SLP Viper jetting

Anyone use Slp pipes on viper with ported cylinders and case? need some help with jetting/carb setup. greateful for any help

I presume nobody has ported cylinders/case then? What size jetting do you use with stock engine and slp pipes only?

Here Ya Go

Have 02 Viper with SLP's. Stock motor. Cut head by CPR to get equal compression. About 130 on all cylinders. Have Temp-a-flow, rear exchanger, and Opticool gasket.

160 mains
3.5 stock needles
47.5 pilots
2 1/8 fuel screws.

Might be a bit lean for you app. Most set up's tell you to richen the Mag., but since I have same compression all the way across and all that cooling stuff, I set jetting the same all the way across. Rode last weekend in +5f to -5f with no problems.
