Water In Fuel: 2014 Griso 1200SE

Hello,

My griso has had a seemingly common problem where it runs poorly after being rained on. (Not that I leave it out in the rain regularly, but sometimes it happens, like if you ride to work and there is a mid-day t-storm)

Forum research shows that the common cause of this problem is water pooling inside the spark plug holes and shorting the plug out. I checked for this problem and found nothing. I next drained the gas tank into a clear container and found a considerable amount of water separated out of the fuel. Because fuel floats on water, it doesn't take much to make the fuel pump pick up nothing but water, causing the bike to not run/run poorly. Fresh gas in the tank and it runs great.

Has anyone else dealt with this? It seems like the water must be coming in through the gas cap seal, but nothing looks off about it on quick inspection. Is there another route for water to enter? Is the seal replaceable?
Thanks!
 
There is a drain for pooled water in gas cap area, exit hose is molded on the inside of tank and has a barbed fitting on the back of tank. Same with the cap vent for EVAP system, it's on other side of tank in the back. Both go through the inside of tank.

I have swapped out a couple tanks under warranty for those hoses leaking on the inside of tank. To check put compressed air to drain hole in cap well & block the barbed fitting and look for bubbles in the fuel. If this line gets blocked it will seep in through the cap even if it looks sealed. Hope this helps.
 
I experienced this problem on a Breva 1100 some time back, and it turned out to be the tortured drain in the cap well. It was clogged solid, and compressed air would not budge it.

I cleared by slipping a piece of speedometer cable into the drain, and driving it with a battery drill. Cleared and never repeated. Dunno what the crap was in there, it was a sorta clay like appearance.

I don't know if a wasp can get to the drain but there are some that lay their eggs in holes that size and then cap the hole with clay. I see it often in drain holes for windows. They even sell nesting boards with different size holes to encourage wasps which are pollinators into your garden.

That makes sense. This was when I was keeping a Breva in Los Angeles, very seldom do you see an insect there. Still, I wouldn't deny they exist.
