mis when wet

[Reed]

My 08 venture, when ever I ride in the rain or wash my bike the right rear cilinder stops firing. blow off the cap & around the plug & it starts fireing again. I have checked the drain hole it is open so that is not it.what else ? I am thinking that the rubber on the cap is not sealing. so I put some grease in the cap & put silacone around all the places where the wires and ruber boots splice. Havent tryed to wash it sence. the silacone isn't dry yet. so dont know if it helped yet.

thank you for your input!!!

Sounds like you may have a damaged spark plug cap or sprk plug lead which is allowing the electrical to flow to ground when they get wet.

You could put the bike in a dark area. Then yse a spray bottle to mist the area and see if you get any corona.
