I have had nothing but problems with this thing for the past year or so. I took it in to the shop twice since, only to get it home, let it sit a weak or two, and wont start. I'm getting a spark, everything seems clean, but when I checked the carb and fuel lines isnt gas supposed to come out of the line when not hooked to the carb? I dont know what to do!

I just checked the calendar, and all three dates hit on my dayshift that week. That means no matter what days i try, i hafta' burn 12 hrs.vacation each day to do it. Maybe I can make one day of it, or possibly two. But it looks like doing the whole 650 miles is `out' for me. don-ohio (:^(

i had that mechanic look at it, and he said that was what needed to be replaced, he said he did what you recommended checked the ground and made sure the points werent dirty, but he works on cars, not bikes is this not common to replace the coil on theese bikes?

I am thinking about buying a Raleigh motor bike with a tag on it saying motorbecane. Where can I find parts.
It looks to be built in Nottingham England in about the 60s.
Thanks

Can someone tell me exactly what I need to make my 2hp motor on a regular bicycle street legal?
Is a motorized bicycle different than a Moped?
I'm hearing many conflicting views from the CHP and DMV!
Anyway, I got the REG 230 form. That doesn't say anything about turn signals or brake lights. The bike just needs to be 2 wheeled, also human powered, 2HP, 30- mph.
I also know to wear the bicycle helmet and stay off pedestrian zones. I ready have a Class M1 motorcycle licence. etc.
What about resistration and insurance? Do I really need more than a headlight and tail iight?
Thanks!

My 82 urban express has been bogging out at full throttle, I think I've pretty much narrowed it down to running too rich. I've moved the carb slide needle to the different positions and it runs best with the needle in the lowest position (lean) but still has a hesitation/bog. My main jet size is 85, any suggestions on what size jet I should try? I did remove the baffles in the muffler if that would make a difference for jet size.
Posted on Feb 16, 2004, 5:43 PM from IP address 64.109.38.131
with 2 stroke engines, the carb flow and jetting has to be matched too the 'thru put'..
when an exhaust is made less restrictive ( removing baffles ) cutting pipe's etc..
more air is allowed / forced to move thru the engine..
depending on the carb opening, the air filter box, and the main jet..
the fuel mix either gets leaner or richer..
often you expect one thing and the opposite happens
it's a fuction of velocity ( air speed ) Vs volume..
more air without a speed change makes the mix lean and the jet will need to be bigger ( if you keep things that way )
faster air velocity means the air will draw more fuel thru the jet , making a richer mix..
tuned exhaust are designed to force a back pressure resonance way at specfic RPM ranges which acts to charge the cylinder/combustion chamber with more fuel mix
you said you are running rich and dropped the needle all the way down..
as a test... try this..
remove the airbox and foam filter..
and warm up the engine ( stay out of the dirt )
if you can adjust the carb so it runs better then you will need a less restrictive filter,
other wise you will need to change the exhaust or goto a smaller jet..
but samller jet means less fuel and less speed..which is why you moded the muffler to begin with..
also did you try bypassing/disconnecting the autochoke

i just cleaned out my carb today, its not bogging as bad at full throttle now, but i can still hear it. im looking for a bigger jet for my express sr. are the carbs close to the same on all the express? i may go check out bent bike here in washington. anyone tryed there for scooter stuff? i just heard about it, and apparently its very close to me!
Posted on Feb 16, 2004, 10:36 PM from IP address 65.102.115.65
look these bikes, set around for years, fuel and oil residue turn to varnish inside the engine, this hinders the intake of the fuel mix.. it also coats the cylinder wall and sticks the rings..
I never mod a carb or and engine untill I have put some miles on it, several hundred at least, and convinced that i have it cleaned out , loosen up, and running at it's best... then i will do the exhaust first, then a bore kit, then i will change carb jets if i need to.

how would i know if my ignition coil is bad? is this a common problem? it is a 77express with about 1200 miles on it, which hasnt been run in about 10years, i had a car mechanic look at it, and he said the spark plug isnt getting enough spark, so he said it needs a new igniton coil, and wires, has anyone had any past experience with this, and if so how much do theese parts run? thanks Mark
Posted on Feb 16, 2004, 1:31 PM from IP address 64.151.20.182
it's far more likely to be the points and condenser or even the spark plug..
the coil has a wire that grounds it to the frame.. make sure that wire and connection are good..
get someody with a tester/multimeter to make sure the engine the frame and the coil-ground all read continunity to each other..
under the chrome cover on the right side of the engine you will find the flywheel, behind the flywheel are the points and condenser..
lots of time the points get some corrosion from moisture from setting and are stuck or don't open all the way..
be easy on cleaning the points.. with these engines you set timing.. NOT point gap.. try to clean them with out loosing the screws and changing the setting.
if in doubt ,print this out and show it to somebody that can doit for you.
i think if you check these things you wil get your express running.

Hi, i know the maximum weight limit is only like 180lbs on a 78 honda express, but I've heard of many people weighing WELL over 180lbs, that still ride expresses, so I know it can hold more. So, my question: Is there a way I can make it into a 2 seater, somehow make the main seat longer, or add a seat on the rear rack, not that I would definetly do this, because it's not like theres anyone else I would want to ride around with me on my moped, but I'm just curious, it would be kind of cool to have 2 seats...

Hey guys, heard about the mod so I searched the board but I never found a straight how-to on performing it? ANyone know anything about it? I am gettin ancy to work on something . . hah
Also, are there any other mods for the spree that I could try?

I have a Honda Express (81 NA50) that ran great in the Summer, but now is having problems. It will start fine, but as the automatic choke allows the engine to slow, it will simply die. Any throttle application bogs the engine to point of stalling. I've thoroughly cleaned the carburator, replaced the fuel filter, fuel petcock, and gas cap. I've heated the muffler with a torch and tried to blow it out with compressed air, but I didn't get much debris. Any ideas?
Posted on Feb 15, 2004, 6:16 PM from IP address 24.21.1.50
unless the carb is running dry , the choke seems to be working..
it's possible your are running to lean, and need a little more gas when you open the throttle
have you tried adjusting the carb richer , after the motor warms and starts to bog..
also do a vaccum leak check, maybe the intake is sucking some air after things warm up and metal starts expanding..
also disconnect the hose from the choke to the carb and the intake '2 hoses' plug/cap the nipples on the carb and intake and try running that way.. do it after you warm up the motor and it wants to bog..you might have a leaking vaccum hose on the choke..

I have a 82 nu50m. I just bought it, it sat for several years. I cleaned the carb, gas tank and gas valve. It runs good up to about 3/4 throttle and starts bogging out. It also has a new spark plug. How does the auto choke work on these? could that be coming on? I also cleaned out the muffler, would it help to cut the muffler open and remove the baffles and reweld it shut?
Posted on Feb 12, 2004, 5:24 PM from IP address 64.109.38.131
.......checking to see if the airbox is clean and clear? If the air is restricted it will bog at higher rpms. Then try cleaning the muffler out in case it's plugging up with carbon.don-ohio

Thank you for resonding,
Yes I checked those things and cleaned both of then. How much fuel flow should come out of the line when diconnected from the carb? Or is there an adjustment for the oil injection pump? It seems to really smoke when its acting up. I have nice blue spark when I check it with the plug out, do these have breaker points that I could clean and adjust the gap? By the way it acts up I think I'm either running lean fuel or getting too much oil.
Posted on Feb 13, 2004, 4:37 AM from IP address 64.109.38.131
I wanna make sure first that this isn't an Iowa Express. They restricted them badly.
(1) To check fuel flow thru the carb,there should be a drain screw at the bottom of the float bowl to open and see if fuel runs freely. That means it's getting thru the needle valve. it won't run fast,but just steady.
(2)As far as I know there is no adjustment to the oil pump.
(3) No....electronic ignition.
(4) It's possible you're running lean because of a plugged vent in the fuel cap.One express I worked on had a fuel cap which would only vent if you didn't turn the handle on the gas cap all the way to the vent stop.
If it has an auto-choke, I guess it COULD be holding itself partially shut on you.An electric choke would need good voltage to it to open it probably. I'm not familiar with that set-up,but you can do a search of `Expressly Mopeds' here. The trick is when you get a desired result,you hit `cached' and it will highlight to the right place and results. don-ohio

Posted on Feb 13, 2004, 5:10 PM from IP address 12.109.127.66
the nu50 'urban express' has electronic ignition.. nothing can be adjusted
the oil pump has a control cable coming from the throttle , the max open postion can be changed a little.. BUT i doubt that you have any problem there..
it smokes after you get it it all warmed up..
then that is 'excess' oil in the crankcase or exhaust that is burning off..
use new injector oil in the oil tank.. NOT weedeatwer oil.. and keep riding, you will eventually get the system cleaned out..
you might need to remove the exhaust and flush with saftey solvent, and blow dry with compressed air.. then ride for an hour or two untill all the "now white' smoke goes away..
it's winter and unless you live in the southwest somewhere you are not likely to ride far enough and long enough to get the exhaust sytem and crankcase cleaned out , untill spring arrives.. it takes extended riding to get these bikes running like new after they have been alowed to set for years on end..
do not muck with the auto choke.. you wil only create more problems.. see my post about soaking carb spray in the hose's ( this page )
in the summer if you haveto/needto the choke can be bypassed.. but to not try to adjust it . open it or fuss with it.. you will end up making it unusable.

There is a little pointer on your oil pump at the engine. It should be pointing at a pin when the throttle is held full open. It's actually a little hard to see when the bike is all together. I agree with TMW, the type of oil you use can make a difference. I own 5 urban express' (they keep finding me) one acts sort of like yours in that I have to feather the throttle when wide open or the engine bogs a bit. It runs about 25 mph whereas my others will do 29 on a flat. I'm waiting for warm weather so I can get them out and swap carbs, mufflers etc to pin down what the problem is, but I'm pretty much convinced that a slightly larger main jet will solve it.

so i just saw that i have brown snow under my express...
dont worry i wasnt thinking about eating it
why is there oil leaking from the bottum of the sparkplug area where the heat sink fin thing attaches to the rest of the engine

the base gasket it saturated with oil..from the crankcase/intake
the gasket betwen the cylinder and head..
you can ride it as is or you can fixit.. this condition is messy but not harmfull
to fix.
you have too pull the cylinder and install a new gasket. you should remove excess oil from the crankcase while you have it open..
to prevent this from happening, change the brand of oil you are using.. to something that burns better and doesn't collect so much.. considering your cold climate you might want to switch to a pure synthetic oil.
besure NOT to over tighten/toruqe the head-cylinder bolts .. 10 ftlbs is honda's recomended MAX toruqe.
