Hi all. Been offline for a while, up in extreme northern NH where there is no cell coverage worth mentioning.
Good news. The $12.95 eBay ignition coil fixed the Urban Express right up. It's running really well. After almost 2 months of tinkering, I think it's done. I registered it for road use yesterday and am having a blast riding it.
Thank you all for your assistance. I've put almost $400 worth of parts and a lot of time into this Urban Express and I am pleased with the results. I've resurrected many an old Honda however they were all in the 350cc and up four-stroke category. This little bike is very cool. Everywhere I go, people want to ask about it. It is a true conversation starter. I can't wait to rip around Market Square in Portsmouth, NH. There's quite a moped renaissance happening there.
Now that the NU50 is on the road, here are my two red Hondas at home in the garage. Thanks again for all your help.
