If the thermostat is working properly you should be able to keep a hand on the radiator for a couple of minutes after starting and have it stay basically stone cold then suddenly get too hot to touch.
I'll try that, thanks Have only been touching the hose to the Wax Unit so far. Cold for a long time and hot all of sudden, and then the Wax Unit activates.
As you may know the other three SVs get synchronised to the reference SV so that the vacuum in the intakes is balanced when the engine is warmed up ...
Vaguely remember, Synched my 03 20 years ago. I need to synch this 2012, it is kind of a sleeper compared to the old 03 and maybe the synching will help.
The "sleeping" may also come from the PO riding with his wife in "sleeper" mode, it may just be in need of a good Italian tune up (and Mystery Oil).
..... You should only be able to move the linkage to open the valves further as the wax unit nut would stop you closing the valves, unless the wax unit is already in the hot position. When the wax unit is hot (the shaft has extended) then you can easily move the starter valves to open them further.
Excuse my nonsense: It is in fact moving the linkage to open the ports as you say (like pushing the choke back).
There is a video on the VFRs starter valves that I found pretty useful.
Very useful. Thanks!
