Jetting RMZ 450

[oneduke]

I have looked at some other posts, and am fairly knowledgable about jetting but this seems weird. Lean condition with a 42 pilot so I moved up to 52 pilot. Still same lean condition, runs good with the choke on, turn the choke off and it all but dies when going from idle to wide open. Get the rpms up a little and it does ok. Seems like it shouldn't be that far off. This is ohio, no mountains or thin air. Any thoughts??

did you have the slide out?if so the vacuum release plate is upside down.

Thanks for your reply but unfortunately I did not have the slide out. I have not checked the accelerator pump, it is a brand new bike you would think it would be ok huh? Jumping from 42 to 52 with no difference doesn't seem right.

thank you

yes,thats not right.

has it been this way always?hot start sticking?

you should confirm that the plate is in correctly.the cut away goes down.

I haven't actually checked the plate, but I will. The hot start is ok. I will check it tommorrow.

thank you
