Never had any problems with rain on my bike Big Sucker on my Lowrider (carb'd) and the SE on my EG Standard (FI), with a cover similar to Neggy's. \\; While it doesn't rain often here in Arizona, when it does it's pretty torrential, and \\;I've been caught in the rain on \\;both bikes. \\; No hesitation \\;at all on either.

I'm on my 2nd Big Sucker. My first had a billet cover (Softail), my new one has the football (flht). I get caught in thunderstorms often, with no problems to report. You need to remap.
