[Resolved]  Honda Unicorn — Honda unicorn

I have a problem with my Honda unicorn the bike. The bike starts but the moment I accelerate the engine stops. In the rainy season, this gets worst. Some time during travel if I change the gears the moment I leave the clutch the engine stops and jump-starts. The service center does not seem to have an answer to the problem.
I have tried changing the spark plug, cleaning the tank, cleaning the carburetor, changing the diaphragm in the carburetor. Engine de-carb. Nothing seams to work. The worst thing is the problem is not consistent. Does not happen all the time, which makes me look like a fool at the service center.

Can any one advice.

Dear Russel

There could be a lot of problems with the engine getting shut off...
1. Sometimes the petrol tank forms a vaccum within itself and it shuts off fuel supply to the carburretor. normally this doesnt happen in motorcycles with a fuel injected system..it happens more or less in all carburretor type engines...All you need to do is keep the fuel tank opened for a while(say for a few seconds) or try blowing in air inside the petrol tank...so as to feed some air inside the tank...

2. If you keep your fuel valve opened all the time it could sometimes overflow the head of the engine which sometimes results to a flooded engine...in such cases..shut off the fuel valve and try to start the engine using the kick lever(not the Elecric starter).

3.After getting the bike water washed do make sure the spark plug cables are dry and not wet...wet cables wont be able to generate enough power to power your engine...

4. if none of the cases work..then it could be some problems with the power supply( the magneto cables which provides power to the spark plug are not able to generate enough power)..such cases dont happen very often though...

Due follow these steps i am sure your honda unicorn will run like a dream
i had bought honda unicorn in nov 2008 and its been a long time i am getting a problem that my bike gives lot of jerks it almost stops then when i keep the choke on then only the engine starts, when to authorised service centre in mumbai mahim at sai honda but even they have not yet solved it..
hi Russell,

I'm also facing the problem. And this is my bike's first winter and u cannot imagine my biking experience is like hell with this so called Wing Rider. After 3 complaints and visiting service centers again and again nothing seems to work. I think we have to live with it and it seems to be some design flaw in this Japanese Bike.
I'll request you to not to recommend this bike to anyone...
The problem seems to be with the Carburetor diaphragm whick gets wornout every 6 months. So the only solution i found is to change Carburetor diaphragm as it does not cost a lot.

Thanks,
Russell Pinheiro
