Hey fellas, The title explain quite a lot. In the beginning, when it was raining ( or even just a lot of water on the road), I was losing power. I suppose losing some cylinders. Now when it's raining the bike can't even start. If it has been raining a lot overnight and I try to start it in the morning, I need to use the starter with some gas for a really long time 5/10 minutes ) at some point it will start on one (two or three ?) Cylinders. After driving for 5 min and heating the engine all my power comes back little by little. Two observations tough : My coils and wiring seems properly sealed, can't see any sparks anywhere. I removed the coils, clean the contacts and I can't see any cracks. By removing the wires on the sparkplugs, they all spark when my problem occur. So again seems like my coils aren't shorted or cracked. - my airbox and carb intake is dry, so there is no water in these places ( and air box filter is sealed to the carbs properly now). - lot of my electric cables behind my headlight are in the open air, so completely wet when it's raining ( however same problem when the road is wet, without rain, so I don't think these cable have anything to do.) As my power start coming back little by little when I drive, I suspect water in my cylinders what do you think about that ? But where is this water coming from ? The bike is starting without a single problem when it's dry. So I'm really out of option. Happy to hear what you think about that ☂️ Forgot to mention : when I check for sparks by removing the cap on the sparkplugs, I can see clearly the spark on the second cylinder, however for the others they are really small sparks, I need to get it really really close from the frame to see a tiny spark. By writing this, I feels this could be my issue.
