 2, on top sfcpiet's posting
found this by search function: "rocker sideplay"

Good luck,
Ernesto
 
Thanks!
I read the thread "hard ticking at 3500 rpm" and the suggestion by Piet. In that case the play was around 0.25 mm, but my fear is that it becomes to tight. (One my BMW R1200C min clearance is specified to 0.05 mm, but they are of cause of an completely different design)

Anyone with advice of what the minimum play shall be?

Not really, actually quite similar in regard to rocker geometry. 

Normally, the axles can be shoved right in against the rockers, and the rockers tapped lightly to achieve a little space.  Reckon 0.1mm would be more than ample.  I have found heads in which the axle bore was not deep enough, the rockers needed to be shimmed to close up the play.

To set up heads nicely i grind the shoulder down on the rocker spindle until sideplay is reduced to 'a minimum' (need an accurate grinding devce like a valve grinding machine to do it cleanly) ... Piet's 0.1mm sounds good to me.
