Re: Recommended Jetting

Needle jet = emulsion tube.  At one end screws in the main jet, at the other end the needle slides in and out as the slide moves.

The different emulsion tubes and needles are related to the slides. Mine is a 1984 FJ1100 with the flat bottom slides and the emulsion tubes have no flanges (shrouds) at the top where the needle slides in. My needles have only one clip slot also. I think the flat bottom slides were only used one or two years, 1984 and 1985.

1985 slides are the same as all other years.  '84 had unique slides, emulsion tubes, and needles.

I wouldn't mix components.  Pick a year's components and install them as a set.

Thank you for clearing up the emulsion tube question and clearing up which is the main jet. :flag_of_truce.I have been busy and have not had a chance to pull the carbs yet.I have to get my Rodeo running right to haul my waverunners to the river so I can break in my 170 hp 2 smoke motor before I have to put them in storage at the end of the month.I will certainly look at the emulsion tubes when I get a chance and check the main jet to see whats in there,that and the float height.I might be over rich on the air fuel mixture jet as well I am out either 3 or the 3 1/2 turns that dynojet recommends.

Float heights are important. Set your floats to 23.0mm. The manual says the float range should be  21.3mm to 23.3mm
I was surprised to find that my floats were set to high (@~20.0mm) so I dropped them down to 23.0mm and the slow speed stumble went away.
The Factory Pro folks say that floats set too high, is a common problem with our CV36 Mikunis.

I've always wondered if raising the rear end, via dogbones and Penske, magnified the incorrect float setting. All is well now.

Cheers!
