Question about 1982 Honda CX 500 B

1 Answer

I have a 1984 500CX that sat all winter and the gas got real stale- smelled bad; so I drained it and put in fresh gas. It started right up but when I went for a test ride it has almost no power and can hardly get it up to speed to get into second. If I do put it into second gear it almost stalls out from lack of power. Do I have water in the gas?

    Thanks, would I get a similar result if I use a carb cleaner that you add to the gas?

No, most likely you have a blocked jet. If you have the expertise, strip the carbs and clean them out, if not, taking the carbs off and sending them to a carb rebuild company is less than $100 each, plus they will renew all the old parts (seals, jets, etc.) and your bike will run like new!

    Most likely not - carb cleaner like red-ex that you put in the gas is for 'keeping' you carb clean - it doesn't usually do a good job of cleaning out blockages. But you can buy carb cleaner in a spray can that will! It is made up of trichlorethane which you should also be able to buy in liquid form for soaking.

    I would spray your carb heavily, then strip your carb of all its jets and soak them overnight. If you have access to a high pressure air source, that will dislodge mst crud once you have finished soaking - but I would definitely buy a rebuild kit as your seals and gaskets have likely gone hard with such a long period of no use.

Will gas that's left in a gas tank over the winter keep my motorcycle from starting

If its stale possibly. If its carbureted and the stale gas has sat all winter with no stablilizer- quite likely the carb passages maybe gummed up and blocked- seen this myself..Drain old gas and refill. if fuel injected there may be another issue it should at least fire if the fuel is getting to cylinders and theres a spark.. if a Carb.. the same.. so if carb and no fir or no smell of fuel from exhaust- carb passages clogged or petcock..

Saw will start. runs a little sluggish at first. then it will smooth out and rev high and run strong for a few minutes then gets sluggish again and dies. will not start again for 5 to 7 minutes minimum....

Being springtime, I'm thinking you may have had your saw sitting all winter with last years gas in it. If so, you'll need to clean the carburator and spark plug real good, then put fresh gas in it. Always remember to run your saw out of gas before putting it away. Gas only stays fresh for a few weeks and will foul up your sparkplug as well as plug up the inside of your carb when it gets stale.

Will not start -changed plugs bike has been on battery tnder all winter added dry gas battery seem fine but still will not start.don't know what to do next.

Your fuel will go stale after a month or so.
You need to drain your tank and put fresh fuel in.
Also put some seafoam (if in US) or forte fuel conditioner in tank as old fuel coats the inside of fuel system and can cause it to stick.
let me know how you get on.

Hi, I purchased the above snow thrower new in Nov 2009. Unfortunately, we had the driest winter on record up here in Toronto that 2009-2010 winter season. Beside testing to see if the engine started,...

Try draining the float bowl on the carburetor so that fresh fuel will flow in. Also, spray carburetor cleaner into the jets to remove any varnish from them. Add some fuel system cleaner to the tank so that when running, the cleaner will improve carburetor function. Hope this avoids a complete carburetor tear-down and clean!

Back fires and rough engine

Drain your fuel tank first. Then mix 50/50 parts mixing oil and fresh gas. Put fresh gas into the saw as well as putting in a new spark plug and start it up. Stale gas (gas that has sat in the tank or gas jug for an extended period of time), bad gas or water in the gas will cause it to rough idle and back fire.

'07 Triumph Bonneville idles but wont accelerate

What happens when you try to accelerate?

Does the exhaust smell 'weird' when it's idling?

The most likely problem, especially with the bike sitting up during summer, would be gas has gone stale. If the bike sits long enough, the gas will actually turn into a varnish.

Drain the tank, refill with fresh gas, and let it run a while.
Basically, you have to run out whatever gas is between the tank and the cylinders, so the fresh gas can get to the cylinders.

I'd put a box fan blowing on the front of the bike to help keep the ehat down. Blip the throttle after a few inutes. Depending onhow much old gas is 'stored' in the fuel lines and such, it may take 10 or 20 minutes to burn out the old gas. Keep blipping every few minutes, and let it cool down after 20 minutes. Some bikes have short fuel path and clear in 2 minutes at idle, I've seen custom setups that took over an hour.

My 81 Honda gl 1100 was not winterized. Installed new battery. Cranking fine. Wants to start. Smell gas, probably flooded.

You should drain your gas, gas line, and carbs.
Try putting in some fresh gas and see if it wil fire up.
If not a carb rebuild is more than likely going to be needed.
