delusionised,
With that mix you lean out mainjet very much,be carefully.
It?s about how fast air travel through engine:
small bore(125cc), high rpm(10.000 and above),high airspeed,less time to attached to cylinderwall,need more oil.
3%-4%
Big bore (500cc), more air, but low speed,low rpm(up to 8000),need less oil.
2,5%-3%
