well my dad got back last night from running the new Viper engine. It ran great on the trails but on the lake it would only pull 7500RPMs way short of the desired 8500. 8300-8600 is the max best RPM range on the Viper. So it is time to get into it and see if they rejetted. Stock Jetting is I believe 49.5. Gonna check if they changed the jets around. As my dad said if they did he is gonna be majorly pissed.

I know exactly what the stock RPMs shoudl be 8300-8600. The old engine ran pegged right at 8500 at WOT. My dad took it to a dealer up north that sells cat, yammis, and skippys. they have a dyno so he took it to them to get it fixed. I am sure we could have fixed it but whatever. he called tech yet again and they said they would call back. /me rolls eyes
