Lost Power On Viper

[jdp1under]

Hello Guys I Suddenly Lost Power On My 02 Viper Last Night After About A 100 Mile Ride In 10-15 Degree Weather. The Sled Bogged Down I Pulled Over And Cooled It Down It Wasnt Hot. I Changed Plugs And Started And Tried To Ride It Sounded Really Deep In The Exhaust Like A Four Stroke And Would Only Hit 6500 To 7500 On The Tach At 30 - 40mph. Im Thinking Powervalves I Had To Ride This Way For A Mile Or So And Put It On The Trailer. It Starts Fine Coolant Is Good And Plugs Look Ok. Any Suggestions!!!!!!!!!!!! Thanks

When mine sounded like that it was the air filter packed with an inch of snow and ice , so no air was getting to it. But i'm sure you've looked at that.

Heated Carbs

Just wondering if you had the coolant to the carbs turned on to prevent fuel freeze up.

I'd say powervalves aswell...I remember my first ride on my vipe and it rocked. Then I took the wife out.and either with her on or off...and the wind behind me I couldn't get it past 80...after further inspection the valves where stuck half closed...I now check that regulary...and even check to make sure they are flush...

The tech section i believe has the fuel pump upgrade. easy to do.
