GP1300R 00' single pipe jetting
I'm going to install an OEM 1300 top end on my ski and need some jetting specs. I want it to run a bit fat (reliable).
Ski has: OEM cdi modded by protec, 150 psi stock milled head by lowell, riva flame arrestors, stock carbs WITHOUT choke plates, accel pump disabled, stock pipe D-Plate
33:1 Fuel/Oil ratio and will do some drilling to allow more air flow
Searching and asking here is what I'm considering, let me know your suggestions:
1 1/2 highs

I recently bought a set of new 1.5 N/S, is there any way to make these work ok on the 1300?
1.5N&S, blk 80gr, 120p, 130m ???

The pilot is too big, need 115 and that is on the large side but tuneable for a non ported 1300 ski. the 80 may be fine, have to try it to find out. It may come on late in the midrange.

I ran 1.5 n/s, 42 psi popoff, and 115/130's for four years with no problems. I think 135's are way too big for a nonported 1300 with moderate compression, but it's up to you.
