Jetting: Riva 784, stock 44's

runaway

I break stuff
While my stroker is down I want to run an old Riva engine I have.
Problem is I sold the powerbombs that were on it. Here are the specs.
784cc
34cc domes
case/cylinder porting (says "Race SL" on it)
v force reeds
speedwerx freestlye pipe
concord 13/16
stock cdi
lightened 62t flywheel

Been following the other dual 44 thread, but this engine is a little different, esp. sice its not running a b-pipe. I would hopefully like to run the 2.0 n/s, 95g spring. That has always worked well for me. Just some jetting #'s to start off with. Thanks very much!!

Oh and I believe these have return line restrictors.

i can give you what i would recomand if it was a type 9
i have not set up speedwerx pipe before

i would go for a 100 low
22psi pop off
115 high

this is for a type 9 and it should be close enough to get you going
