99 CBR will start but wont run

Just bought a used CBR 600. Was running great for about a month and then while riding, it died. got it home and researched about of threads, pulled the engine apart and cleaned the carbs, but they weren't dirty at all. The engine will start with the full choke and run for 10 seconds, the whole time getting rougher until it dies. Any turn of the throttle and it completely dies. Anyone have any ideas?
Also checked the air filter and cleaned it, but didn't think to pull the plugs while I had it apart.

    It is a 99 Honda CBR 600.. Sorry new to the forum and was posting off of someone with a similar issue. I checked the fuel and it appeared good/not varnished, and there appeared no build up in the carburetor.

    Did not check the fuel filter but can check that fairly quickly. Didn't cross my mind since this came on so sudden.

    Thanks for any help you can provide, dont have a trailer and already had to push it a mile to get it home.. :)

    Is this a Honda CBR 600 or a Yamaha Vstar 1100 Classic? The troubleshooting is a bit different between the two.

My battery on my 94 Honda cbr 600 f2 wont hold a charge I jump it and it will run for a short while then die

With a voltmeter check to see if terminals show several volts higher than battery specs when bike is running. If so then replace battery. If not have charging system checked out.

Cbr 600 starts dies

I could be wrong but it sounds like your getting air in the gas lines. Is your gas cap tightening correct and working properly? Check all fuel lines to see if you have a crack or loose and air getting in.

My bike dies while riding

Sounds like it may be sucking air from one place or another. You may have a small hole in a fuel hose, problem with fuel filter, or just a weak connector where the tube makes a connection. Something a little more major would be a gasket under the carburetor needing replacement. Check the tubes first. A fault with gasoline that contains ethanol is that they bring on deterioration of fuel lines. This is the easiest fix.

1996 cbr f3 bogging

When you strip a set of carbs you should balance them after refitting. The kit isn't expensive and comes with instructions. It could be something as simple as the throttle cables are set up wrong(if one is opening first then the engine may work okay in 1st but bog when under greater load ie 2nd)

What kind of maintenance should i do to my 1989 cbr 600 f to keep it in tip top running condition

  • Change gearbox oil every 3000 miles. Change oil filter every 6000 miles. Use 10w40 motor oil. NEVER use synthetic lubricants as they can mess up the clutch.
  • Oil the chain every two weeks. Lube the control cables every oil filter change.
  • Keep the gas tank full in the cold months. This lessens internal tank rusting due to condensation in the tank. Drain the carbs when the bike will sit over the winter unless you plan on starting the bike every two weeks and letting it run for 15 minutes each time.
  • Be sure the gas valve is turned off when the bike is not in use.
  • Get a 2 amp trickle charger and charge the battery once a week for 4 hours in the winter. Be sure to keep enough water in the battery to cover the top of the plates in each cell. Know that batteries only last two years or so.
  • Check the chain tension once a month during the summer riding season.
  • Please rate my answer. Thanks.

It all seems to be leading to fuel starvation. Have you checked the tank breather is not blocked which can be a small hole in the petrol cap or a tube from under the tank. It could also be a blocked fuel filter. There should be two. One inside the fuel tank under the petcock, another before the fuel pump. Here is the workshop manual where you can find all info you will ever need for this bike.

Thanks and good luck.

Runs for 30 minutes then dies

try running with fuel cap open. If it keeps running, breather in fuel cap blocked, strip fuel cap and clean.
