racer8432955,

I run a GSXR1000 on gas. I have a Henchcraft with a 1/2 hood and I use a Radiator and Fan that has the most surface area that would fit in a Henchcraft (from Larry at Speedpartz). For coolant, I also use Water Wetter and distilled water. The only thing I have in front of my radiator is a piece of Honeycomb and perforated steel with staggered .25" holes - 58% open (from McMaster-Carr). -also, make sure you have holes in top of your hood or some other way for the air to get out or you might as well block your radiator off!

I hope this info is helpful,
Doug Norrie
