Pulled my bike out today after sitting for over a year fired up after a couple tries. Then I decided to dump the gas and replace it with new gas. Got it to fire once but it wouldn't idle over 1000rpm and now won't fore at all. Need help.

2001 won't start after sitting 3 month winter in garage' New gas & full charge on Battery,turned over,,& fired but stalled,won't re-fire

Hi, John if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

Cranks no start or fire add gas down throat of carbs and it back fires out pipes and carbs

bikes that sit for long periods of time need there points or electronics pick-ups serviced , rust and aluminum corrosion happens over time on these

miss fires are sure signs of this to mean out of time

and yes the carbs/tank will need a total cleaning out too

Have a 2003 100th an. Harley Davidson 883 Hugger; bikes been sitting for a while and the battery needs to be changed, have not tried to start for quite some time couple of months, tried to start today and...

Get a new battery and charge it up fully. jumping bikes of a pickup can fry regulators.
drain the fuel from carbs, fit some new spark plugs and new oil, clean the air filter, then give it a try

Earlier today I tried to start my 800 vulcan classic but the bike would idle really rough then die so I put it back in the garage and decided to deal with it later. Just went back to the garage and there...

Has the bike been sitting??? If the carbs are gummed up from sitting and the float and or float needle get stuck in the "add fuel" position it could cause this

Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

I recommend that you go to any auto parts store and get an aerosol can of starting fluid. Shoot a couple of quick bursts into the air intake area and pull it. Repeat until it starts.

If you can have a second person operate the aerosol can for you it will go easier. Let it run on the starter fluid for a few seconds until the glaze in your carbeurator is cleared out.

In the future after you empty the gas out of your chain saw start it up and run it until it completely runs out of fuel.

Ran 1/2 gal bad gas truck started chugging check

Hi ! a easy way to possibly help this is to get a can of sea foam at the parts store and dump it in your tank it may help dissolve any goop that is in there and it helps renew bad gas ,also if this does not help remove your fuel filter and blow through it it may now have gotten a bit gumped up ,not a bad idea if you havnt done that for a few years anyway ,mostly the sea foam should help!

95 sportster wont start. Everything was running fine until now.

do a basic test .try starting the bike, then take out a spark plug. is it wet or dry? if its dry, no gas getting into the combustion chamber. if its wet, place the thread of the pluged in spark plug against any engine metal, crank the engine and look for a good blue spark. no spark or an orange spark means ignition problem.

1979 GS750L Engine running out of gas. Cleaned gas

vacuum opens the fuel tank petcock. The carbs have thier own means ofmetering fuel in the yhemselves. So, I'd say the carbs need to be pulled and cleaned, all jets should be cleared of corrosion and float levels ck'd if equiped. good luck.

Getting a fuel dump

Sounds like you need to clean the carbs out, as they are probably gummed/varnished badly after sitting for 2 years.
