yes, that would be the next move, but unfortunatelly it's a client's bike, that i've tried everything related to air/fuel (that;;s why i posted here, maybe i forgot something it's human to make mistakes) and i don't want to fix his bike anymore because acusing us we changed the spark for nothing just because he works in automobile repair shop and his mechanics did not possibly install used sparks.
he brought the bike with 3 weak spark and 1 plug no spark at all (iridium plugs) and we installed 2 sets of standard. also his plugs are carbon faulty and just got accused of this, i'll let him go somewhere else.
Funny tho, with 5 turns out, bike still idles for a while until it dies.

 

I feel sorry for the bike, LOL. Well at least it’s not yours !
