is this what the inside of the RAD flywheel is supposed to look like?

[ger87410]

I see lobe in that pic:Banane19:
Your not looking in the right place.:banghead:

That certainly could be. I most likely don't know what i'm looking for.

Where is it at in the pic?

As usual you are trying to twist this around,the flywheel is the magnet,the AC generator is just that an AC generator.I would have thought you would have known that Matt,as such the lump or bump is merely an extension of the flywheel magnets that is close enough to the pickup that it creates a pulse when it passes by the Pickup-AC generator.

So the whole flywheel is a magnet? Are you sure about that? :bigok:

On a kawi flywheel you can remove all the magnets & it will run fine. You nick the lobe and it will run like crap.

The lobe has a magnet in it.
If you removed all the magnets, you would have removed the lobe as well.
I think when you're saying "magnets" you're talking about the bigger flywheel magnets responsible for charging & lighting.
I am including the small magnet (inside the lobe) that triggers the Hall effect sensor.
The triggering cannot work without a small magnet.
Fair enuff?

Matt is wrong on this one,he stated that at least one magnet controls the timing,The magnet controls nothing on that setup, the ac pulse from the pickup controls the timing

So if the AC pulse from the pickup controls the timing, what triggers the AC pulse? :bigok:
And if the magnet controls nothing, the ski will run fine without it, right? :biggthumpup:

nowhere was it stated there was no magnet involved in the process

Really?

Because its not a magnet its an ac generator and it sends a small ac pulse,non magnetic

:wavey:


:biggrin:

I am pretty sure at the moment you bolt a magnet to a piece of steel the whole thing becomes a magnet,WTF is this science 101?

Is there a magnet in the lobe?
If not, please tell me how the trigger pulse is generated.
I already did were you not paying attention again,shame on you :nana:
If you removed all the magnets, you would have removed the lobe as well.

Really?




:wavey:

Stop trying to twist and turn this you stated the magnet controls the timing ,I have already proven that is not the case,if you want to argue semantics I suppose we can do that for a couple of days if you like.:dance:

 

[ger87410]

If it's a magnet that's triggering a hall sensor, it's the magnet flipping the switch.

 

[Boris]

If a magnet falls in the woods,
does the bear still crap there ?

Edit: NM.

Pointless.

It is not a hall effect sensor, its an pulse coil or AC generator there is difference,I won't go into it here but Matt as our resident expert should be happy to will explain it to you.

Yes, there is a difference.

Which motors are you talking about when you say that they do not have Hall effect sensors?
I believe all the newer 2-strokes (SXRs and Yamaha 760 & 800/1200/1300included) with digital ignitions have them, as do MSD TL's.

The pulse coil/AC generator systems are for older ignitions, such as the 650/701 Yamahas and (I believe) the 650 Kawis.

What motors are you talking about specifically? Are we still on SXRs? :dunno:

 

[Big Kahuna]

good question, I thought he said it was a jeti..lol if it's a rad, then call rad...lol duh.

Kinda hard to do that now.

I am pretty damn sure the SXR uses a pulse coil-AC generator setup that puts out about .4-.5 AC volts,not a hall effect sensor.If thats not the case I am really unsure how you read .4-.5 AC volts between the green and blue wires when you spin the engine over.Care to explain that one Matt?

 

[Scorn800]

For the record my knowledge is strictly hands on & only on kawi's SXR's
I know certain brand flywheel have the lobe is different location to change timing.
Also if the lobe is damaged in will effect timing & once it is damaged the flywheel is junk. The oem cdi has more tolerance than a Advent. With oem cdi you can get away with some damage to lobe and the boat will still run, not good but run

man, this is bullcrap, you guys argued the whole damned thing while I was gone. I wanted to argue too damnit...lol

Well you and Matt have at it,I am going to bed have fun!:deadhorse:

anh... but scorn said it's a DC coil.... :swordfight:


lol

 

[Scorn800]

anh... but scorn said it's a DC coil.... :swordfight:

I'm tried too.
It's still early for Matt E go have fun with him
:Banane19:

 

[the WaTeRhAwK]

Ugh. Completely wrong.

An AC CDI takes its current directly from the stator. You can start the ski, take the battery out, and it still runs.

A DC CDI takes the current directly from the battery. Remove the battery and the ski stops.
MSD Enhancers work that way.

As for why would you do that? Well, think about it.
The AC output of the stator depends on motor RPM, making for inconsistent spark output at low RPM.
A DC system circumvents that problem altogether.

Someone correct me if I am wrong, please.

I was being sarcastic, matt.


I was telling him that there's no reason for them to go to the trouble to take DC voltage, convert it to AC, then back to DC again, regarding the "DC coil" comment. you mean an sxr will cease to run if you unhook the battery? I doubt it.

Sure. A hall effect sensor also puts out a signal roughly 0-1VAC and has two wires.

The SXR uses a digital DC-CDI (see specs on Kawi's website if you don't believe me).
As such, it wouldn't use the older pulser coil setup.

If you still don't believe me, check out the parts microfiche, section "Generator", and look at the small rectangular box coming off the stator leads.
That is the Hall effect sensor.
The coils on the stator itself are lighting and charging coils.
You will find identical setups on the Yamaha ignitions (760/800/1200/1300)

You're wrong on the SX-R using a pulser coil. Not trying to give you a hard time, please don't misunderstand me.
Btw, this applies to all years of the SX-R.


And if you want another angle to look at it, if it were indeed a pulser coil setup, the ignition would cease to work once you knock all the magnets (sans lobe) off the flywheel.

 

[the WaTeRhAwK]

so you think his sxr will "kill" at the disconnect of the battery? lanyard?

I thought the lanyards on the new setups worked off of a relay.

 

[Matt_E]

Yes.
