Did you fix the problem with the PV and does it run good again? Last few rides I have noticed the same symptom on my ec200-13. It lacks bottom end power and I need to slip the clutch a lot to pick up rpm, then it runs OK. No play in PV linkage and it closes as it should.
Been fiddling with jetting also but this feels like something else. Currently running:
Pj - 40
Mj - 180
Needle - CCL in middle position
Pilot screw - 1,25 turns out
Hope I can fix this soon
