Hi guys its me again...

I just got a new FPR,4x NGK Iridium new air filter..

And i start my bike so it throttle again from 1200 to 1500 rpm

And afther that its going so good not any problem after 1500rpm

its just from when i start to ride from 1200rpm to 1500 its throttle.

Is there a way to configurate the Fuel Injection System or just synchronize them ? Maybe that is the problem ?

 

There is a way to sync the throttle bodies. It takes a special guage that screws into the sync ports.
