I recently bought a 2001 cbr 600f4. it was dropped so i got it for cheap. there is no real significant damage to the outside, besides the front and side farings. but i cant get the thing started. i took the old battery out and ran jumper cables from my car battery (car was off). i solenoid clicking, but nothing from the starter. so i attached the positive cable directly to the starter cable. then all i got was the start making a clicking sound. this is my first bike and i don't have much knowledge of them. i do however have knowledge of car motors. so if anyone has any pointers for me, it would be much appreciated!!!!

humm,
try bump starting it,
to check if the engine can turn over. never know it might even fire up.
It maybe the case that the starter motor is seized, or the teeth shreaded or even a loose connection on the inside.


If the engine turns over, then check its getting fuel/air, and check the spark.

I had the same problem after i got my bike...it made a clicking that came from the starter relay. If the relay and the starter do nothing but click, its only because of a dead battery. Just put the battery in the back, start your car up, hook the jumper cables up from car to bike, and then it should start right up. :thumb:

Oh yeah, and then if it does start, ride it, or at least let it sit and run for a while...otherwise, you'll have to do the whole process over again.

i tried to "bump start" it and i also tried hooking the battery in my car to the cables on the bike. still just a clicking sound. when i tried to push start it the back tire just locks and the bike slides, but no start. im thinking it could be the starter is just bad. i also heard that maybe the clutch is just shot.

If the back tyre just locks up that is tellin me that something may be wrong with the bike. But being a honda tells me that it should be fine? Try and push start it in second or third gear, possibly down a nice grade if you are near one. Get it rollin, let out the clutch and givit a lil bit of gas. Possibly choke it a lil. If the tyre locks up then, there is a problem.

I'm gonna say that if the rear wheel is locking up, then either there's a major problem with the transmission, or even more likely the engine. We've got the starter solenoid clicking, so that means the solenoid is working. But the starter isn't turning the engine over, and bump starting it failed, which doesn't involve the starter at all.

So, since the bike is in neutral when you try to start it normally, I think we can rule out the transmission and clutch. Try pushing it and then simply letting the clutch out while the bike is in neutral still. If it starts to lock up, then yes there is something wrong with the clutch. If not, then the clutch can be ignored at this point in time, since it's not engaging when it shouldn't.

We can discount the starter since bump starting it doesn't involve the starter at all.

So more than likely, I think your engine has seized up somehow.

At this point, I'm sure that quite a few people will chime in with various suggestions about the fuel system or the ignition. While these are all good things to check since the bike is a few years old and clearly there are problems, they are somewhat moot. I say this because problems in either one of these would not prevent the engine from turning over, although they can prevent it from starting. But if your rear wheel is locking up during bump start, then clearly something is seized up and the engine itself is not turning over at all.

So unless you're willing and have the knowledge to tear apart your engine and see exactly what is wrong...it might be just cheaper and easier to get a new one.

What gear did you try to bump start it in? I had a 99 F4 and it had no engine problems but would lock up the rear with a cold tire if it was in FIRST gear. Second or third should work. If not then yeah, im gonna say get ready for a new motor. Sorry friend!

Good point. Make sure you're trying to bump start it in second or higher, rather than first.

I think before doing any more bump starting and since you don't know all the history, pull out the spark plugs. Maybe the engine is hydraulicing. That means a liquid (oil or coolant) is on top of the piston. You can't compress a liquid so it jams the engine. Try the starter or push it in 6th gear while the plugs are out. You may see something, I'm guessing oil, come flying out when you crank it. You must be cautiious though because trying to force the piston up when it can't will result in a see through piston and/or bent connecting rod.

did anyone even read my post?

It actually said most of that already in much less words.

The bump starting idea, was to see if the engine would turn over, then you could diagnose the fault after. :thumb:
For example if the engine wont start with a bump start that could mean its seized, and would be why the starter motor wont turn over.
The "locking up" he is describing could be his explanation of it rapidly slowing down, which vechiles do during a bump start, as the motor turns over.

I totaly agree with Denzee, :plus1: their may be fluid on the piston crown stoping the engine from compressing, and as he described correctly will bend the con-rods if you try to hard. so follow his advice with taking out the plugs, and checking for fluids on piston.

One thing you could try, would be to take the starter motor out, and then connecting the jump leads from the car to it, ground one out on the outside, attach the possitive to the possitive connection, if the starter motor turns then your engine has probably seized.

ya i definetly dont here it come on. someone metioned to me about a "tip over switch?" they said that it would cause the fuel pump to not come on if the bike had been dropped.

shuh!!! poor you. certainly asked a hot question. happened to mu bike once after it fell over. there is a tip over sensor on your front headlight cowl, just between the 2 headlights. sometimes they go faulty after a haevy drop. test and replace it if necessary. pricey though but lifesaving, about $80 from honda. wish you luck. as a rule of thumb, always eliminate the simpler posibilities before tampering with major things.

The 99 CBR F4 is carbureted not Fuel injected. Hence the F4i that came out in 2001. You won’t hear any F/I priming when you turn it on.

Just a question, did you check to be sure there is not bad or wet gas in it. And if it’s cold out you'll have to turn the choke all the way up since its carbureted.
