Just picked up a 04' viper and was curious top speed on these sleds. Also does a roller secondary give any more top end or just good downshifting and backshifting. Thanks Much, Aaron
I have a 03 piped mtn viper and with a 144 track I got 102 and with the 159 I got 94 not much of a help but if you don't get alot more than that you have a problem
