Bike revvs high after I let go of the throttle, dies after

[djg42]

I just got another GS450. It has emgo pods which IT wasnt jetted for so I decided to put the airbox from my old GS450 and make this one stock.
Now that i have everything back on its hard to start, dies as soon as I let of the throttle, and the revvs stay high for about 3-5 seconds after i let of the throttle when in neutral.

To put the airbox on I needed to take out the camshaft tensioner, did i mess sonething up putting it back on, could that be responsible? I tried pushing the slides up to see if they are returning normally and they seem to. Theres no backfire or popping.

Any ideas would be greatly appreciated! Thanks,
DG

Was it running with the pods? The way you describe it revving up and then dying out sounds like bad intake boot o-rings to me but I'm sure someone else will have other ideas. Could be that the stock airbox and filter are creating more vacuum and sucking more un-metered are past the boots if the o-rings are shot.

smart, i bet thats it. I had to take the intake boots out to get the airbox in, and screwing the intake boots is really hard to do with the airbox in-theres hardly any room. Im gonna try to tighten those screws down and see if that will do the trick.
Thanks!
