I have an '85 Spree that seems to run OK. But, it won't even pull itself up a hill, with me WALKING beside it. I thought the clutch was bad, so I replaced it (with another used one, clutch and flywheel) and I get the same thing. After reading previous posts, I think it may be the belt, but the belt seems tight to me. How can you tell if it's bad? If it's tight, it should be OK, right?
Thanks

This will sound kinda crazy but try this if the moped idles but just doesnt have any powere. 1 st make sure the muffler isnt plugged. Have you had a non professional shop burn it out? I say non profesional because most authorized delaers will just sell you a new one. Anyway make sure that isnt the problem, you can usually remove the exhaust and see if it makes a difference right away.
2nd thing to check and I have seen it many many many times is a carbon build up in the exhaust port. This is the part that will sound crazy. As the age of the machine you also have build up of carbon. The carbon will actually form in the exhaust port and form almost a perfect cylinder wall shutting of the exhaust from getting out (Thats Bad) and causing low or now power. I have worked on many sprees and elite's that especially do this. You may be able to see the build up by taking the exhaust of but your best bet is to take the cylinder off and clean it with a pick, dremel or the best a porting tool. You should replace the gaskets but i have seen backyarders NOT and works fine for sometime.
Try this....MAYBE IT MIGHT HELP!

I live in Norway and the PA50's in Norway is different from the "wester'n" ones,but the engine is the same.
So what is the correct point gap (in .mm) on a Honda PA50 Camino?
Sorry my poor english,hope you will understand.
Best regards Bjorn

I have a 1980 peugeot 103 sp. it runs only at high speeds, I have to put the kickstand down and pedel very fast in order to get it to run, it seems to have good compression, I cleaned the carborater and it does spark but only runs at high speeds. any helpfull sugestions will be very much appreciated. thanks
Posted on Jun 10, 2004, 4:37 PM from IP address 67.72.98.56
Wow! Only runs at high speed? I wish I had that problem. My moped doesn't know what high speed is, unless you count 25 mph. Just kidding. The first thing to do is to work the throttle and see if anything moves on the carb. If not, it's just a stuck cable.

should a buy a nc 50 parting out to use for parts on my nx50m? would the muffler line up? what other parts might switch over easy? the nc apparently has a cut wire harness...
both 1982 bikes.

they don't have a belt, it's a totally different tranny
the NC exhaust has a tighter bend coming around the engine case becuase it doesn't have a starter ( it won't clear your starter ) so it's not usable on your scoot

I bought a used 1978 Honda Express (NC50) and found out the lower portion of the carb(float bowl??) is cracked in several places. Do you have any carb parts??? PA08BAPI

I posted this over at Moped Army as well and thought I might try for some help here also.I am helping our boys friend get his 80 NC 50 going. We had to get another motor (from E-bay) and got it together. Anyways to make it short as possible the bike runs ok, but actually runs better when you open the throttle 3/4 (around 25 mph) and when you open it up full throttle it SLOWS DOWN to 17-18 mph. The cylinder and piston/rings are in good shape and I put new base and head gasket on it, cleaned the carb, has a new plug and air cleaner.
Thanks

If I had to guess I would say that your bike's muffler has become clogged.
It might be worth removing the muffler long enough to see if it continues to accelerate as you turn the throttle.
If thats the case, I'm sure someone else here can suggest how to clear out the muffler.
Posted on Jun 10, 2004, 3:44 AM from IP address 154.20.89.136
one more thing I forgot to suggest, it wouldnt hurt to pull off your air filter cover and make sure the filter is both clean and in good shape. They like to fall apart after 20 years.
Any place that deals with small engines can sell you a new foam thing that will fit it for a reasonable price if needed.
Posted on Jun 11, 2004, 8:46 PM from IP address 154.20.89.136
I don't think it is a Iowa model. I was thinking of putting the muffler in a temper here at work (I work at a heat treat) at around 1100 degrees F. for a couple hours then blow it out.

I have a 1981 NC50 that was given to me. It runs good but the turn signals won't flash. The bulbs light up dimly and the headlight dims when you turn them on. Is it a bad flasher? Bad battery? Would like someone's help on this. Thanks!
Posted on Jun 8, 2004, 2:22 PM from IP address 12.217.16.4
the bulbs are the original. The battery has some age and when I got it out for the season I had charged the battery. But I'll check the battery again. Thanks!
Posted on Jun 9, 2004, 6:04 PM from IP address 12.217.16.4
You can get a new battery from J.C Whitney for $8 plus shipping.
It is important because if you keep trying to start it with a bad battery, it will burn out your headlight and other bulbs. And headlights are expensive. $30.
And remember if you replace smaller
bulbs, turn signal etc, they are 6 volt.
Good luck.

Does anyone on the forum know where to purchase a new belt for an express sr? Honda no longer offers a replacement belt. Seems like the NU 50 should be the same, but it has a different part number.
Posted on Jun 8, 2004, 1:31 PM from IP address 207.191.236.63
The Honda belt, part number 23100-187-003 or 23100-187-004, is no longer available, nor does Honda plan to re-order it. Honda WILL NOT furnish the specifications for this belt to make it easier to find a replacement. The belt was manufactured by Mitsuboshi and they WILL NOT furnish the original specs for the belt to make it easier to find a replacement. It appears tht no after market manufacturer has interest in making a belt for this scooter either. The belt is the most important factor in scooter performance and operation. For example, Honda recommends replacement of the belt when it wears to 13 mm. New, it is only 14 mm, so there is no tolerance for wear. For each mm of wear, top speed decreases by 3 to 5 mph. While an industrial or even automotive "similar" belt might be found, it WILL be different in width, taper, rigidity, and perhaps the overall diameter. So, it is rather worthless to try to use one of these "similar" replacements and ever expect the scooter to have any sort of like new performance. Honda's attitude is that they have fulfilled their requirement to furnish the part as long as mndated, and now all you Honda Nx50M owners can throw that junk in the scrap pile or put on a "similar" belt that might get you 20 - 25 mph if you are lucky. Seems, the NX50M is now a sort of dinosaur. If anyone has different information, p;ease let us know.

I am looking for an inexpensive airbreather assembly for a honda urban express NU50 which is different than the NA and NC 50 express. I believe an urban express deluxe NU50M would work both '82 or '83. Thanks.

Does anyone know of a ready source for a carb kit for a '78 NC50? I ordered one advertised as being for the NC50 from ebay. Upon arrival (from Canada) I find that it's really for a NU50. Entirely different carb-the only thing useful from the kit was the carb to intake O-ring.
My real problem is that the needle and seat are worn which causes the float to occasionally stick open. When I got the 'ped the needle had a hanger on it which I just tried getting ride of because the shop manual makes no picture of it. The short and long is that it makes no difference if the hanger is there or not-if the float falls far enough the needle will cock itself sideways in a bind and not close. Is this carb needle supposed to have a hanger on it?
Another thing, the bowl has a small rubber plug in it that plugs up the bottom of the main jet. When the bottom is plugged, the fuel flows into the jet through three small holes on the side of the jet. If the plug is gone or not sealing up will this cause richening? Is this there as a restriction or is it another attempt at keeping sediment out of the jet (just like the petcock tube)?
All advice is appreciated.
Thanks

Hello I just purchased a very used 1980 honda express with the nc 50 engine. I am tring to find out if I have a bad gas/oil tank or not. I cleaned it out and added gas in the gas spout and same with the oil and I checked back a few days later and happened to notice that the gas is getting in the oil side and the same with the gas side. Is this normal because it doesnt make sence to me. because you have the oil injecter that puts the oil into the carb. Just note that I havent been able to try to start it yet because I the starter assembly came to me in pieces with a broken spring that I have to replace and have been having a hard time tring to find one and Also I have to trace out the electrical because of no spark. Thanks

There must be a crack between your 2 tanks you should not be getting different fluid in the seperate tanks. We may have a GOOD clean tank depending on the color. We also have used starter springs and covers for your model. you can email us at dealeroverstock@sbcglobal.net if you are needing parts.
Posted on Jun 7, 2004, 7:55 AM from IP address 68.23.76.230
This is not normal. Sounds like you have a small hole located between the gas and oil tanks. This is caused by rust. Either replace the tank or just mix the gas and oil directly 25:1. That's the safest anyway. Make sure there is no rust in the tank. This can cause havic on the carb.

I've got a new 67 cc big bore in my honda elite 1987. Last big bore kit I had ran into low compression after 500 miles. This kit overheated once when I was running too little oil in my premix. I'm now running between 25:1 and 30:1. I bought a non-contact infrared temperature gauge, and am wondering what I should be reading on the gauge. I imagine a difference in just 100 degrees could make a big difference. After a 5 minute ride the max temperature was 520 degrees F on the exhaust pipes, which is the most convenient place to measure. It's hard to aim at the exhaust port on the cylinder, because I get readings from the exhaust pipes.
If anyone can offer numbers that I should be reading, or numbers that I definitely should not see, that will help me tell if I'm running too hot or not.
Thanks,
Nate
