So, I have white moist smoke/steam coming from the exhaust on start up. I will describe now. Link to video: The bike starts up with no smoke at all. After a minute or two the smoke starts to billow out the exhaust. It takes around 10+ minutes to finally dissipate. Once it has finally ceased, there is no more white smoke for the duration of operation. If the bike is left to sit for more than 10 minutes, when I restart the smoke appears again. There is moisture spitting out the cans when the bike is warming up. It has soot in it, no oil. Once it is above 80-90 degrees C° it will cease. Please add any comments or advice so I may correctly diagnose the situation I have.

DannoXYZ and Grum, I will post again in a couple of days and touch base with how it's going. The two of you are an invaluable asset to anyone one here. I appreciate the time you've given up helping a stranger. You have restored my faith in my fellow man ..👍

Ok gentlemen, there is fire. After digging and digging, we've found it. I was able to borrow a vacuum gauge. 👍 After so many floodings and flood procedures, I decided to just get all new speak plugs. They were always oil/fuel covered and had to be cleaned off. The new ones in this started some coughing and sputtering. I removed the air box again and check all the throttle bodies to make sure they were all secure. Restarting the bike it fires but wouldn't run, so went over the vacuum lines again. The map sensor hose pressure was zero, so I took the throttle bodies off again to check where else the hose was going too. "THEN I FOUND IT": A random 2mm hose spliced into the the vacuum lines. It had been hidden by being taped on with the throttle body wiromf/ FI wiring. The previous owner has put one of those shitty Scott chain oilers on the bike. I domy use it. Who ever installed it had spliced a T section into the vacuum lines underneath the throttle body, but because the had taped it all up with the wiring harness I never saw it. Who knows why they did that? I guess it was to stop it from falling off and dripping the pressure, (which it did). I pulled the t section out, joined the two hoses and BOOM! FIRE!!!! Whoever fitted that ridiculous oiler onto the bike added it to the vacuum lines. I want to find them and give them a proper beating. Who tapes an auxilry hollow tube for an oiler onto the MAP sensor Vacuum line. Morons. So after all the testing and strippimg things down and reassembling, we have ignition. I must add though, now it's running again, I have alot of moisture coming out of the cans. Until it's up to about 80°C there is white moist vapour coming out. Didn't have that before. Once it's hot the moist white smoke/steam is gone but I don't like moisture coming out of my cans. The fuel is shell optimax 99 octane E85.

Hey mate, The fuel pump always primes and is delivering fuel to the valves. I'm sure I did mention it in the earlier threads. Regardless, the fuel pump primes and pumps fuel👍. The plugs were black and had oil/fuel on the electrodes and protrusions. I'd be assuming from flossing the engine. A couple of times now. I've come inside as it's snowing right now. 🥶

Ok, thanknyou very much for clarifying that for me. I'm just pulling all the spark plugs and giving them a clean. They all spark, but just checking them all again. I do however keep draining the battery and am requiring full charges every night.

From what the diagnosis so far has told me, is that there is one of these.: show loose connection, open or short in yellow/red wire, and/or loose or poor contact with the ecm connectors Am I / is the result, in taking the information from the service manual with the results observed, correct? Should I continue with the rest of the procedures? Even though I don't have a vacuum tester or a testing ECM harness.

So to clarify with you Grum, Having no MIL Blinking after the first step means there are faults or are you saying there are "no" faults, i.e. this shouldn't effect it starting?

Hey guys, I have done multiple flooded start procedures with no result coming from it. I don't have any vacuum tester or compression testing kits. I have started with the fuel system troubleshooting. Step 1: MAP sensor connection inspection: Turn off ignition, disconnect MAP Sensor connector, check for loose or poor connection on sensor, Reconnect MAP Sensor, place motorcycle stand down, Start engine,(obviously not firing when I do this), is the MIL Blinking? Answer: No, with the bike as is. (Yes, if I jumper for error codes?) Step two:MAP Sensor power input line voltage inspection: Turn off ignition, disconnect MAP sensor connector, measure voltage at wire harness side. + To Yellow/Red terminal, - to ground. Is the voltage between 4.75 - 5.25V? Answer: No, when ignition off. (Yes,: 4.98V when ignition on). I have not done any further tests as those first two show loose connection, open or short in yellow/red wire, and/or loose or poor contact with the ecm connectors. I eagerly await your responses to this information.

Hopefully we'll get lucky and find the root issue. Thank so much guys👍

Ok mate, that's the next step, but it'll have to wait until the morning. It's -3° and dark now

Hey DannoXYZ, I have been readimg through the manual also, but am thinking maybe there is something I've missed? To have fuel, air and spark, we should have ignition? Anything else you can throw at me I will gladly honour and do that procedure.

Hey mate, I cleared the codes already and no fire.

Hey guys, As always, thank you so much for your input and time. Your helpfulness is not unappreciated. It is welcomed. Firstly, To answer your question DannoXYZ, *I have since jumpered the ECU and retrieved the error codes. *I do not have a compression gauge. I did the old school trick of placing my hand over the intakes and feeling for compression. All suck down hard and effectively. *I have a good multimeter *No, I do not have an oscilloscope 👎 wouldn't know where to start with one. Secondly, I've run through all the error codes on the bike. Checked them against the service manual and they are what would be concurrent with everything that I had unplugged whilst doing the throttle bodies and testing. Noting out of the ordinary. If you'd like to know, they were: 1, 2, 7, 8, 9, 12, 13, 14, 15, 21, 22, 23, 24. Everything that would cause errors due to removing the throttle body and all the applicable sensors. Obviously while having power to the bike these have caused such error to the ecu. The fuel in the bike is good, it is pumping to the valves without interruption. The bike also hasn't fired since it first cut out completely last Friday. After it cut out, I then tried to restart it twice. That is when it had some coughing spluttering. But, since those first to attempts to get an ignition, there has been none at all. No coughs, no sputters, no firing of any sort there is no fuel smell in the exhaust. Well, that I can tell. It is super windy here and now also -2°. I am totally stumped. I guess it's time to call someone and shell out who knows how much?

Hey, The spark is blue. I tested by removing the coil and using a screwdriver and the frame. Cranked the engine and observed a blue spark. Plug were done in July last year. Denso iridium.
