Open the carburetor air flap then press down on the accelerator lever like you are twisting the throttle do you see a stream of gas in the bowl? if not check your fuel filter and, or, float assembly

YAMAHA YZF R1 2000 NOT STARTING


A little more information is needed here. Is the bike turning over? Is the starter motor turning the engine over but not starting? Is it sputtering or coughing or backfiring?

Was it running and then just stopped? has it been sitting for a while and now won't start?

Engines need fuel, air, compression and spark to fire. Try the following. Try to start it and then:

1. pull the spark plugs. Are they wet? can you smell gas? If not you probably are not getting fuel to the engine for it to start. This bike probably has fuel injection. On many FI bikes, when you turn it on you can hear the fuel pump turn on. do you hear that? Look at the fuse box and see if you have a blown fuse for any critical functions such as fuel pump, ignition, etc.

How do the spark plugs look? Are they corroded and black and burned looking? Fouled spark plugs. Try replacing them. If they are whitish and look as if the metal as eroded away your engine is running lean and you need new plugs but also need to address running too lean or you will burn up your engine.

2. If spark plugs are wet you are getting gas. hold the base of the spark plug against metal such as the engine and press the starter. You should see a spark on the plug if it is properly grounded. If you don't see a spark then either your plugs are bad or you aren't getting spark due to a dead battery or a problem between the battery and the spark plug such as fuse box or an issue with chip that controls the engine.

3. How old is the battery? If you are having battery issues you probably can't run the starter but you might be having issues there as well.

4. If the bike is sputtering and backfiring it is probably a timing issue. I don't know your model of bike but I am pretty sure the timing is controlled by a chip. That may have issues or again, maybe a fuse that controls elements of the ignition system has blown. Are there any wires that have broken or have exposed metal that could be shorting? Any of the leads to the FI system come undone?

Fully charged battery on my 1996 cb500,choke out however wont fire up just does a little puff like sound


NO - SPARK
Check for spark at spark plug.
1. If no spark, test the wire to the coil with test light and see if you have power to coil.
2.If no power to coil, make sure your on/off button is on and working.Use test light.
A. Power at the switch but not at the coil indicates a broke wire from switch to coil.
B. NO power at the switch indicates ingintion switch is off or faulty and not sending power to your switch , make sure key is on. Use trest light.
3. If you have power to the coil but no spark from the coil - replace the coil

SPARK
Check for spark at the plug
1.If you have spark at the plug, but not starting - check that your carbs are getting gas.
2.Petcock Could be off, Fuel Filter could be clogged, Carbs could be dirty or clogged and your not getting any gas.
3.Pull spark plug - If no gas present then your not getting gas, if wet then you getting gas and your flooded. Make sure you have good gasoline, Bad gas won't burn.
or your bike is worn out and dont have any compression.

With Good gas, and Good Spark, and Good compresssion, the bike will run.

If your not getting gas to your motor through the carbs, pull carb off and thouroughly clean it.

Trouble starting but once started runs good


How long since your bike was properly serviced? Service includes oil, oil filter, air filter, spark plugs, valve clearance check, fuel filter etc. Check for cracked PCV vent hoses around throttle bodies. checking of throttle body sync. These bikes usually run very well when properly maintained. Trouble starting when cold could be caused by many different things.

Good Luck!

Hi there technician i need your help if you can.i have a 2002 honda fourtrax 350.the problem is the machine stalled when it was running.and it finally did i tried to start it i pumped a fuel from the carb...


Generally when you try dumping a little gas down the carb, or use starting fluid, and if it still does not even sputter, it is electrical and not a fuel problem.

I would use an inductive timing light to tell if you really have spark or not.

If there is no spark, then it is either ignition switch, the pickup or the coil. The coil is easily checked by a parts place like Autozone. Ignition switch can be checked with test light.

I HAVE A 350 ABOUT 4YRS OLD ABOUT TEN HOURS ON IT, I EMPTY THE GAS OUT EACH TIME IM DONE... WENT OUT TO START IT, FIRED ONCE THAN NOTHING, CHECKED PLUG IT WAS WET, CLEANED, CHECK GAP ALL FINE, HAD SPARK,...


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.

My 50cc mini bike starts then dies 5 secs after starting. why?


It sounds like you may have 2 problems

  • Bad gas
  • dpossible loose spark plug( bad compression)


Solution

dump out the gas put new in
Remove the spar plug and examine the plug if it is wet and black it is fouled
if it is white ad dry it is not getting gas

If you can replace the spark plug if not just clean it with a wire brush put back in and tighten

Finally make sure the spark plug wire is not lose

Best of luck to you
