gl1200I "87" fouls out when damp or wet out

Post by tolmstead » Mon May 14, 2012 2:30 pm

I have been looking for what may be the cause of this fouling out when damp or wet out.
The wires seem to be on good and tight, but after it warms up in about 10 to 15 miles
it will clear up. But not if its still raining or real damp out. Any Ideas before I start to get into it.

Under the rubber boot that attach both plug caps together,between the spark plugs,there is a drain hole.Be sure it's clear to drain any moisture that collects there.
2nd.While your there,remove that boot and put the caps back on the plugs,start it in the dark and lightly mist some water in the plug area to look for arcing.
Just a light mist,don't drench them.
My 1100 plug caps were hairline fractured,and any moisture around them and they arced right out the sides of them.
I replaced all 4 and replaced the wire too.They were cut to length and screwed on.One at a time.
