That's my feeling, too, if the Moco sells them with the kit, they should do the job.

Perhaps should I consider to buy a pair of hi-flow injectors to help ?

It is particular to mount such a kit with stock injectors, what do you think ?

 

Hi, I bought the Hi-flow injectors (5.3g/s) and that is THE thing to do.

Mounting no issues, mapping without problem, I have a little job to do to make it perfect, but already a good start !

 

Getting the idle right is the most difficult. If you don't go to a tuner and want to it yourself you may want to start by setting your idle at 1300 rpm or higher. This will make it easier to tune. As well do the tuning when the bike is warm, not cold. When you have reached a good idle you lower the rpm gradually and adjust as you go.
The throttle response you can do at a later time.
