Hi guys i recently bought the first year of giannelli exhaust ( didnt bought the silencer , already have athena) .
And now when its warm and everything i want to nicely rev it and it almost stalls so i took it for a ride and when i WOT it kicked like crazy and went crazy fast but when i close the throttle, bike didnt go back to rpm and slowly stalled so i wanted to bumb started it but she didnt let me .
So i had to wait and then it would go but i want allowed to close the throttle.
So back home i switched the exhaust and it ran normal again but it was hella slow....
What should i do ?
( i run 30mm mikuni and have a little bigger hole in airbox)
