Question about Honda XR 250 R Motorcycles

Chat dirt bike problems

I have a 1997 Honda xr250r The carburetor was cleaned and it started up after a couple of kicks. After that it was stored for half a year. After sitting, I pulled it out, and washed it down, trying to get some of the dirt and dust off. After that I kicked it for about 45 minutes straight.It wouldn't crank. So I cleaned out the carb again, and then poured fresh gas into the tank. After that it still wouldn't crank up.It has good compression, and the spark plug is basically brand new,it was replaced after last carb cleaning. Could it be the CDI Box or ignition coil that's causing the it not to start, or another electrical aspect?

Could be coil or kill switch... check spark plug wire and contact by pulling off and checking if it will arc when held within 1/4" from a metal part close enough to reach... do this when dark so u can see the arc if and when it happens... if no arc then replace wire, then coil... Good luck

I would think about investing in a carb re-build kit.

SOURCE: VERY hard starting takes way to many kicks usually play out befo

There is a proper way to start the engine. Four controls are on your bike to assist in starting.

  • The choke, used when the engine is cold. Pull the red knob for choke.
  • The " Hot Start " Lever, used when the engine is hot. Pull the lever to lean the fuel mix when the engine has been running.
  • The de-compression lever, always used.
  • The throttle, used to prime the cylinder.
Don't kick, instead, push the kick lever downward. You will feel the back pressure as the piston is going upward on the compression stroke to the point the pressure is great enough that the kick lever "locks up". You are very close to TDC. NOW, pull in the de-compression lever. Push the kick lever a little bit more to get the piston past TDC. Release the de-compression lever. Give the throttle a 1/4 turn then let it snap closed. A diaphragm in the carb gives a shot of gas when this is done. DO NOT do this multiple times because you will flood the engine. Leave the throttle closed when kicking. Give a strong kick through the full sweep of the kickstart lever. Quickly get your foot off the kick lever at the end of the kick to avoid any chance of "kickback" from a backfire. It can be very painful, and can even break a leg. I am serious about that. Repeat the process (but without the throttle priming), until the bike starts. A good battery, a clean spark plug, a clean carb and clean air filter will also aid in starting.

Top rating for this answer? Thanks!

Take the carburetors apart and either rebuild them or clean them thoroughly.

It appears that your fuel to air ratio is off at half throttle. Is this model fuel injected?

SOURCE: Ignition problem with CB750K Honda

I have a 1980 CB750-F Super Sport and I went through this problem once.
After that long time, as MATHEW said, some gunk (gorilla snot) could be formed into the little carburetor's passages.
It will not come out if You don't "soak" the DISSASSEMBLED carburetors (without rubber parts) into carb cleaner for at least 6-8 hours.
After that, You can wash them with thinner, and then go on with compressed air.You'll be surprised with the amount of gunk that remained into the carburetor's bodies!!!
Good luck

Honda xr250 hard to start when cold


Hi, Andrew 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.
10. Enricher valve inoperative.
11. Engine lubricant to heavy (winter operation).
12. Ignition is not functioning properly (possible sensor failure).
13. Faulty ignition coil.
14. Valves sticking.

1987 Honda XR 250 R will not stay running after it warms up


Hi, Rrheston 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.

Have an 1995 xr250r and it won't start. when its cold only push starts, when its hot only starts some times or if its pushed. Thanks any surgestions?


Low compression can cause this. Insufficient valve tappet clearance is the most common cause of low compression on this engine. So, check the compression and, if it is lower that about 130 psi, have the valves adjusted.
Also make sure the kick starter actuated compression release isn't sticking after the kick starter is operated.
Another thing that can cause it to be difficult to start is a plugged up carburetor. If the bike has ever sat for more than about a year, then the carburetor needs to be disassembled and cleaned out.
