Re: Oh s**t
 

I've read your other thread...

OK to me your symptoms above sound simiply lilke a flat battery. But...

1. Dont panic. Think calmly about whats going on and try and give more information.

2. Last time you started the bike was the rattle getting worse, or was it accompanied by knocking, clunking or smokey oily exhaust.

3. Have you checked the oil level, if so how much is in there now ?

4. Worse thing you can do is to keep stopping and starting the bike without riding it, If you're not going to ride the bike dont start the engine.

Did the bike run last time you used it, albeit with the rattle ? When was the last time you used it ? What have you do since the last time it started OK.

If this is happening :

Ignition on, with alarm disabled ( if you have one ) Clutch in and thumb the starter and all you get is a sequence of buzzes, clicks and whirrs then IMHO your battery is flat. How bright are the headlights, are the idiot lights on the dashboard lit ? What happens to the rev counter needle is it spinning round the dial whislt the clicking noise is happening ?

If it fires and runs and then sounds like a bag of spanners rattling around in a toolbox then I think you might have a more serious problem that I'm not qualified or knowledgeable to diagnose.

its definately not battery cause had it dead before. I started the bike it was running with the knocking noise in the front cylinder, went to give a lil rev, heard *clank* bike died, sounds like somethings jammed, wont start now. not the sound of a dead battery i can guarentee this is to do with the cam chain/ tensioner.

HELP

Re: Oh s**t
 

Sounds something sinister in the engine, possibly cam-chain not being properly tensioned? Anyway, dont start the bike until the problem has been looked at by someone.

What a crappy thing to occur on your b/day :( but! things that go wrong can be put right, so dont dispair - theres a fix out there!

Re: Oh s**t
 

Could the cam chain of come off and got jammed, would that damage my engine?

Re: Oh s**t
 

Yes it would. If the cam chain is not tensioned properly, then (i think) the vales opening and closing will be out of synch with the pistons moving up and down; there is potential that a valve could be open when the pistion is at top dead center, where the top of the piston and the bottom of the valve would collide

I think?

I dunno

But thats what I think could happen

Re: Oh s**t
 

Is there enough oil in the engine??

Re: Oh s**t
 

How are you as a mechanic? I'd do 3 things immediately, I'd take off the cam covers and have a look, turn over the engine from the crank, and depending on what happens check the valve timing. No matter what you find you'd learn a lot. But you'd need to be fairly handy.

I don't think it's the cam chains, myself. If I was you I'd stop fixating on that, it's a very rare failure for the SV. What happens when you try to start it?

Re: Oh s**t
 

nothing at all just makes one tiny click noise from front cylinder then nothing, all lights stay on nothing dims. Whats the worst it could be and how bad could it possibly damage my engines from what ive said?

Re: Oh s**t
 

Does that mean i'd need a new engine?
