Bob my back up motor is an 2004 kawasaki I have owned it since 2004 and never had the head of of it I ran it for 4 years very hard. I took it off because the 2008 had a more advanced design. It cost me $1900.00 on ebay. If it blows I'll buy another and put it on. I'm a tinker by heart I built my own injection and test on an old 30 year old clayton Dyno. I can't tell you how much hp is there but I can tell you that my a/f ratio is spot on and I'm not going to fill my crank case with un used alky. If you get a chance try to make one our races I would like to talk to you in person. I still think your cars are neat even if you run on those big old tires now. It isn't any fun fighting amongst our self maybe get some outside agitators in to get people thinking.
