thank you all for your supporting comments !
engine has now about 250miles and some extra idling/revving hours...
after a week or so I will change oil to check if there are any metal residues or anything suspicious, check valve clearance, spark plug color etc and IF everything ok, then dyno is next...
so far AFR is set for 0-60% throttle and up to 8500rpm or so...
engine sounds more familiar, less noisy and vibrating than the video but feels waaaayyyy different !
I get more and more astonished by the performance of that thing...
can't wait to twist that throttle...
