I believe the 46 is a pretty old motor, I had one in 88, crashed it and spent over 100$ in parts to fix it. I guess it shows you how much I liked it. It was a very well made dependable motor. I currently have 2-91's and a 120r by enya, all good runners. Enya supposedly uses the best metals and it was not unheard of to see a 30 year old 2 stroke still running. Ive had a few os max's, never owned a saito and dont think I will, the only thing I like better than enya is YS motors. YS is definetly the cream of the crop.
