my fzr 2009 works fine in idle , when i accelerate it hesitates till rpm 4000 works perfect at high rpm and reaches top speed fine .
1 spark plugs replaced.
2 fuel injectors cleanedclean tested.
3 no water on spark plugs.( inter cooler is fine )
4 no smoke .
5 reaches top speed
6 woks fine on high rpm .

it goes like bo bobo bobo bo bobo . and when i increase the speed it goes fine till top speed.
