1 Answer

XL883 appears to have no power --- open throttle and it doesn't respond --- doesn't seem to be missing - bad gas?

    The bike had been sitting for awhile and it just started acting like this today, April 27th. Single exhaust. Hadn't been riding due to the weather, it has probably been 10 days since it was ridden.

    What type of exhaust is on the bike? Is this something that just started suddenly? If the bike has been sitting up for a while, the carb may be screwed up on the inside but the bike would run real nasty if that was the case. I need more information.

I tried to answer this from an e-mail I got from FixYa, don't know if you got it. So, let's do it again.

Take the air cleaner cover and filter off so that you can see into the carb. With the engine OFF, crank the throttle wide open. As you twist the throttle grip, you should see a stream of fuel squirting into the carb. If you don't see this, the accelerator pump may not be working but this would cause the bike to stumble badly when trying to accelerate.

Now, start the engine and rev it a bit. Don't hold your face to close to the carb. Watch to see if the slide moves up and back down rapidly. If it doesn't, you may have a hole in the diaphragm that controls it.

Both of these scenarios are highly unlikely but possible. Try changing the fuel and see if that helps. What is so unusual is that you say the engine is not missing. When I asked if it had been sitting up I meant for about a year or longer. Sometimes the gasoline in the float bowl evaporates and gums up the jets in the carb but usually the bike spits back out of the carb and generally runs very badly.
Good Luck

"high rpm no power"

More detail would help, such as what are you working on, and fuller description of symptoms. If you are saying that as the engine revs, power seems to drop off, there are many possibilities. Clogged exhaust system (think bad cat converter), or bad ignition module (they have a low speed section and a high speed section), inadequate fuel delivery, gas pedal not opening throttle all the way, or if your vehicle is "fly-by wire", bad gas pedal section.

Spongy gas pedal

You will need to open the hood and have someone watch the throttle as you push the gas pedal, see if the throttle arm moves as you push on the pedal, this may be due to a bad cable or it may be off its holding bracket or loose. start with this test.

I have a 2003 Harley Davidson Sportster XL883 Hugger and it was parked for several months. Now it will start and idle fine but I can only open and close the throttle quickly. If I try to open throttle...

Did you clean out the old gas and put in fresh? Did you use a fuel stabilizer when you parked it? Have you changed the fuel filter? Have you pulled the spark plugs and inspect them?
If you didn't drain the fuel before parking it, or user a fuel stabilizer odds are you have a bunch of crud (technical term) in your fuel system now. And the crud could have fouled the plugs also; that's why when you try to open the throttle any more than the "blip" it's starving for gas. Probably already has something in a carburetor jet or in a float bowl. So drain out any gas in it, pour some alcohol in the tank, shake it around and drain it. Open up the fuel shut off valve and clean it. Change the fuel filter. Pull out the spark plugs and inspect; if their clean, blow them out with some compressed air and put them back in (after checking the gap) Put in fresh gas and try it. If it still behaves the same way, it's time to open up the carb and clean it. If it's beyond what you're comfortable working on, take it to a reputable shop to have it cleaned. Good luck

Stalling/popping while riding, takes tons of gas to get it to engage in first. Problems continue in second gear. It idles fine and starts right up. Bike is a 2002 Sportster XL883, but it has been upgraded...

It sounds like the accelerator pump has gone bad on you. Take the air filter off and with the engine OFF, crank the throttle to wide open. Watch the brass nozzle just inside the mouth of the carb for a sqirt of gas. If you don't see the shot of gas going into the carb, youe accelerator pump diaphragm needs to be replaced. This will require that the float bowl, and possibly the entire carb, be removed from the engine. Take the small accelerator pump cover off the bottom of the float bowl and change the diaphragm. This would be my best guess.

Good Luck

pull out the racks and remove the bottom floor of the oven,turn it on bake,if the ignitor doesn't glow most likely it's bad,if it does glow and it doesn't ignite within 40 to 60 seconds the ignitor is bad.even though it glows doesn't mean it's good,it works by takes 3.2 amps.for a flat ignitor to open the gas valve and 2.5 amps for a round ignitor to open the gas valve.

1999 Oldsmobile Silhouette. At times it seems

a bad tps sensor will cause: transmission shift issues, bucking, jerking, idle surging, engine cutoff, hesitation on takeoff, surge while cruising down highway. to check, remove connector from tps, use a ohms meter and probe center and any one of the other connectors,move throttle slow. if it jumps or does not stay steady while moving throttle, its bad. if the needle on ohms meter moves good then the tps is ok. move throttle plate slowly.
