This is most likely a fuel related problem, unless you have electrical gremlins that are screwing with your ignition unit. Does it idle OK with the choke engaged, but dies when you disengage the choke and/or when revving the engine? In that case, your air/fuel mixture is probably way too lean. Could be dirt clogging up your fuel tap, fuel line, fuel filter or carbs..?

Try running some Seafoam or similar carb/jet cleaner through your system. If that doesn't work, take the carbs out and give them a good old manual clean.

1994 Honda CBR 900 RR will not start


Hi, John and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.

11. Fuel injectors clogged.

Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
14. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.

CBR954RR Starts perfectly every morning, no issue. Go out for a ride, bikes heats up. Stop for gas, or a toilet break, or lunch. Go to start and it acts like a dead battery... get click from starter motor...


Hi, Mt_jpn some bikes get "Sun Stroke" after running fine in the morning then shut off and parked in the sun for a couple of hours on a hot day. You get back on the bike hit the starter button and nothing happens or the engine turns over but will not fire. Then you put the bike in the shade for 20-30 minutes and it fires up no problem.
The primary reason for this phenomenon is faulty wire connections in the Starter and/or Ignition Circuit. You may have a wire connection/component that makes just enough contact when cool to start and run the bike, but when parked and exposed to direct sunlight heat causes expansion and creates an "OPEN" in the circuit not allowing the bike to start. You move the bike into the shade for a few minutes, the temperature goes down allowing the connection to contract and make better contact and suddenly "it's a miracle" the bike starts. I know what you're thinking that Gremlin could be anywhere, and you would be right in that assumption, you can take your bike to a dealer, spend tons of "DRACHMA" only to receive validated nervous emotions the next time you park in the sun, then 1 week later it doesn't start. Start by doing a ground check:
Check the battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary. Check all common grounds for the same suspects.
The secondary reason your bike may get "Sun Stroke" is vapor lock although this is a rare scenario it does happen.

Not sure what happened i started my 97 cbr600f3 ran it on choke for about 45 sec. it started to die,so i eased the choke off it died and havent been able to fire it up since.any suggestions


Remove plugs to see what colour they are. If sooty then too rich / clean / install.
If wet then flooded, dry refit.
If clean and dry, starving lack of fuel.

Misfire on plug no1


Replace a spark plug's cap and check it again.The 1rst and 4rth cylinders fires up together at the same time.So if the 4rth is ok you should start with the first cylinder's cap and coil cable replacement.
