Mexico yamaha bws 125cc

hi

 from mexico I have a yamaha BWS 125cc scooter 2009

perform an upgrade of cylinder 155cc, High Camshaft, oko 30mm carburetor but when it reaches a speed of 100 kph is a failure as if it were injected fuel or have ceased to flow

I commented that perhaps it was necessary to change the cdi but here I found a piece that I think you could argue that

 

 the piece is Malossi CDI RPM Control or some other piece that I recommend you

greetings j
