Why not put his own phone number on a public forum? He's obviously quite happy to do so and he doesn't need other people telling him what to do. Man, this shit pisses me off. I want to live my life and do what I want to do. Just the same as him.

Leave him be. If he wants to put his phone number on a public forum then it's his choice, not yours.

And Megazoid, sounds like your a dork for believing him. 4 strokes SHOULD NOT SMOKE AT ALL. If a 4 stroke is smoking, you just tuned it etc then it'll probably be major. Unless it wasn't tuned properly. Shouldn't have wrung it's neck though.

/Rant over. Just annoys me to see others telling someone else what to do when there is no real problem

There HAS been a problem with people from KB abusing other peoples PH numbers.
It's already happened,I don't want to see it happen again.
So,,,there IS a problem,,,seems pretty relivent to me an that's why I posted it.

Everybody's quite right that the so-called mechanic was wrong to say the black smoke was normal. It ain't, and it has nothing whatever to do with the petrol you use. But a rich mixture would have lessened the possibility of piston seizure. You broke it. An aging sportbike is going to break if you redline it. Put another old motor in and do the same and you'll end up with another busted engine.

Hi Jackrat. Thanks. I dont mind the odd call. I work as a Telecommunication tech at the moment, so its a bit of fun to trace those numbers back and call them (its instant if you have an exchange lock set up). Its even more fun when you give the police their number and address. Hehehe. Point taken tho. Was only trying to offer help to someone that has had a little bed advise.
HXC. Appreciate you living your life according to your own rules. Good on ya man.

You tried finding an FZR600 motor recently? They've all been snapped up and those that haven't are bloody dear for what they are... Most wreckers seem to want about 2 - 2.5k for one! FZR400 engines are a dime a dozen though, wreckers seem to have heaps of them lying around.

I have restored a few of these older bikes in the past (1970s) and allways worked on the theory that if they was not thrashed then they would just keep ticking. Now it sounds like the engine in question had issues, but its hard to say exactly what without having a good look. Because the engine was rung out resulting in failure, then the responsibility for the eventual death should, IMO fall completely on the operater. rather expensive lesson to have to learn, but do treat it as a lesson.

**quickbuck** · 11th February 2006, 08:57

Wringing an engine because it seems faulty will fix nothing!

It is like smacking a TV because it won't work.

It might feel better doing it, but you are doing nothing to fix the fault.

Infact ringing any engine to redline without load on it is no good. (Okay, with the exception of gas turbines and others, and I'm sure there are some others).

**Megazoid** · 12th February 2006, 09:39

thanks again all you guys for the words of advise, and this is personally for Jackrat... SCREW YOU!!!!!!!!!

now that's that out of the way...
(for one, i was wrong... i was really tired that morning after a night shift at the restourant... the bike is not 1986, it's 1989... infact 1986 is not when the bike was made... it is when i was made... woopsy...)
the reason why i was asking thous questions is because the dude precisely told me three stinking times that that smoke is ABSOLUTELY normal for a sport bike... it has to do with shitty new zealand gas, and that there's nothin that could or should be done. it is NOT because i'm a jerkhead and i want wege money out of anyone, it is simpely cause it is my first bike, and cause i knew NOTHING about taking care of it... but if there is still a person here that thinks that i am wrong, and i should not be angry at the dude at KG, THEN EXPLAIN WHY!!! not just say "oh, you morron, ofcause it was broke, dont blame it on the technician"... the bike sounded fine, the carbs were tuned, the engine sounded VERY happy... and the smoke has been explained to me by sertifyed technician as nothing to be worryed about...

all this is crap anyway... the only reason that i'm wrighting here is that my bike's dead... and this place is probably the only place that i can bitch about it with maybe a little hope of understanding... =(

i dont even thinking about restoring her anymore btw... gonna get a new job, and buy myself a new Suzuki Boulevard C50

I think you may be putting alot of faith in the link between the smoke and the failure. Were they related ? was the broken piston the cause of the problem in the first place. If he had said "it needs to be pulled down to check it" would you have paid the money ? Buy the new bike follow the instructions and get on with it.

**CLEAN CUT** · 12th February 2006, 11:04

It seems to me that a reality check is in order here. Other forum submissions have correctly stated that black smoke is a carburation problem. For gods sake , its a 20 year old motorcycle and something was going to give sooner or later!
It never ceases to amaze me how a culture has developed in New Zealand of blaming everyone but ones self! Contrary to the perverse culture propogated by the Labour Government the world does not actually owe us a living.
If I was in your shoes and had opened my mouth before thinking I'd now do the decent thing by publicly apologising in this forum to the poor guy at KG Motorcycles. He has a right to earn a decent living without ill thought and destructive bad mouthing. Do the decent thing and go and apologise to him face to face.

**Sniper** · 12th February 2006, 11:10

To put it bluntly mate, you bust the bike. The guy may have been wrong in telling you that the smoke was normal. But you can in no way relate that to the piston breaking without taking the motor apart before the incident. You may have been told the carbs were tuned perfect, but there is a possibility they weren't.

**R1madness** · 12th February 2006, 11:50

Dude. It a shit that this has happened to you. SInce you have had a bad experiance with bikes and it is your first one give me a call. I will help ya out.

Everyone else here should step back and remember when they knew nothing.

Sorry megazoid but there is no way the guy could have predicted that it was going to pop a piston. He is sort of right about the smoke too in a way. If the bike had not had any work done to it over the years it is likely that it would still run ok but be a a bit low in compression and a bit rich due to leaking valves. Even doing the valve clearances may not have stopped them leaking. Its a legasy of high revs and lack of mainaintence i am afraid.
Dont be put off. Bikes are cool.
