Update: After taking out again the carbs for diaphargms replacement as prevention, and still no choke more tant 2-5 seconds ( even no choke lately) last mid and hot days saw that at cold morning was not so bad once engine was normal temperature but the more the outside temp raised, the more the throttle was shit at mid revving and cruise.
Today found more infos on Factorypro website about ajusting carbs... If by logic everything is OEM as before Overhauling, the only thing left are bad ajustments... opened the float bowls today and , i don't know why, float level was around 11mm... reset them at 14 instead... put everything back on... Started engine do synchos with mixture screws still left at 3.25 turn... When on a ride, temperature was 20Cel... could feel that on cruise sometime, have some hesitations and some dead spots on accelerations... seem ok over 5500rpm... Back home, turned down mixture screws a 2.5.... When on a ride tonight (15Cel outside) seem much more better... Need to test it out at warmer temp...
