Bike's been sitting most of the summer. Have no acceleration or power.

Bike's been sitting most of the summer. Now starts and idle fine once hot (with choke on). Have no acceleration or power. Can get up to maybe 60, struggles going up hills. Do you think this is the fuel filter or a carb issue?

SOURCE: Yamaha 06' V-star 650 idle prolbem!

Fuel filter is located near the fuel shutoff valve within three inches. It is inline between the shutoff valve and the fuel pump (towards tank).

The fuel circuit is: Tank/Fuel Pump/Fuel Filter/Fuel Shut-off Valve/Carbs.

You first step is to check for fuel delivery to the filter. Make sure the bike is cool and no iginition sources are nearby. Disconnect the inlet line at the filter and turn key on and crank engine (to trigger fuel pump.) Do not try and start at this time (choke off).

If fuel is adequate to the filter, check the filter by blowing through it, it should easily pass air. Replace filter if questionable.

Next reconnect the fuel lines and remove float bowl drain plugs in the back of the carbs (2 per carb). If with key on and cranking fuel pours out of these ports then you probably have clogged fuel jets. If not then the float bowl needles / pipes could be plugged with varnish from dried fuel. You can try spraying carb cleaner into the fuel inlet to clear the varnish and then retest. Careful not to spray carb cleaner on yourself (wrap straw with a rag).

If you have good fuel flow to the carbs and bowls you probably have varnish plugging the jets. You should remove the carbs and clean them thoroughly.

Hope this helps,

Kal

SOURCE: Won't idle without choke

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

SOURCE: Yamaha TTR 125 L won't idle

i cleaned the carb on the bike and put it back together and now it is as if the float is stuck open and is just dumping gas out of the carb all over the ground.

sounds major. Clanking and low on oil sounds like a broken piston ring. Suggest dealer check with compression tester rear cylinder. Replace v star with Harley if necessary.

Bike will start but stops after a second or two

If it was used "once or twice all summer", and you left the ga in it, the carbs are probably gummed/clogged up.
When gas sits, it's components start to separate, and it turns almost into a varnish.
This starts clogging up the jets and ports in the carb.

You probably need to "boil out" the carbs

Bike starts and idles with no problem but when I accelerate it dies

Hey Kenneth,
Sounds like the carburetor needs a Qualified Professional to clean and set it.. check the compression, it should be >120PSI., if not..fix it..
once you HAVE done this... it should run fine...

In park the engine dies; only will run if given gas

It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.

'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.

We have a 90 Quattro V8. Last summer I changed

Your V8 Audi has two necessary sensors that malfunction due to their placement in extreme heat on the lower left side of the engine just inside of the header/down pipe connection. They read the flywheel position for the engines computer ECU. The reference sensor is always suspect, but the speed sensor may need to be changed, as well. The wire connectors to the sensors that sit above the FL suspension can be tested, or just replace both sensors to get some quality time with your V8.

The 2000 mountianeer starts and runs fine but shuts off

CHECK THE COLD START ENRICHMENT VALVE AND OR THE IDLE CONTROL VALVE. I AM ASSUMING THAT YOUR VEHICLE IS FUEL INJECTED. ONE OF THOSE HAVE GONE BAD.
