In my VR, I cut the bottom of the box (under air box), and I discovered the wheel was there, I'm thinking it would give wind up the filter. So I meshed the cut (so debrey doesnt get in), cut the bottom of the plastic air box and relocated the windscreen wiper bottle, and now it has a nice sound at 3000 revs and when I am climbing hills, it holds on the current gear longer without it shifting down to get power. But the downside would be is that the air filter will get dirty quicker and water would make it's way up.
