Okay, so I went to go for a ride this morning, started up the sled.....sounds prefect, I was letting it warm up and after about ten minutes it started to bog out.....then when I went to touch the throttle it went into safe mode and the rev limiter kicked in....I looked down around the powervalves and there was black carbon ozzing out around them....I had the powervalves and carberators cleaned and adjusted at the dealer only three weeks ago!!! I also checked the plugs and they were black and there was a lot of 'grit' on them.....what do you guys think?

thanks..
 

grit ??? sillver grit??? have you tried new plugs yet ???

Most likekly loaded up on fuel and oil if jetted too rich, too long of a warm up when temp are not that low is not a good thing...make sure it's not a stuck float needle...I would put in a new set of plugs and fire it up and take it out for a run, go easy on it till you vent out the lower end...post back
 
There are posts with guys saying they let there vipers warm up for 10 to 15 min..
Thats something i've NEVER done to ANY of my sleds
once the sled holds an even idle i give it about another minute and then we are down the trails...easy for the 1st mile then givn' 'er.
never a problem,
I agree, you just fowled a plug or 2...thats the 1st thing to check.
 
All three plugs are original....3000kms on them, the grit on them was pure black...looked like asphault! Temps here this moring were approximately -10'C

Something I also failed to mention was that I've used some regular grade Castrol oil the last few rides and have noticed a small difference when the sled is idoling during a cold start. I'm going to try the plugs and see what happens, I really can't see that being the problem because the enging was running smooth with no bog, all sounded good, the problem is when you hit the throtle the safe mode kicks in....

This might be right....but usually when you foul a plug the engine doesn't run smooth and it sounds like an old Bravo....
 
whoeever did the carb tune-up probably set the throttle cable a little too tightly when they put the rack back in....your TORS is kicking in

back the tension off the throttle cable slightly until it doesnt do it any more.

good luck

your TORS is kicking in. Make sure the two wire plug from the carb rack is pluged back together. If it still does it, then loosen the throttle cable slightly until it stops. If it still doesn't work, plug the two wires going to the carb rack together, this should end all problems, but dissables the TORS system.

Cheers, Steveo

have you rode it since the dealer did the tune up or is this your first time running it since then?

Since the dealer did the tune up I've put approximately 500kms on it....


Just to let eveyone know, last night I put the ol Viper in a heated garage for a few hours. I drained out the regular grade $hit oil from the reservoir and replaced it with Shell Advanced, I put some gasline antifreeze in the fuel, and turned on the carb heaters (something I never thought of the other day) I then fired up the engine, let it idol for a few minutes and then no problems!! I don't know if what I did helped or it was just being in the heat that helped but everything works fine now! Thanks for all your input...
 
Just had the same problem with a vipe lastr night there must have been water in the gas and it was froze up.
