YAMAHA's oil injection is about as good as it gets, but your HPDI MUST have oil injection to get ANY oil to the bearings. The HPDI injects the fuel directly into the combustion chamber, so no fuel passes through the engine. If no fuel goes through, than no oil would get to it with premixing. OPTI's, HPDI's, FICHT's, ETEC's, and any other direct injected 2 stroke engine MUST have oil injection to get oil.
