T595 Rain Problems!

Baron
Yes silicon spray will help even plusgas. And yes start no throttle unless it needs it just choke on and fire it up. Also you need to check the plugs are compatible as someone may have been retuning and jetting.

How’s it run when you get it started?
You definitely need to get it covered up, any bike will deteriorate quickly out in the elements.

 

No choke on this EFI bike @joe mc donald

Are you possibly getting water into the tank @Baron
Check the nipples on the left-rear side of the tank right at about the juntion with the tail piece - those should have hoses on them that are directed down to ground just in front of the sprocket cover. But the important part is that they are not occluded (one is the vent for the tank, to backfill air as the fuel depletes; the other is the scupper drain from that well around the filler. Unscrew the nipples and see if those themselves are plugged and if so, clear them - but you also need to be sure the tubes themselves are not plugged - be VERY careful! the tubes go from where the nipples screw in, up through the inside of the tank to the neck - you must be super-careful not to puncture those tubes!! Try a thin wire through and hopefully you will not meet resistance (or at least something you can dislodge). With the nipples back on and a hose attached, check that you can blow up through them.

Next -Generally stick coils (particularly those used on your bike, that have seals) do not really suffer from the same 'damp' issues that remote coils with HT leads would suffer - unless water is actually getting down into the well
So check the plug wells - is water getting in there? Check that the rubber coil seals just below the cap are in good shape (oddly, it does not appear those seals are available as a replacement). But be sure the coils are actually bolted onto the cover.

You mentioned changing hoses - I presume the Idle Control hoses - on that note, how does it idle when it IS running? Is it working correctly? When cold you should get a 'fast' idle (about 16-1800 depending on how cold it is) then it should gradually come down to about 1250 when it's warmed up; if its not doing that , then there may be a fundamental issue with the idle control system.

Now - is is definitely a WET start issue? Or more just a 'cold' start issue?
They are typically lean anyway and when cold can be difficult to start
There is actually a minor table in the ECU mapping (the Warm-Up table) that can make that better - you would need the TuneECU program (and either laptop or Android phone/tablet) and cable to be able to change that.
With that tool, you would also be able to check and zero the TPS as that could also be making it a bit lean. And there is one more setting that can be adjusted called the Idle Fuel Trim (aka CO adjust) which can also make it a bit richer in the idle and off-idle - if otherwise running well when warmed up, I prefer the warm-up table adjustment as it ONLY affects the cold-starting air'fuel ratio and not warm running.



^ You increase the values of the cells in the 'cold' region (these are coolant temps, so your 'cold' temp is going to be pretty much what ambient temperature is - I suggest up to 14 deg to 1.25, 24 to 0.75 and 34 to 0.5 for starters and see how that goes (you have to save the changes and re-load the new saved map)

Check the CPS (Crankshaft Position Sensor) gap - that is behind the clutch cover (the guitar shaped cover) toward the front - that should be 1.0mm - that can also have a big affect on clean efficient starting.

Lastly the battery condition - does it crank strong at a good rate? If it's laboured then it may be past its best. If it has laboured cranking, then the voltage available for spark is likely to to be low.
There is a mod you can do to add parallel cables between the battery and the starter (three actually - one battery + to solenoid; one solenoid to starter; and one battery - to engine ground) Adding 8 or even 6 gauge cables in parallel to the OEMs will do it - you can probably get a car stereo installation shop to make those up for you. (I could direct you to mail order here in States but not sure where you would go in UK -maybe check with Kojaycat - see if he will make up cables for you, he sells the wire and terminals .....)
That makes a HUGE difference to the cranking speed, which itself makes it easier to light off.

Good Luck - hopefully some of that will bear fruit.
