Honda CBR 600 1997 won't start - please help.?

Question

I have a honda cbr 600 f 1997 and it refuses to start, is it possible that a faulty alternator is stopping the bike from starting??
I have tried everything else and just wander if this is a possibility?

Answer 1

have you tried putting petrol in it

Answer 3

Not enough information in your question (does the engine turn over, but wont fire, or will it not even turn over?). Others have generally covered the requirement for fuel, spark and compression, so I'll not address that situation (if it turns over, but won't fire). Since you asked about a bad alternator (actually, on that bike, the stator and regulator), I'm assuming that you can't get the engine to turn over (no electricity to the starter). There are a couple of basic things to check, including battery charge (trickle charge it with a 1.5 amp charger, a typical car charger of 5-10 amps will fry a motorcycle battery in no time), check and clean connections at the battery cables (both ends, not just at the battery), connections at the starter, check the grounds on the bike frame for cleanliness and security, etc. In addition, Honda starter switches are wired in such a way that the contacts in them frequently "fry" and become unusable, thereby rendering it impossible to start the bike. This is caused by Honda's wiring the starter switch in the headlight circuit, resulting in a constant (and rather high) load on the somewhat fragile contacts in the starter switch. If this is the situation, it may be possible to repair your's, or it may require replacement. Go to http://www.rattlebars.com/mtz/starter.html for directions on correcting this situation. That link may also show how to remove the switch from the headlight circuit (a very good idea) to keep the situation from recurring. Hope this helps.

Answer 4

As others have eluded to no it won't stop the machine form starting. Fully charge the battery and stick it in. if the bike starts then tickety boo.

However there are 3 things an engine needs to run

Fuel
Compression
Spark

Assume you have fresh fuel in the tank. Turn the bike over a good few times and then whip out the spark plugs. If they are wet (assuming it didn't start) then bingo you have fuel getting through. If they are dry then there's your fault.

Compression - if you don't have a gauge then carfeully remove the plugs, push your thumb over the spark plug hole or stick a small bung in the hole but not to tightly. If you can feel pressure against your thumb on all cylinders or the small bung pops out then bingo you have compression. If not then there's your problem and a big one.

Spark - take the plugs out the head, connect them back up to the HT lead and hold the sparking end against the cylinder head. Turn the engine over and youshould see a spark at all of them. If not replace them to see if it helps. If it doesn't then your ignition system is suspect.

I ams ure you know all this anyway but no harm in adding it just in case.

Answer 5

The regulator/rectifier often fails on these. If it has, the battery won't have been getting a charge and therefore you won't be able to start the bike. Try charging the battery on a mains charger, then start it up - if it works, you then want to put a voltmeter across the battery terminals while the engine is running. Anything less than 13.5 volts (ideally it should be around, or just over 14 volts) means the reg/rec has died, and will need replacing. It's far less likely that your alternator has failed, but it's possible - it doesn't stop the bike from starting itself, but again it prevents the battery from getting a good charge.

Answer 6

It would help to have more history and info to help with your problem... has it always been this way, if not - when did the problem occur, did it come on fast or slow, etc, etc. Unfortunately, yahoo answers doesn't allow for a continuing dialogue.

Like others have said, the charging system won't directly affect starting, but the resultant drain on the battery might.

You should be able to push-start this year/model. Turn the key to on, run switch to on, put the bike in 2nd gear, hold in the clutch... start pushing, as fast as you can. Once you get up to speed, let the clutch out, and then quickly pull it back in when (hopefully) the engine kicks over. If she starts up - you know she will start, and can then go on to further investigate charging system / battery issues. If not... you're either pushing too slow, or there's something else wrong :)

Feel free to email me if you wish further assistance.

Answer 7

I doubt whether a faulty alternator will prevent your bike from starting. Alternators only recharge your battery once the engine is running, so its unlikely to be this. Presummably the engine turns over but doesn't fire up?? If this is the case, it can only be either fuel or ignition. Blocked fuel line, blocked carb jets, knackered HT leads, knackered spark plugs - that sort of thing.
Not much help, i know but with the limited info - the best I can offer.

Good luck, hope she is running soon :-)

Answer 8

If the engine spins when you push the starter button, don't worry about the alternator - it has nothing to do with running the engine.
1) Check for spark - change the spark plugs while the bike is apart.
2) Don't put it back together yet - if it still won't start, remove the carbs and clean them.

Answer 10

if the engine is turning over before ripping things apart give all the ignition leads and the coils a good spray with WD40 this may do the trick might just be damp my old XS 1100 would start on one cylinder when wet and as she warmed up the other 3 would start firing

Answer 11

check list; try to charge battery fully with a charger before you go at it again.
make sure fuel tap is turned on and if possible remove outlet pipe from fuel tap to check if fuel is flowing(no smoking)
has bike been fitted with an alarm? if so ,make sure it is deactivated.
check fuses??
can you hear fuel pump running?
try removing plug lead and placing it close to an earth.crank engine,check for a spark?
hope you a have some luck.
