New finds after testing:
when i use original air filter and snorkel, my Ten goes beautifully smooth, that's great, almost no surging - (I must to focus on it to feel it), but engine is not so playful, rather lazy ☹

when i use DNA Stage 1+2, bike goes better, accelerates faster, engine is more flexible, but Ten starts surging from 2,500 to 4,000 rpm, (not as strong as before, but still feel enough) ☹
Fuel mod set from 3 to 8, best setting according to spark plug color = 6

Anyone have any idea why DNA Stage 1 + 2 Ten starts surging?
