starting to get the viper ready for the upcoming season and it starts up right away but then shuts off almost immediately. the light is very very dull and the gauge doesnt light up at all, do i have a stator problem? it started a few times and ran fine for a sec then acted up like the tors was kicking in when i would give it a little gas, disconnected the tors and its the same. i dont know where to look.

Plugs ok - do you have a good spark?
sound like you have rust on the mag, and the pickup coil is not getting a good contact.

are your sure its getting anough full do a couple pulls holding the throttle wide open with the kill switch on to see if the plugs get soaked in fuel.

its getting enough fuel its got 165 mains 50 pilots, but i wouldnt be able to check the jetting cause the sled wont stay going long enough to get the clutches to engage.
check your throttle kill switch on the throttle block, they are made so you can use them as a teather. you can start sled, hold throttle a little, then hit the kill switch. if you fall off or release the trottle, the sled will shut off. when they go bad, what you described is just what happens.

but i got the tors overrided, is that what you are talking about?
no, this is separat of that. this is in the kill switch itself. if you pull your throttle a tiny bit, it pushes a plunger that is connected to the kill switch. when you push down on the kill switch after this plunger is ingaged, you now have a teatherless teather so if you fall off sled. sometimes they fail.

That is interesting, and I did not know that. I will have to play with that and give it a try.

okay, so if i unhook the kill switch this will test to see if that is what it is right.
Not to insult you, but did you do your carbs this year, powervalves working, exhaust plugged?..had to ask...look inside your air box & see how open your carb sliders are at idle, what do your plugs look & smell like...does it just fires up & when you pull the throttle it just stalls out?..is your oil cable stuck full open?..

I also find this interesting. Not to try to hijack the thread, but what is the reverse procedure to get it back to normal if I were to try this out? TIA
Just pull out your kill switch, fire up the sled and kill it again with kill switch, to activate, while driving just hit you kill switch, it does nothing until you let off the throttle completely...

carbs were cleaned, new fuel, new plugs, airbox was cleaned, pipes are clear. everything is cleaned and cleared. gonna have to figure this out soon. im thinking maybe its the stator.

??? I was just thinking more about this, I've done many jetting checks. Hold the throttle at whatever position of the jetting I want to check for quite a while and then hit the kill switch and pull plugs. I've never noticed my sled just die when I let off the throttle afterwards, shouldn't I have "accidently" activated this when doing jetting checks? Funny that I've never noticed that my sled seems to die a lot after checking jetting. Actually another thought just occurred to me. It must de-activate its self after the sled dies, otherwise you would have tons of people pulling on their sleds with the switch in the on position and it would never start until the switch was pushed off and then pulled on again. OR, maybe that's why we have to give our sleds a little throttle on occasion to get them to start? Pushing the throttle a little hits the plunger and de-activates it?

Sorry, not trying to hijack your thread.
So, the sled starts for like one or two seconds and then dies. Right after it dies, pull the plugs and see if they are wet or not. I'm just speculating here, but I would think if the plugs are wet then its probably a spark problem. If they aren't really wet, then maybe its a fuel problem, like your fuel pump is dying.
I would definitely by pass the kill switch and eliminate that first. Might as well try the cheap, easy stuff first.
