I'll take a stabb at it.
mix a 40-1 in fuel to go along with the oil injection 93 octane
See if it runs ok at that adjust iff too rich....

i'm still using the oem pistons that came with the ski. i took it to our yamaha mechanic and he said they were in spec and i will be fine but i will need new rings. so i got new base gaskets, exhaust gasket, head gasket, and rings.

so old pistons and new rings?

yes old pistons and new ring. before i sent the cylinders off it had 150-150-145 compression.

The new rings will have to seat, so maybe run 10gals of 32:1, then work into 40:1
I would start the controller at 7-8-8-6 for break in and lean it down after you run the 32:1 out

after 40:1 then what? just regular gas? will the breakin be done after 40:1?
