I bought this from Casoli USA for my 748R, but never put it on, nor do I really plan on it. It was an impulse buy. Also included is both of the tubes need (to the air box, and from the crank case) one has a small crack at the end but I don't think it will matter if properly clamped on there.Oh they are clear as well. I got it through one of their auctions, which said it was new, but I don't believe it is. It smells like it has been used and it has a mark on it which you can see in the picture that suggests it has been used. Any way I'm asking $375 shipped in the US if you pay with paypal to [email protected]. You can also email me any questions etc... there.
