Hi guys,
I am trying to figure out the exhaust setup on my xp, I think I am pretty close now. I have installed a coffman rec pipe, ocean pro flame arresters, and have a stock waterbox with the water reg removed. I am trying to figure out the routing for hard jetting my water system.
Basically I have the stock t fitting between the pump and head that leads to a Unjetted plastic t fitting that routes to my manifold that has its own jetted t fitting, then I have the other end going to my jetted t fitting, which goes to my waterbox and tail cone.
My question is what size jet am I supposed to use in these? The documentation from coffman says use a 65 main jet, but that is awe fully small, and various posts online talk about using 165 to 190 jets. Does anyone have any experience in this area? I have my stock 142.5 main jets I can use, is that a good starting point?
Thanks in advance
