Jet size for Gilera Runner VXR 180


New Member
Hi anyone know what jet size I need for a VXR 180 in a walbro carb? I have currently a 34 and 108 with standard airbox and GPR exhaust.
I am getting some bogging after 30mph and not sure if it’s this rubbish fuel ⛽️ or my jets that need changing.
the bike was ok before with the 108 jet so not sure what’s happend.
