I don't see any screws, under it, but I do see three brass type of punch marks under it. I just need to pop those out somehow? I still might buy an ignition switch though since I would prefer to have the ignition work the normal way but maybe I will just remove the tumblers
Currently have an NU50 moped that has an ignition but no keys. I was going to get my ignition lock switch rekeyed by a locksmith, but I'm assuming that will cost a bit much. I also didn't see any key code anywhere on the lock that I could just order online. So I searched on mopedarmy and found a few suggestions, but one poster said he believed an MB5 had the same ignition switch as t
Absolutely! When it's running I'll send you a video for sure. You saved me tons of hours of work! Thank you!
Oh my gosh!! Jack, you are a frickin life saver! It was the battery connection!!! As I mentioned earlier, I have one NU50M and two NU50 mopeds. I never even had a battery connected at all since my NU50M gets spark without a battery connection so I assumed the NU50 was the same. Not to mention all those stories I hear of people blowing out bulbs running their Urban Express mopeds without batte
Ok perfect! Thank you for the clarification PD, now I have at least one less thing to worry about
Interesting, are you sure? If so, then something weird is going on. I currently have one NU50M and two NU50 mopeds. All of them have issues but one of the NU50 mopeds does run. All of my ignition switches have 6 prongs and their corresponding receptacles all have 6 spots for the prongs. In the photos below I've attached what they look like. Two of the ignition switches are on the white
Okay, I swapped out the CDI too. Still no spark. You think I should swap out the ignition coil now?
Okay thanks, I'll swap out the CDI unit right now. I believe it is right under the seat in the Urban Express, right?
Thank you for the advice, this is all helpful to me since I have no knowledge on anything with electrical stuff. I have an NU50M that is running so I have been using that to kind of take parts and test it on the NU50 that I have that doesn't have spark. I was kind of in a rush today and wanted to start testing some parts so I did a few minor things. This is what I've done so far:1) B
Okay, thank you very much. Much appreciated! The only things I have done so far is I just put a brand new spark plug in it and I already started to swap out the kill switch because it actually felt a bit funky when I used the switch, like something isn't clicking right so I thought that may be the issue. But I will use your advice and check everything you mentioned. Will probably take qu
Have a Honda Urban Express with no spark. Luckily I also have another Urban Express that is working so I can swap parts from the moped with good spark to the moped with no spark to check where the problem is. I've seen the main things to check by looking at the shop manual, but was wondering if anyone had an opinion on the order of "most likely to be the problem to least likely to be t
I agree, I wouldn't want to run more than one tank like that through it. Having a tank of premix in there will give me some time to see if the oil injection system is working properly too, since this moped has not been run in years and at least now I can check to see if the injection system is operational. As of now it seems to be working, but I'll have to check the oil levels in the o
I had to do it, I really wanted to try out my premix idea so I thought I'd give it a shot first. I realized the previous owner had installed an improperly fitting oil inlet line, so I replaced that with a clear oil line and while doing that I also checked the port on the oil pump and the port had oil in it so I'm assuming the oil pump was full. I then installed the new clear oil inlet
Ok, I will try out your method to see how it goes. Definitely seems easier than the method in the manual. One question though, when you say to "lightly pressurize the oil tank," do you mean to fill the oil tank with oil? Or are you referring to pressurizing the oil tank in some other way?
Thanks for the reply, that makes more sense to me. An oil pump may not have the specific tolerances to pump air bubbles out, but can obviously pump oil since that is what it was made for. Good point. You mentioned that there is a bleeder on the oil pump. I did not originally see a bleeder anywhere in the manual when I did the process the first time. I looked at the manual again and I realize
Sure, I understand that doing it the way the manual states will work great. I'm just trying to understand for my own knowledge if using my other method has any downsides or not. I can't think of anything for certain, besides getting a bit more oil in the moped for about 100 miles since I'd have premix going through it with some of the oil injection system till it pumps out all the
The last time I bled the oil injection system in a Honda Urban Express, I did it the way the manual stated. It wasn't hard but it was messy. I have another Urban Express that is going to need to be bled too since it was sitting for years without any oil in the system at all. The tank and the oil lines were totally dry, so I was thinking... to bleed the oil injection system couldn't yo
Okay thanks, I will try that out then. To answer your question, I received 3 mopeds from the seller, but they are missing parts and one appears to have engine damage. So I'm thinking I may only get 1 or 2 running with the parts I currently have between the 3 mopeds, and I'm guessing I will have to buy several parts for the last bike to get it running. Lots to do lol
Do you really have to pull in both brake levers to get spark when trying to start the Urban Express moped? I don't remember if I've had a moped like that before, so that would be interesting. Also, why does it matter if the tail light bulb is blown or not? Just trying to understand a bit, that's all. Thanks
Okay, thank you very much. I appreciate your response. I will try out everything you suggested to see if I can get a spark. Glad to hear you're working on the same thing. Hopefully we both can get our mopeds to get spark so we can get them back to running condition. Such a rewarding feeling when you finally get them running again.
Here are a few other photos:
Picked up a few Honda Urban Express mopeds that were in rough condition from someone several years ago and am finally getting around to working on them. All of the mopeds had been worked on by the previous owner and he never was able to get them running. They had some parts missing. The first one I am trying to tackle is the one in the photos that didn't have many parts missing but had be
Okay, thanks for the replies everyone. Seems that some people on here think I should keep the oil injection system and some think I should delete it. For now, I guess I'll keep it and try to go through the oil system to make sure it is working. Random question, but the moped has oil in the oil tank already from the previous owner. The oil has been in there for several years (no clue how o
Okay, thank you for the response. I'll leave the oil injection system intact then if you think it is reliable. The tank does have oil in it, the oil lines are all really dark from the oil sitting in them all these years so it's hard to look for air bubbles in them. Is there any way to check to see if the pump is working prior to firing up the engine? I don't want to start the en
Got a moped that I've not had time to work on up until recently. This one I purchased in non-running condition and am planning to clean the carb, get new spark plugs, clean the air filter, and see if it fires up. I've never actually seen it running. I was unsure if I should disable the oil pump on it and just run pre-mix. How reliable are the oil delivery systems on the Honda Urban E
yeah, I am going to get a motorcycle eventually but want to screw around with modding a ped first. Yeah, the 50mph is the easy part to me, I was more concerned about getting the 44mph on hills since I don't think I've seen anyone on the forum say that they could do that. I am going to try anyways, it just seems too fun not to:)
Was thinking of buying a moped simply to mod, but I really want it to go at least 44 or 45 mph on hills, and at least 48 to 50mph on flats without spending more than 300 dollars on the mods. Is that even possible?I kind of want to do it on a top tank moped, like a Tomos Targa LX. I know it is very possible to hit 50mph on flats, but I want something that can climb average hills at about 44 mph.
Oh, I never knew that puch maxis could come restricted. I'll have to take a look at his exhaust then. Thanks for the info:)
Cool, thanks for the info bud, I appreciate it. I guess I'll tell him to look into getting a performance exhaust, thanks a bunch!
Ok, I helped a friend get his Puch Maxi running again. He said he heard these things had governors on them. Is this true?If so, how to I de-restrict it and let it run faster without buying performance upgrades? I know some scooters (not mopeds) have bolts in their exhaust that you simply take out to increase exhaust flow and gain speed. I didn't know if a 2HP Puch Maxi does too. He just
