2007 Yz 450f

Recommended Posts

I have a 2007 Z 450F with a 165 main jet.

The bike popped alot on decell with the stock 160.

Bike runs very well but the pilot screw makes no change when going all in.

Do I need to change another jet?

Thank you

main jet has nothing to do with any thing that happens with the throttle closed.

if the bike idles with the fuel screw full closed you need a smaller pilot jet.
