08 TE450 Starts, revs, dies immediately...

I searched and searched and found nothing…
Worked fine yesterday, this AM when I try starting it, it fires up, revs super high, then dies…

Happened about 6 times before I stopped trying.
Any ideas???

Thanks-

Intake manifold leak? Check the boot, grab the throttle body and really give it a tug backwards, up and down, side to side, look for cracks in the rubber as you manipulate it.

Thanks, I'll give that a look when I get home... Hopefully it's something simple and not an EFI / throttle body issue.

When I got my bike overheated and damaged the intake manifold, it ran fine until one day, on a ride, the thing separated and left a bit of a gap, the bike wouldn't start, I jiggled the choke or something and then it started and revved to the moon, then died. I reached down and found the damaged boot.

That was the exact problem. Thank you sir, you are awesome!!!

Was it loose or cracked or what?

I'm embarrassed to say that after I put my engine back in, I failed to tighten the clamp around the intake manifold. Odd thing was I rode it yesterday with no problem, went to start it today and it must've popped off immediately...

Thanks again!
