Anyone run across a good source for comparison of engine specs for the usual candidates for engines we see on current ZTRs? The gasoline engines would be in the 20-35hp range, and the specs would optimally show hp, torque, cooling configuration, shaft orientation, model number, and some meaningful measure of fuel consumption per hr. Diesel specs would be appreciated too. I have looked, and find the specs hard to find and incomplete. Surely some nice outfit has put it all together in a spread sheet, or, in the alternative, someone can cite URLs that give separate specs for each manufacturer (gas: Kawasaki, Kohler, Vanguard; Diesel: Kubota, Caterpiller, Generac, Daihatsu, Yanmar), so I can do it myself.
