Hey guys. I have an odd problem going on with my viper. i will be riding and every now and then it just feel flat. It will only build to about 7000rpm. it will be like that for a second or longer and then all of a sudden it jumps to 8700 and has tons of power. I am running Aeen triple pipes for the last couple years with now problems. I cleaned the power valves 50 miles ago, carbs have been cleaned, clutches gone through. I just dont get it. It is almost like one cylinder dies for a short time. Any ideas? Would a pull through power valve cause this? the only other thing i thought of was something with the coils or ignition. But i dont know where to start with that. Any help would be great. Thanks in advance.
