I have a 92 SP that is very hard (almost impossible) to start when warm. I have replaced or repaired the following:
-New fuel filters and hoses (including fine mesh filters and pick-up hoses in
tank)
-New fuel selector valve
-New plug wires from coil to plugs
-New Oddysey (13 volts at rest) battery
-Rebuilt Mikuni SBN44 carb (settings; LS 1 1/4 turns, HS 1 turn out) twice
-Replaced 2.5 needle and seat valve in carb
-Pop-Off pressure 20psi (115 gram spring)
-Replaced rotary valve cover (SBT) and valve (clearance was 0.015")
-Compression 140 mag, 145 pto
-Ski has a Coffman pipe in addition to the SBN44 as the after market
add-ons by the previous owner.
Ski starts up fine (it has a primer) when cold, and on the trailer. Run it around the lake and it screams, no bog, no hesitation, turn it off and you have a hell of a time restarting it. I've played with throttle settings, carb settings, priming, you name it, no help. Last week I took it to Lake Mojave after replacing the rotary valve cover and valve. No improvement, although it did seem to help in starting if we lifted the rear end while attempting to start. I also played around with hanging over the handle bars while starting and it seemed to help a little bit. Although by now I may be imagining things. Once we did get it started, it ran like a champ (good idle, no dying) until we shut it down then the whole procedure was repeated. I will say one thing, that Odyssey is one heck of a battery. I must have cranked it a hundred times and that thing never let down. Does anybody have any ideas where I should go next?
