The Simplex was made in New Orleans and then in Boston and somewhere in California. The engine in this one is not original. The engine is an REO made in Lansing, Michigan. One evening the bike was giving me that look so I decided to try and get it running. First thing I checked was spark. No spark. I had to get the flywheel off to check out the ignition and that was a bit of fun. Anyway all I did was clean and adjust the points and I had good spark again. Next up was the carb. Got that out of the way and added some fresh oil. I asked my 8 year old son if he thought it would run. He said the only way this thing is going to run is if you start over with a new motorcycle. Anyway I pulled it over 3 times and it was running. It even idled nicely. I really want to ride this one but I think its going to need some new belts and more attention before that happens.
