As some of you know, I am building a liquid-cooled blaster(see my sig). I am in the process of modifying the frame to accomidate a radiator. I have a set of 250r trike radiators, but I don't think I'll be able to use them.
What is the smallest size radiator that would have the ability to cool this thing? Has anyone fit a radiator in their blaster for other motor swaps? If so, what did you use and where did you put it?

I was thinking of using the trike's radiators and mounting them in front of the bars like a banshee, but then I'd have to make a custom hood/shroud.

What do any of you think??
