I have some concerns about the advice to add oil to the gas of outboards with the oil injection still hooked up..
I have raced Motorcycles for 35 years so am pretty familiar with jetting and 2 stroke engines...When you add excess oil to gas it will actually cause your motor to run lean. The gas will have higher SG and will not vaporize through the carbs or injectors as well. Adding oil will put more lube into the engine, but will cause a leaner condition. So the statement of richening your settings by adding oil is actually false. I know motocross bikes run at 11,000-12,000 RPMs and are a little bit more sensitive to changes in settings, but am I missing something?
I have a 97 vindicator with VRO so I have been following this pretty closely and I appreciate all the advice given...
