I have a lead on a possible NICE motor. How can I identify a true Honda NICE? Would appreciate serial # ID, like I can do with the CT motors..I looked this over previously & it has that 3rd engine mount on the cylinder, but I didn't get really close or a chance to look it over....I have an opportunity this weekend & would like to look at while being better informed...I think there were some ATC motors that have that 3rd mount..
