Where did you get the info about the pump pressure. How much adjustment was required to get it down to 1.2 bar. Seems strange that YS don't set this pressure correctly prior to shipping their engines.

Friend of mine who is fond of mecanical (he was a Renault Alpine competition mechanic) did differents tests on stand (same as shown by Scott).
To decrease pressure I turn counterclochwise the regulator screw.
At iddle when pressure is 1.2 bar ; at max rpm pressure is about 1,8/1,9 bar.
Knowledges has been shared. So in France those who have CDI (170 to 200) proceed in this way.
When there was issue it is very easy to do and know if pump is correct or no.
