Sounds like this is the decompression lever area.. did you leave/forget something out?? This lever should have a cable connected to it... If you paid someone to do this... take it back!!

SOURCE: My Honda crf250r has trouble starting.

you better check for valve clearance.....and to be honest you're intake valve maybe to tight and kept open.....you will reajust it but this will last a ride or two...because maybe the mobdelium coating is done on the intake valve and it is getting tight all the time and kept open....put two new oem valve from honda and you will be back on the track....sometimes i also never rectify any angle on the seat of the valve, just put new one and go.....honda as getting better since 2007....more good quality of coating on the valve....if you bought new valve for an older model they will come with that upgraded and last longer.

The water pump seal is maybe gone.This would allow water into the trans.Get it checked and also that the bearing hasn,t spun in its location.This may cause the color change.Being a grey color,it may indicate aluminium in the oil.This may be the spun bearing turning in the housing.With what you wrote,I would get these things looked at.I hope this helps you

SOURCE: Valve adjustment

Hi CX'er, This is getting basic, but in a 4 stroke engine there are 2 TDC spots . One being the completion of the exhaust stroke, and the second is the completion of the compression stroke . Give her one more turn and the valves will close . I hope that you are using the 17mm port under the radiator to turn the engine . It is the same as the port you are using to view the flywheel markings . Before I begin for the first time, I re-torque the heads . You must use a torque wrench, or risk breaking a bolt ! If you do it afterwards, your valve clearance settings will change . Accuracy is very important, check for tight drag, and check with next thinner for free clearance . Too tight can burn an exhaust valve . I set them to a tight drag, about .001 under, but I verify the clearance, twice . When you do the left side, don't forget to loosen the 10mm cam chain adjusting nut one turn (in front of the flywheel view port). Listen for the little click as the tension spring snaps in to take up the slack, and tighten, that's it . Make 'em purr, J

Hi, Anonymous and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery damaged or nearly discharged, should have 12.5 volts.
4. 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.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.
8. Intake air leak.
9. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.

2006 Honda CRF 250 R will not kick start


Hi, Chad_chiasso 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.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. 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, kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.
21. Tilt sensor needs a reset.
22. Security system not disarming alarm needs a reset.
23. Check for engine trouble codes.

2008 Honda CRF 250 R after the bike is warmed up it will not start


Hi, Holdennguyen your bike starts great when cold but once it reaches operating temperature and the engine is shut off for a few minutes then you try to restart it and it will turn over but will not fire or it doesn't do anything, the usual suspects are:
1. When electronics get hot they build up resistance then stop working. It might be an ignition coil, stator, CDI unit etc. First, you must find out if the spark dies out. When the bike won't start, pull a plug wire off, stick a new spark plug in the end and ground the threads on bare metal while someone cranks the engine over. You should see a nice big blue spark between the spark plug gap. Incorrect spark plug gap will cause or contribute to a no start when hot issue.
2. Fuel Tuners have been known to cause this type of problem, disconnect it and see if resolves the issue.
3. Any engine management sensor could be faulty especially the ones that monitor temperature.
4. Gas cap not venting properly, improperly routed fuel lines they must always go down from the gas tank to the carburetor never in any kind of a loop this will cause a vapor lock. Clogged, bent, kinked, pinched or restricted carburetor vent lines will do the same.
5. Overhead camshaft valves adjusted too tight when cold, this will cause loss of compression when hot, except for pushrod engines they usually get looser when hot.
