I've been helping BigTito work on this, and nothing is adding up. We did find that the throttle cable (the adjustment by the handlebars) was a little bit out of adjustment, which had the oil pump lever a little to the leaner side and was keeping the throttle bodies from opening immediately with the throttle, which would put to much oil to the engine to soon but that extra slack had the oil lever leaner which would help put less oil to the engine at full throttle. Anyway adjusted the cable which brought the slack out of the throttle and the oil pump lever pointer back in line with the scribed mark. Thing is still burning a ton of oil.
Wondering if its possible that something inside the oil pump can stick? I know for sure that the oil pump lever itself is not sticking. But something is allowing way to much oil into the engine, and all the oil has to go through that pump.
