Properly killing the engine

[zamanakhan]

When iam done riding i turn off the fuel petcock while the motor is on and wait for the rpms to raise just a lil bit before i turn it off. This pretty much gets rid of the gas that should be in the carb, is this a stupid idea? am i wreckin the engine? should i just turn the petcock to off and then just hit the kill switch? or does it even make a diffrence?

Disconnect the white wire and the Kill switch.
If you want to put a switch on the blue line.
The kill switch is bad on the magneto.

I run Bule coil wire to blue cdi wire.
Black coil wir to Black CDI.

The white wire is disconnected or could be used for small low powered lights.

I just put the choke all the way to close and give it full throttle to shut her off.

Sure it sucks in some fuel oil but i feel it keep things lubed up.
A little extra oil never hurt.

When i'm done for the day & heading home i turn the fuel off & when i'm out of gas i coast into my driveway....good how u can judge it coming from any direction.

Yup ..that's the way I do it..even though I have a kill switch...less gas smell when I put it in the garage....figured out how far away to shut the fuel off..pull in the drive, get off, take two steps back, put my hand in the air and it stops (just for the neighbors who might be watching)

There is nothing wrong with using the white wire for a kill switch. That's what it is intended for, not for lights. If you run lights off this wire, you will be drawing energy from your ignition system, like a partial kill switch and will reduce spark to a degree.

Death by starvation

I don't know if its the best idea to always kill the motor by starving it of fuel. these are two cycle motors after all and no fuel means no lubrication. I can't be certain if this is the proper way or not but I have had no problem lately with using the white wire hooked up to the built in kill switch on the throttle.

I did replace my throttle/kill switch a few months ago because not only was it shorting out, but it finally wore to the point of braking into pieces. I ordered a new one from BikeBerry and it has worked well since then.

I now have zero parts that came from my original kit I got on ebay. On the other hand I think of it as a one hundred a fifty dollar (including shipping) coarse in two cycle motor bicycle mechanics.Thanks to this sight, I can now rebuild one of these things in about an hour if I am not too distracted, although I have yet to take apart the lower end/transmission yet but I still have a spare one to rip into just to see how these things tick.

Well it has been said around here that shorting the magneto to kill the motor may take some life away from it.

Putting a switch on the blue wire dosen't short anything out.
Better for the magneto.

Like i said i like to fully choke my engine and give it full throttle.
Running it out of gas has to be harder on the motor.

No lube when it runs out of gas and also no lube when you start it back up.
The cylinder is dry.

Maybe only momentarily but i'm sure after time it has some effect.
Choking it floods out the engine keeping things nice and lubed up.

But that is only my opinion and my bike stays outside.

Does anyone with a good mechanic brain know if this can hurt the engine or carburetor or anything, in any way? This might be the best/most healthy way to kill the engine, from what I think. But on the other hand I’m just some kid. -I haven’t taken any mechanic training courses before-

Putting a switch on the blue wire doesn’t short anything out.
Better for the magneto.

And what’s up with this about kill switch and magneto? I've never heard this shorter engine life theory before. How’s the kill switch bad for the magneto?... let alone when it’s connected to the white wire? I’m curious

The kill switch dosent hurt motor life.
Thats not what i was saying.

I was saying it hurts the life of the magneto.
If you search "NO SPARK" on this forum you will find out the details of the Blue Wire.

Other members have had alot of troubles with the magnetos and the Kill Switches.
They decided it was better to disconnect the kill switch " White Wire " and run only the blue and black to the CDI.

Normally the white wire when you press the kill switch shorts out to Ground the green wire from the throttle.

So you are actually shorting out the magneto to kill the motor.

Now a switch on the blue wire just connects disconnects power to the CDI.

I think the problem with mags going bad is just that... bad mags.

Shorting the mag should have no effect on it, unless you were coasting down a mountain, and held the switch closed for miles.
