Has anyone tried putting the oil from the oil injection pump into a "t" in the gas line before the carb, instead of using the nipple on the intake port? Would probably need to jet up one size but it would give you a better oil distribution.
I've seen this on other 2-stoke motors. I'm getting ready to change the intake manifold on my bike to a larger one that doesn't provide an input for the oil. I can put in a new oil port on the manifold, but t-ing into the fuel line would be easier.
