I have a Viper mainly stock except a silencer. When I go full throttle it rev's to 8200 then falls off to about 7600. I checked both clutches, put in a new belt. No change. It seems that the motor is suddenly loading up real bad. Any Suggestions???

just for $hits and giggles, throw the stock silencer back on and report back on the rpms.

how are the power valves? dirty and stuck? any pull-thrus on the cables?
 
This same thing happened to me a few wks ago. let me ask u did u take off your carbs and clean them lately? Dont know what i was thinking but I put the brass pieces that scew in with the main jet on backwards. must of had a brain fart. Same symptoms of my sled though..drf
 
Got it fixed, dropped the needles and adjusted air screws runs good now

if your sled is stock, other than silencer, there is no need to drop the needles on a viper, from the 3.0 position, which is clip in middle groove and both washers underneath. your sled will only be faster for a while, then.......sqeek.
