does anyone know where to start for jetting a riva red pipe? It's going on a stock 2000 sj.

I just pulled one off my ski. It was running great and pulled hard. I have a different prop too but jetting should be close enough. These are the same specs that Riva gave out with the pipe install and they were bang on for a stock boat. I turned the LSS in slightly just to crisp up the bottom end.

stock Dual 38's with choke plates intact and Riva Flame arrestors
Main 130
Pilot 70
N/S 1.5
Spring 95
LSS 7/8
HSS 1 1/4

Hope this helps
