Ok I just purchased this 1987 Motomarina Raven today for 75.00. It is a non-runner. But I am trying everything to get it running again. It has gas, compression, but no spark. It has a brand new coil on it. I have posted some pictures for you guys so you know what i mean. There are three gray wires also not grounded but i don't know what they are for. So could you guys help me that now motomaina's better than I do. Also could you tell me a little info on this bike and the motor since i am new to this brand.
