When I had my Norge the bags leaked and I complained. Turns out there is an Aprilia part number seal that goes on the bags and seals much better. I would only get a few drops inthe bags after installation to the point where I wasn't sure if it didn't just drip in when I opened them. I had to pay for them but they were cheap. I posted the part number on the Norge discussion. I am at work now and don't have it handy.
