OK back to the perry pump questions.
I have the vp -22 shaker pump installed with the moki.I did notice alot more power and better performance.My question is do i need to run the back pressure line from the muffler to the tank still with the shaker pump?I have tried it both ways with it the idle is way up,without it the engine loses some of its power that was gained.Any help would be greatly accepted.[sm=confused.gif]
