I bought the 212 harbor freight predator motor for $99. Traded my original motor to Wayne for the mounting plate, the jack shaft, the comet clutch and and kicker. I think about $800 worth of parts if you were to buy them out right from Wayne, but you don't need the kicker, you can use the pull start, and get the kicker later if you wanted, Worked on it two nights after work mounting everything and had it started and running. Still need to make a few adjustments to the jack shaft b/c it wants to slip a little when I get on it from a dead stop, but it runs at least twice as fast as the original motor. I haven't tested it for top speed, b/c I only have 26" bicycle tires on it. Starts with one kick every time...(that's only if you remember to switch the kill switch to the run position.) I have very little mechanical ability and was able to do all of it in just 2 evenings. Some on here like the upright motors better b/c they look more original. I also like the looks, but it takes more fabrication to get them mounted. Look at some of the posts in this section to see which one you prefer, and decide how much work you want to do. I love the look of the original motor, but changing to the clone motor was the best decision I have made for what I am wanting to do with my simplex. Carryall is a good one to talk to about these motors and is very willing to help out,
