"I am selling this 1977 honda express moped scooter. It is legal to drive on the road. It will get up to 28 miles per hour. It is in great condition. I also have the hauler that was made to haul this behind a car or something. It has a little over 800 miles. I also have a Motobacne scooter but it is not running it needs a petcock and a tire. I am asking $300 for it. It is the blue scooter in the picture. Cash Only and serious inquires only please. The price is negotiable. If you have any questions you can email or call 252-572-4416 and ask for Mickey THanks"You can find the craigslist posting here: http://raleigh.craigslist.org/mcy/1500513537.html
So, if you have inspected the things listed above you should find that your 1978 Honda Express nc 50 moped's top speed is 25-30 MPH. Under optimal conditions you should be crusing at 30 mph with good fuel and oil. Although, the 1978 nc50 was designed for a normal max speed of 25 mph (according to manual documentation).
You can always INCREASE your Honda Express moped's top speed by "Performance Tuning" it. I will go into further detail in the weeks to come about how to and where to buy parts for performance turning your Honda Express II, Honda Express SR and Honda Urban Express moped.
The previous owner had failed to re-install it. Yikes! That might contribute to why I have been having back-firing problems with the moped at top speeds. I realize the 1978 Honda nc 50 foam air filter needs to be soaked and then lightly rung before being place on the moped. The saturation of the oil in the foam air cleaner helps to provide the proper mixture of oil/air.
So, began my search online to find new cheap Honda Express Moped parts that would list the foam air filter part. I shortly discovered the Honda part #:
OEM#: 17205-147-000
Found picture of part on http://www.cmsnl.com/:
Was able to find the part on BikeBandit.com part shows up on search result page for Honda Express Element Air Cleaner. It looks like I would pay $11.78 for part with shipping.
I first called local PepBoys Automotive to see if they had some performance foam filter material I could make my own filter from. The guy wasn't very helpful and just said... "No." I also tried calling a local motor bike shop and they told me they could get honda express nc50 foam performance air filter material by the sheet. They didn't have any in stock but they could order it for $10.
I went with Bike Bandit's moped parts and paid the $11.78 for part w/ shipping.
"Just bought a 1981 NC50 about a week ago. It starts right up and runs great. However, gas keeps running out of a small tube underneath the engine, in front of the kickstand. I first noticed it when I turned off the engine after riding it. It stops if I turn off the fuel valve. Is this normal? If not, how do I fix it?"After reading several of the posts, it seems that I might need a new express carburetor float, float pin, or mounting screw. I will have to open up the Honda NC50 carb to tell. I also need to find out where to purchase these parts... cheaply! You can get a set of all these for the rip-off price of $60 with shipping on Ebay... OUCH!
"So, I was dumb and didn't know that the cylinder thingy had grooves on it so your advice helped me, I just pulled it out, I was lucky I didn't damage it. The original problem was that I was leaking gas out of the carb. The needle wasn't closing off the seat. The pin that holds the float was bent so when it would sit one way it wouldn't push the float up to close the seat. We fixed it for a day because we just happened to put the pin in so that it laid well enough to close off the seat. We straightened out the pin and now it closes off that seat. It was frustrating taking that carb apart 10 times. Each time we thought we fixed it then wed get it all back together, turn her on and it would just pour gas out. Glad its fixed."

"I have tried the honda express headlight repair and i don't recommend it. while it is true that you can swap bulbs, you must first remove the old bulb, cut out some of the sheet metal so the new bulb will fit through, and then put in the new bulb the problem i have found is that the original bulb is much taller than any replacement bulbs i have have found, and that severely affects the focus of the light. the original bulb is tall so that the light source sits and the "focal point" of the convex reflective surface, which means that the headlight beam is in the proper focus. when you put in a shorter aftermarlet bulb, it does not sit a the correct position (the focal point) and thus the headlight beam is not at all focussed and you get this very wide beam that spreads out all over the place but is not very bright. you don't need a large, spread out beam - you need a small focussed one that is bright. for that reason, i have decided to cough up the $ and buy the factory headlight."
