I have just been looking through some pictures from Donnington last week and it looks like the R1 Dax had a scuttle mounted fuel tank! Can any one confirm this?

(there is a photo in my archive)

Yep the Dax does have the fuel tank up around the scuttle somewhere

I've fitted a carb'ed engine to my car. The original bike didn't have a fuel pump. In the interest of lightness (cheapness) I had been considering doing exactly the very same thing. I've come up with two negatives. You'll have all of that fuel in your lap if theres ever a leak or accident. Gas is very heavy and mounting it up high like that won't do much for keeping the center of gravety low.

yeah but if it leaks it will soon be very low.........

just hope no one smokes!

Works okay on a 911 !

As I'm making a BEC I was considering using the space that the gearbox would have taken up, just need a 4" hole for the propshaft so plenty of room for an inverted 'L' shaped tank.
