This may be kind of vague, but this happened twice last weekend while riding my viper.

I was going along and all of a sudden it bogged down like it was running on one cylinder. this was not a wide open throttle but just cruising down the trail at about 20 or less. Sled was warmed up.. i let it bog then i hit the throttle and it corrected itself almost like it was a fouled plug. But then it ran perfect all day long. Any ideas? This happened twice about 6 hours later was the 2nd time.

I didn't change plugs this year.. (i know), should have.. but didn't

could it be a plug starting to fowl or could it be water in the gas etc..???


any help would be appreciated.
 
Could be any of a long list of things ranging from trivial to serious.

I would get someone knowledgeable near you to take a close look at it for you as there are several guys on here in your general area.

Next time it happens, stop immediately and check all 3 plugs. The condition of the plugs may help point to the source of the problem.
 
Where were you riding? If it was in the powder it may have been the "the forced snow injestion." I was getting a lot of that (rough running) in 10" of eastern U.P. powder last weekend, then it ran great back on regular trail.
 
actually this was just going down the trail. No real snow dust.. It was somewhat warm outside however. probably around 30+ degrees.

when you say serious? what kind of things would be serious?
 
Anything that starves one of the cylinders of fuel can be serious as it can lead to a burn down. If it is only a quick bog (1 - 2 seconds), then this is unlikely. If it is electrical related it may quit altogether at some point and although it likely won't cause further damage it might leave you someplace. If it is clutching related it should be leaving evidence.

If it were mine I would go through it using a simple process of elimination. If you didn't change your plugs, chances are you maybe didn't clean the carbs either. Maybe there is a little crud in one of them that is occasionally plugging one of the fuel circuits. Fuel related problems are the ones that can cause the most damage.
 
oh yea that is definately an easy thing to check if it is the TORS, it is probably because your throttle cable is adjusted too tight. Try loosening it somewhat, and see how it is then. Like others said, there is a long list of possibilities as to what is going on here, but this is an easy thing to check.
 
Good input on the TORS . . .

If you push the throttle just right it will activate the TORS as it thinks the throttle is jammed or stuck. A tight throttle cable makes this more touchy. My throttle assembly actually has a crack in it so I am running with TORS disabled until I get a new throttle block. Too many rolls down hills I guess.

IMPORTANT NOTE !!! If you do disable the TORS, make sure you know where the kill switch is and be very good at hitting it in case the throttle does stick.
 
happens to mine with the pipes on nopw, to rich at 1/4 throttle, starts adding to much fuel, the n you punch it and it cleans out and gos
