I am going with a brand new motor to replace my 2005 Blue head. Since January 1 of this year I have put 67 hours on it. But, it is original, it has not been overhauled. It has 71 hours at this time. I am selling it with carbs and exhaust, no gearbox, electric start or cooling system. Carbs will have stock jetting put in them before it sells. It is still in operation at this time and will likely get a couple more hours on it before the new one gets here. It is in western colorado near glenwood springs. It is in a CGS Hawk.
Not sure what value it has.
