20 Most Recent 1990 Honda XR 600 R Questions & Answers


Hi, Slb1986 if your headlight is not working, only one beam works, keeps burning out, blinking, dim or surges from bright to dim to bright the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chafed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/low beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator/lighting coil
11. Faulty voltage regulator/rectifier ground or overcharging.

Hi, Anonymous and the usual suspects are:
1. 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.
2. 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.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for spark leakage in the dark
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Dirty air filter.
10. Intake air leak.
11. Water, dirt, or rust in the fuel system.
12. Carburetor contaminated, sticky float, plugged jets.
13. Carburetor vacuum diaphragm torn, cracked, not seated or installed improperly.
14. Multiple carburetors out of sync.
15. Fuel filter clogged.
16. Old or contaminated fuel.
17. Fuel tank vent system plugged or carb vent line closed off.
18. Gas cap diaphragm valve faulty.
19. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
20. Carburetor controls misadjusted.
21. Incorrect valve timing.
22. Valve springs floating, weak, or broken.
23. Damaged intake or exhaust valve.
24. Incompatible performance parts.
25. Control module may be in "LIMP" mode
26. Check for engine trouble codes.

Does your bike have the decompression lever? If so this could be what is jamming up causing your problems.
Otherwise what often happens is that the kick starter cogs don't mesh correctly, seeing as how you have taken the kick starter apart and put it back again and now no probs I would expect that to be your problem.
It might be worth checking your kick starter for wear, or the return spring to see if it isn't broken.

Yes the plates do change dimension as it warms up, which will change the feel and lever adjustment. I would inspect the outer basket and inner drive hub for wear. Over time the steel plates will wear notches in the inner hub, and the friction plates will notch the basket as well, and when this occurs the clutch plates can't move freely and can't engage properly. Good luck!

Remember all Honda's are cold blooded. Make sure your gas is on, full choke, pull the decompression lever, no throttle, kick the engine over 3 or 4 times. Let go of the decompression lever. Now start the bike.

The charging system is over charging or you are putting the wrong replacement bulb in. My first thought is that the rectifier has burned out or somehow other malfunction. You will also need to check the battery as a malfunction in the rectifier will over charge the battery and actually boil the liquid (acid) out of it.

Sounds like a bad rectifier/regulator. Should be 12 volts

Carburetor jet is not adjustable. It has a precise hole size. For richer mixture, replace jet with larger hole.

Honda XR 600 R... | Answered on Sep 07, 2010


Hi,

Carburettors are notoriously difficult things to balance without the correct tools. I could not advise that you attempt to try this yourself as there are too many possible variations on the fuel mix and manifold vacuum pressure in the carbs.

The only way to balance carbs properly is to use a mercury manometer. The manometer measures intake manifold vacuume pressure and this tool is specifically designed to set the carbs properly. This will have a major effect on the overall performance of your bike.

Take your xr600 to a proper tuning shop and for a small fee they will set the carbs up properly for you. You will notice a major improvement in the bike and you will definitely not regret it!

Hi, Otis the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $20 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.
