Sv 1000 spark plug foul!

I have a v strom 1000 with heads, throttle bodies, ecu, stator, rotor, wiring harness, switches from sv 1000 k3. Sometimes when it is cold and i want to start it the spark plugs foul out. Sometimes one sometimes both. As i can see the spark plugs are wet. From the exhaust blue or black smoke is not getting out. What is going on?? Problem with ecu, fuel pump, ignition coils? I have already clean the throttle bodies and injectors.

Is it something wrong with electric system? Bad connections??? What do i have to check?? Tthe spark plugs foul when it is cold and open the trottle to go almost immdiately. The spark plugs in my motorcycle are ngk cr9ek

CR9's are colder heat range than the stock recommended for the SV...which is an '8'. Considering that the DL pistons are even lower in compression ( I think...never played with them in person) it might even be good to go to a '7' heat range plug for your DL.

Rather than running the EK's (dual ground electrode) we've found the CR8EIX Iridium plugs work very nicely and were I you....I'd go for CR7EIX in that bike. This would go a long way toward curing the fouling. Best of luck!

On cold start, heat range should not make any difference. The heat range is a spec of how much heat the plug rejects to allow it to run at a stable temperature to assure it gets to the self cleaning temps and not too high as to burn it self up. It often is seen as how far up on the insulator the ceramic goes up the tip.

Which manifold pressure sensor are you using DL or SV?
Are you using the DL vac buffer in line to the sensor?

I would be checking the following
How old is the battery?
How does it load check?
Is your bike charging correctly?
Vac leaks?
Throttle bodies correctly seated in the manifolds and tight?
All the regular tune up stuff, throttle body synch, valves TPS and so on.
Do you have a PCIII or PCV or other fuel controller on it?
Make sure your spark plug end caps have correct resistance and continuity to the HT lead is good
Check/set high idle system

I have found many times FI bikes will spin over, but there is enough voltage droop certain parts of the system will no signal correctly and bike will not light up the ignition, but will be spraying fuel.

My battery is 4 years old but i think it s ok. I use the sensor in the airbox from dl k7. The bike charges ok.

I would still check the battery to make sure. As I said, they can spin fine but if voltage drops too far, won't fire.
I am not worried about the intake air temp sensor that threads into the box, they are the same. The manifold pressure sensors AKA intake air pressure are not the same and I think run different linear functions for their response.

How can i check the battery. Also i forgot to tell you that i have increase very very little the compression. Is there a problem with ecu?

Agreed. But...if the plugs aren't cleaning themselves during normal running and are accumulating carbon and deposits then they'll be more susceptible to fouling on a cold start. Especially if the FI mapping is on the rich side which most seem to be.

You should load test the battery. What is the voltage when the bike is cranking over to start?

I have run 9 series heat range plugs in several SV1000 stock street bikes w/o issue. I even ran 10s for week because it was all I had for my bike once and did not have issues. I have also run 9s in DL1000s too w/o issue.

How much compression do yo have? What did you do to increase it?

I do not know how much is the compression. very little increase. a light polishing to the head. as if to blame the battery ??? I am surprised that the spark plug foul only at startup. I think when i push the button to start the bike volt are ~10. I am not sure
