issues with starting the bike

[GrimReaper]

Thank you guys.I spoke with a local felow airhead today(respectful wrench-German guy) about this and he suggested since i took out only the idle jet,just to put the cables back and set the throttle ones with 2mm free play.He said no need of synchronization.
  I did it and the bike ran like never before.Nice smooth ride which was disturbed by a stuck needle,which i noticed very quick and fix it on the road.
 Anyway this homemade manometer is very cheap to made so i am going to make one tomorrow and see what is going to show

With all respect to your German mechanic friend, by using the manometer, the best performance improvement will be adjusting the throttle cables to balance the carbs at 2500-3000 rpm. This will have both butterflys open equally at cruise speeds thereby smoothing engine ops, less vibration.

Engine must be fully warmed up prior to tuning/adjusting. Big fan to keep engine from overheating. Run no more than 5-6 minutes before allowing a short cool down, then restart and continue, if necessary.
