Ok,

After a mere 19yrs, the Dyna S system (for a Kwak 900) I fitted to my SF is dying - no problem, stick the points plate back on and deal with it this winter later.

BUT - which set of points is for which cylinder?  I can figure this out...but thought Id save some time and ask. Been awhile since I fiddled with Laverda points...
 
Too bloody easy. Had a mate with a 650 Yam who couldn?t start it after a points service and pushed his bike to the local car garage in desperation, "The cam timing is way out, mate, it?ll have to come apart to fix". He was waiting for a truck to take it to a bike shop for the repair when I dropped by and showed him.
 
Hi,

Remove spark plugs but plug them both into the plug leads and lay them on the engine so they earth.

Turn on the ignition and open one of the points manually. See which plug sparks and then you will know which plug ties up with that set of points.

Regards
Mike
 
Depending on how the cam and crank were positioned relative to each other when cam chain was hooked up either set of points can fire either cylinder so you need to work it out, find which cylinder is on compression stroke as it comes to TDC and then ensure that cylinder is fired by the points which are just about to open. You can change sides by swapping HT leads or connections to points or connections to coils :D
