Ltz450 idles but dies when you hit the throttle

Recommended Posts

I’m working on my buddies quad for him and this whole fuel injection thing is all new to me. I’m used to carb quads. Anyway it idles fine when sitting there but as soon as you hit the throttle it dies. You can start it again but will do the same thing. Any ideas?

I'm no fuel injection expert but from numerous issues read common to FI dirt bikes, you can suspect:

 

-low fuel pump pressure

-blocked injector

-TPS sensor out of calibration

Replace the fuel filter, you will be back to normal....

Trust me
