My Gilera DNA 50 is really annoying me now! When I go over 40 mph on it, it often cuts out
I have cleaned the carb, had it up jetted, had a new fuel pump and it still cuts out! It happens 8 times out of 10 when i go over 40. What happens is i can feel it going to die so i either keep it twisted back or i release the throttle. either way it dies or it dies then comes back to life then dies again etc. I have broken down about 15 times since i had it and its doing my nut in as i normally have to wait about 5 mins before it start up again!
I was thinking that it might need up jetting again?
anyone got any hints/tips
