I was cleaning the carbs on my stock 02 Viper today and noticed the main jets are 153.8. I checked the manual, and stock is 156.3.
This is only the second season I've owned this sled, and had no problems last year, but I'm not sure if this is a safe jet to run. I'm at 900 ft elevation, and the vent tube is plugged into the airbox.
 

even being stock people on here say u should raise your needles also, mr viper700 does a good write up on here
 
Yea thanks blevis, I just raised the needles today. Just not sure about the main jets.
 
someone jetted it down slightly, thats not a whole lot, youll be ok if you raised the needles and run decent gas.
