It sounds like your carbs are gummed up you can try running it with some High octane fule and spraying some carb cleaner into the intakes and see if that clears it up, or take off the carbs and clean them with the carb cleaner, you also may check to see if your running to lean (not enough fuel) as when the choke is on you are restricting air flow to give more fuel and less air i am willing to bet if you run the carb cleaner through it you may be allright, you may want to change the oil and filter for safety sakes as well

1999 Honda Aero 1100c3. sat for two years with fuel in tank,carbs, etc. drained tank and carbs and cleaned, then reassembled. Bike will fire and instantly stall. Did have it running a month ago, but


remove carbs and rebuild completely, old fuel builds shellac in needle valves and other ports. clean float valves thoroughly, and check choke for proper operation

Any chance there was any old fuel left in the tank when you started messing with it. Most fuels have ethanol blended into them. After about 2 months ethanol blended fuels go through a phase separation... meaning the ethanol separates from the fuel and starts eating it's way through just about anything made out of rubber. I had an old work chainsaw that sat with a tank full of fuel for about 2 years. When I picked it up the fuel filter was rattling around inside the tank ... the hose had completely dissolved. The short section of fuel line between the tank and carb was like putty. In your case, I would want to make sure all the old fuel was drained out of the lines before tearing into anything else.

Hi Roy ,

Your bike has been sitting in storage and the fuel is too old ad is stale by now .
Re open the carby , clean it properly with new fuel , all the jets need to be inspected for dirt or residue left by the old fuel , drain all the fuel out of the tank and replace it by new fuel .
The old fuel leaves a deposit film which needs to be clean so the best way is to pour a little fuel into your tank , shake the tank to clean it and drain it again .
Make sure that all gasket in the carby are clean or new as extra air intake will make the bike run rough .
Try all this and you will see that the bike will run better .

drain old fuel first and replace with fresh,then check fuel filter,carbs need to be cleaned after sitting so long, yes there should be a constant flow of fuel

Starting problems


Check the compression. If it has low compression it will always be difficult to start. I have the same bike. It is a really good starter, comparatively to other older 'cycles I own. 1) Check the fuel level in the tank, and be sure to turn the fuel switch (left side of bike below tank and seat) to On, or even Reserve 2) In stock tuning, my bike likes full choke for cold start, in any ambient temperature, it likes to warm up with the choke on, until it starts to sputter from the rich mixture. 3) I believe this bike has vacuume tube that goes to the fuel petcock, this shuts off fuel to carbs when bike is not running. Thus if the bike has not run in a while, or the carbs drained, it will take several start attempts to get the carb float bowls filled. 4) This bike is hard to start if the battery is old or marginally charged. 5) Also pull the spark plugs, if they are brown, or black, change them. 6) check the air cleaner, if it is too dirty it will essentially act like a choke
