Hi all, just for your interest. Before I put my K&N filters on which btw I love, as I do the extra space. I had done that mod of cutting out the section at the bottom of the air box and adding a Unifilter.

Anyway, my point is a couple of years back I travelled for 4 hours through what was called the Newcastle floods with that mod and my bike didn't miss a beat. (see vid below)

I'm also old enough to know that one study or viewpoint is a good start to verifying this or that, but I also understand that there are numerous factors that determine good dyno figures too which has been discussed more than enough.

Again, I think the bellmouth configuration is a great mod with it's your beaut zip ditty doo dah venturi smasharooni effect but, and there lies the question, to really I mean really determine which way to go is best needs numerous studies properly conducted by non for profit agencies with no kick backs.

I'm not trying to say one is better than the other because I don't know. What I do know is many a company will push their product with their "paid for" studies to get the result to help sell their product.

I bet K&N could probably do the same.

In saying all this, it would be nice to know one way or the other but in reality there is probably not much difference at all between one or the other. What's important is we comment on our own experiences and let people manage their decisions from then on. Bob has mentioned his experiences and I'm just doing the same to help even up things a tad.

Anyway, here's that rain I was telling you about.
This type of rain I mean

One last thing which is but interesting I believe, that day I knew I would always have a shield to hide behind because my mate who didn't was saturated when we did finally stop on the northern beaches of Sydney. Me, just a few wet spots on the edges. Blo#dy beautiful. It was like "singing in the rain" Brilliant
