Oil pumps, besides variable and non-variable, any other differences?
I know there are non-variable oil pumps (like on my '94 750) and there are the throttle-connected variable oil pumps (like on my '96 780) which inject less oil at light throttle and max oil at full throttle. Besides that, are there any other oil pump differences?
But do all pumps pump the same amount of oil at max? Does a 780 oil pump pump more oil (at max) than a 650 oil pump?
I have a few spare 780 variable oil pumps with throttle linkages and I'm considering putting one on my 750 to reduce light throttle smoking and oil consumption. I would have to fab up a throttle linkage for it.
My other question about oil pumps... is it better to inject the oil into the intake manifold (like my 750) or into the carbs (like my 780)?
I'm guessing carbs since they started doing that later... must have thought it better.
Can you take a carb oil injected engine and convert it to manifold oil injected (different intake manifold with ports)?

Not sure if there is a difference in pump rates, but there is a little history.....
