GT550 oil pump set up.

Hi Guys,
just a quick question on the oil pump - throttle settings.

Do the two lines on the pump arm align when the throttle is open and the dot is in the top of the window on the carb - or when the throttle is closed?

- the haynes manual and the climar manual are a bit vague on this (or maybe im overthinking it!!)

Regards

Steve

Yes, according to the 550 shop manual at oldjapanesebikes.com
