Just got it firing!
Look in the V7 manual in the resource section. https://www.guzzitech.com/forums/resources/v7c-service-manual-09-12.68/ There is a section on capacities.
Thank you, sir. I did not know I could find a service manual here. That is fantastic.
Also, 170 cc doesn't seem like very much oil? but I guess there isn't much room in there.
