Here is my problem. I can get a little work done to my 1985 200s motor and it will be good to go. My 1984 200es big red i have has a motor that is trash. The es is shaft driven while the s is chain driven. Is there any way i could use the s motor on the es trike? I really want the es to be my main trike since it has reverse and all. Any ideas or am i just dreaming
