Forexample, JS7 on a 125 needs more oil that your granddad riding the same bike around the back yard. Outdoors pros need more oil than the same guy racing a SX. Also if the oil is for both Premix AND Injection, run the next richer step 40:1 go to say 36 or 32:1. Injection oil is pre-diluted and a tad thinner than an oil only for premix.

Just undo the one near the gear lever, lean bike around a bit to get it all out, then replace plug and put 600ml of oil in, no more. The plugs on the right side are prone to stripping threads out the case.
