    Hello,

    I just got my FZR today (2kr - 1988). Rides beautifully! There are a few things though....

    1) A little red "SPEED" light flashes on when i go over 80kph! Did my head in because why put that light there at such a low speed? Is it telling me to settle down!????????

    2) I gave it a full wash after the first ride, and when i tried to start is it wouldn't. Sounded like the battery was dead (but it is a new one). I think maybe the lead heads may have got wet??? Any ideas? It did start eventually though and runs perfectly again.

    3) The clutch doesn't release smoothly, it is a jerky and stiff release. Does this just require a bit of air down the line or oil??? How do i do that?

    Thanks guys,
    Damien.

    cool, sounds good. Uh, the speed light is fine. That's exactly what should happen there.

    If the bike is starting straight away again, then maybe you did cause some kind of short. See if the problem repeats itself before jumping the gun.

    Uhm, and for the clutch, well mines apparently different to everyone elses. Everyone says the clutch is quite tight, and you only have like half an inch of play. Thats probably why its jerky. You can adjust the cable so that it releases a bit earlier. There's a thread somewhere saying how to do this.. That'll probably make the clutch a bit smoother for you.

    Here we go:

    Thanks Timbus,

    I already tried that for the clutch, that just made the catching point closer to the handles.....didn't really need that. The actual stiffness and jerkiness is in the whole release motion. For instance, when i slowly let the clutch out it sort of stops then slides a bit to catch up and then stops again (these stops are probably only 1/10th of a second and 0.1mm but it does affect release). It almost feels like there is rust or dirt in around the cable and it is having trouble getting back to its neutral position.

    Does that help the explanation?

    Thanks again.

    ahh, i see what you mean. Well, I did this with my exup cables, and it'd work with the clutch cable too:
    Remove the cable, hang it up, and spray CRC or WD40 down the top of the cable. If it's really stiff move it around inside the casing to loosen any dirt/rust.

    That should clean and kinda lube the chain nicely. I don't think you need to actually lube it, but if you feel the need, chuck some graphite in the cable ends.

    It might also be the clutch spring, which is located under the fuel tank. Might be under the fuel pump (wouldn't know because I don't have a pump). If the spring is soft it would jerk and not spring back either.

    Oh, might add that it could also be the clutch lever on the handlebars, or the other clutch lever - the one that attaches to the clutch - located after the spring under the fuel tank. If its NONE of those, its the actual clutch itself, and you might need a new basket/plates. But thats a last resort (and pretty unlikely).

    Damien, my clutch was like yours and I used normal engine oil (new) on the cable. It has loosened up a fair bit and is a lot easier to get away without stalling.

    I only pulled the cable out of the lever to do it.

    Would have been a bit easier to lube if the cable was out.

    will try

    Thanks for that guys, i'll give the engine oil a go, and if that doesn't work i'll try graphite. Also, i've heard of people using some sort of canned air to shot through the cable's casing. Is this possible????

    Damien.

    Sure it is. All you have to do is remove the cable from the sheath and then spay some air down it with an air compressor. Failing an air compressor you can get above mentioned cans of compressed air from electronics places, they use it to remove dust from computer parts and the like.

    After saying that I have never done it myself and don’t know how helpful it would be.

    I didn’t think you had to lube cables with nylon sheaths, I once heard that if you do it can lead to the sheath swelling and grabbing on the cable?

    Although you most likely won't have to use graphite if you try oil, just make sure to clean off all the oil before you apply graphite. Oily graphite ain't so good.

    Yeah I thought something like that might happen too. Thats why I suggested a dry lube. But Dave has had no problems, so...

    just so you know - that speed light comes on at 80 because that is the limit in Japan. As all fzr's were grey imports this was never changed for the australian market.

    As for the wash and no start - did you wash with fairings off? How did you wash (high pressure wash, or good ol' elbow grease)? I wouldn't have expected normal elbow grease with fairings on to cause any problems (I guess it depends on how much water too). High pressure could depending where you point it...

    But as Timbus said - if it works fine now it probably was just a short somewhere due to water. Hopefully it is not one that will act up when the bike is rained on (and if it is you will need to track the problem down).

    Perhaps you have done what I did once or twice and try and start while it was in gear ?? and then wonder why it wouldn't go?? <!-- s:oops: --><img src="{SMILIES_PATH}/icon_redface.gif" alt=":oops:" title="Embarassed" /><!-- s:oops: -->

    OK Here goes...

    Ok guys,

    Got some new info today. Took her out for a ride and a little hose under the tank near the carbys started leaking fuel. It was pissing out, but only when the bike was started. Also, the brand new battery went dead!! I had to use a battery pack to get to the mechanic, and this is what his other mechanic said:

    1) The leak "looks like overflow", but as i told him the tank wasn't full. He's checking on this over the next couple of days. I'll get back and post on the issue when it's fixed.

    2) The battery is not being charged at all while running, which means the alternator is ****** (some "revolutionator?????" component or something).

    3) There is now another problem (getting tired of that ***king statement); the front brake light only turns on when it's squeezewd very slowly and gently. When it is slammed on, there is only a faint flicker. Don't know what this problem is but may be related to point 2 above...we'll see.

    Other than all that garbage the bike actually sounds awesome, and goes like a little rocket - very enjoyable. As for the washing Boz, i did use the mechanics high pressure hose, which i won't do again. There was even a bit of water spitting out of the exhaust when i started here after that - LESSON LEARNT!

    I'll keep you all posted, thanks again,

    Damien.

    hey mate, sounds like you've got yourself a couple of "common garden variety" fzr problems. I can relate to the charging problem, i've had that with my bike.
    It could be the battery (you said its new, but are you sure it was fully charged before putting in your bike? - some batteries require pre-charging).
    It could be dirty electrical connections - pull the seats off to access the battery and clean the connection terminals and follow the wires, cleaning all connection points.
    It could be the regulator/rectifier, which is a small unit bolted onto the right-hand side (from memory) frame just behind the seat. Follow red wire from the battery to find it (you will have to remove fairings).
    Finally it could be the stator/rotor itself (pretty unlikely) behind the engine cover on the RHS.
    If you can get hold of a digital multimeter, check the voltage across the battery when the bike is off (should be around 12.5-13V). With the bike revved up to about 5000rpm, you should get at least 13-14V, indicating the engine is charging the battery. If you get less, the charging system ain't doing its job, for one of the reasons given above. You can isolate the problem by following a check-list with a multimeter, I'll try and find the link somewhere....

    It is fine to use a high pressure hose just have to keep it away from the electrical components and seals like on the forks and the chain etc.

    As for this small tube under the tank, are they originating from the carbs or are they before the carbs? There are four hoses that come from the carbs themselves but I am fairly sure they are all overflows or breathers of some description.

    When it comes to an alternator there are only really two parts, the stator and the rotor, never heard of a revolutionator.

    Thanks for the reply guys. As for the multimeter, the mechanic did that while i was there and said that it's not getting any charge to the battery, which is when he said it must be the alternator (sounded like revolution something, but may have been "regulator" don't remember). Anyway, he's fixing it over the next 2 days.

    The dripping fuel from the tube is my biggest concern, that and the front break light. I did leave the fuel tap to on overnight, could this be the leaking problem?

    I'll definitely give the connection terminals a clean when i get it back. What do i clean them with?

    Thanks again

    My fuel goes right to the carbies - bypassing the fuel tap. Needless to say, I have no way to turn the fuel off (seriously, I can grab the switch and swivel it like I'm a fuel-tap-DJ) yet I have had no flooding issues arise from this.

    However this may be different if you use a fuel pump.. somehow. Not sure.

    And the electrical problem.. Hmm, could be related to the first problem you had. In fact you may have shorted something with the water, while the bike was running, which led to regulator damage.
    I like to list worst case things, so don't fret. You might have just knocked a wire loose. The mechs will (should) know soon enough.

    i had the same prob with the front brake light. I took the switch off on mine it was just one screw. In side the siled unit one of the littal brass bits had worn in to the plastic with a small bend in the right place it came back to life

    the light could also be related to your charging problems. Fix that first, then move onto the next...

    The regulator/rectifier can cause all the problems you describe and is an easy and relatively cheap fix. If it is the alternator then you will be looking at a lot more unfortunately (though I have not heard of an fzr with a bad alternator)

    I had my shims done about 2 weeks ago and my mac sed he took off the alternator cover and ther was croshon in side from the small opening he clened it out and toled me to do the same in 2 months. I dont no if this can cause a charging problem
