please help me with my speech

im in college and have to do an informational speech for my speech class. i decided on doing a speech about what all hapeens in the few seconds between you putting the key in a XJ series bike and it happily idleing away at 1050 rpm +-50 rpm. anyone like to help me??? as many details as possible

 

If the bike is like Andy0418s, nothing hapeens. :lol:

 

Dude!!!! That's cruel!!!!!

 

Very few things in life come close to the excitement of motorcycling (opening remark).

Even as you walk to the garage to unleash the beast you are ticking down the mental checklist that is part of the enthusiast's every ride.

Gas? Oil? Air pressure in the tires?

Then the donning of the gear begins. Frosty mornings require additional preparation; insulated Carhart coveralls, gloves, helmet liner, quick spray of "anti-fog" on the visor and you swing your leg over the saddle - always mounting from the left side of the bike (must be a throwback to the days of riding horse?)

The aniticipation builds as you reach for the ignition key and you feel the familiar butterflies in the stomach. Most mornings are still dark when you head off to work (school) and as you turn the key and the engine begins to turn over the single headlight comes on and pierces the darkness in a kind of "otherworldliness" and it all plays together to make your senses come alive and you feel as exhilirated as if you just snorted coke.

Then the engine catches and its steady thrumming between your legs fills you with desire that can only be satisfied by tapping the shifter into gear and with a few cracks to the throttle to speed the warm up you never felt more ready to face the adventures of a new day.

 

Geez! Is that what happens?

 

having ridden in The Blue Knights (LE only) i can tell you that ive gotten into the habit of mounting from the right as taught by a cumulative 125yrs of experience...

2 guesses as to why motor-cops mount and dismount from the right side...

 

Take-out window at the doughnut shop is on that side? :lol:

 

ok what i meant was what mechanically happens not the mental stimulus

 

Well egt, you havn't exactly hit a rich seam of intellectual stimulation here.

 

well it starts then it dies
well it starts then it dies
well it starts then it dies
well it starts then it dies
ohh crap i forgot the choke
well it starts then it dies
them verrrrmmmmmmmmmmmmmmmmmmmm
ahh crap the idle screw is to high kill the engine
well it starts then it dies
well it starts then it dies
well it starts then it dies
hmm ohhh i didn't turn on the fuel
well it starts then it dies
put it to pri
well it starts vermmm vermm vermm
let it warm up
take the choke off
then it dies crap no gas
walk down the street to go get gas
put the gas in
well it starts then it dies
well it starts then it dies
well it starts then it dies
well it starts then it dies
then it starts

all right get my gear on my gloves on my jacket on ahh crap i have to take off a glove to button up my helmet

look to the left
look to the right
make sure my turn signals work
push left ok good push right ok good
push in my horn waaaaweewaaa man that sound like a dieing cow
i open up the grage door
i pull in the clutch and mount form left to right
i walk the bike back wards then i push in the rear brake
it stops me
then i push in the front brake it stops me
i turn around the bike
i push down the shifter to first
then i rev the motor then slowly let go of the clutch
as i pull away i pull up the shifter to second


ahhh crap im out of time ill do this later

 

I squeeze the clutch and hold it in then I turn the key in extreme anticipation, a click, a spark, and then a multitude of explosions manifesting between my legs with a roar and a vibration to excite any man or woman who is able to tame it.

I release the clutch andhang on for what its worth as I Shift the beast to higher gears it feels angry and hungry for the taste of the road. The twist of the throttle, the injection of fuel and again More explosions moving me faster at my will.

The rush of the ride and the wind in my hair is finished as I reach my goal I Grip the brake and roll to a stop, I then twist the key back and the excitement ends just as fast as it had started only to repeat itself time and again.


( did you want a more detailed version detailing the TCI and Regulator?)

 

more of a technical expanation of what happens basicly the the TCI Ignition system

ive kind of got an idea of what goes on this is what i got so far:

key is turned to on

gets tci ready???

push in button completing the starter motor circuit

crankshaft starts spinning

crankshaft gets camchain moving

cam chain spins up the camshafts triggering certain cylinder(s) to intake fuel/air mixture

the engine pickups? send signals to the TCI ?

TCI sends current to the coil specifed ?????

coils creates spark in cylinder that has already intaked specified by the TCI's selection

ignition of cylinder(s)

engine starts to repeat the same process over and over

rider opens the starter motor circuit

engine idleing at 1050rpm +-50rpm

i know ive got to be missing something???

 

It must have to do with night stick or pistol smacking the bike.

 

I always get on the bike from the left hand side, but we drive on the left, so if you're parked parallel to traffic, getting on from the right means you're out on the road and nearer the cars. I would have assumed that in countries where people drive on the right, you would get on from the right.

Incidentally, if you want a laugh, sit on the Thai/Lao border for an hour or two. Drivers have about 100 yards to change sides. Many don't!

 

Wow. I never even thought about it, but I almost instinctively get on from the left too. Then I gave a LOT of thought to why, and came up with this:

Back in the day, virtually ALL motorcycles had kickstarters. Every kick-start bike I ever rode (mostly all British) had its kickstart lever on the right. You mount from the left, putting your left foot on the peg and stand up to bring your weight down on the kickstarter.
Which then makes me wonder if we all got into a bad habit because our bikes came from a place where they drive on the other side of the road?
And why do people who never rode kickstart bikes do it?

(sorry to hijack your thread, I can help with the startup sequence thing but it will have to be later)

 

When I took the Safety Course, they told us to get on always from the left, because if you slipped/fell your going to fall on the left side and because of the kick stand, you can't pull the bike onto yourself.

 

OK lets see if I can help by adding ot your sequence

Turn on switch - allows power to TCI and other ignition components

push in button completing the starter motor circuit

crankshaft starts spinning

crankshaft gets camchain moving

cam chain spins up the camshafts triggering certain cylinder(s) to intake fuel/air mixture

the engine pickup sends a signal to the TCI

TCI sends current to the coil

coils creates spark in 2 cylinders one of which has just completed it's compression stroke

ignition of cylinder

engine starts to repeat the same process over and over

rider opens the starter motor circuit

engine idleing at 1050rpm +-50rpm


Simplified but fairly accurate - hope that helps

 

With the bike leaning to the left because of the kickstand, it would be extremely difficult to mount from the right. Do the police motorcycles switch the side that their kickstands are on - because if they don't I have a hard time believing that you can lean a HD to the left and then dismount from the right especially considering that most motorcycle cops are short (after all, little man syndrome is what motivated them to join the police force in the first place .

 

The Harleys also have both hot exhaust on the right, scorching the pant legs! How's this: The cop gets off the left after pulling someone over. He's a bit nervous and distracted with radio communication, the chase, grabbing the ticket book, he somehow falls off the left, and his head ends up in the slow lane, across the white line.

Anyway,

The acids in the battery react with lead to free electrons, shoving them down the line, past the crusty fuse box and the previously mentioned relays, straight to the starter windings, creating magnetic fields that ultimately spin the motor. . .
The vacuum presented to the Pilot port draws fuel from the bottom of the float bowl, blending the fuel with a little air along the way, and squirting it down the hungry throat of the motor.
The oil pump starts working too.

 

The kickstand is on that side. Ergo, that's the way the bike leans. Would that have something to do with it, you think?

Then again, that raises two more questions:

1) WHY is the kickstand on that side;

2) Why do we get on the bike from the left side, even when the bike is on the center stand?

 

how did this thread get so off topic????

 

HAHAHAHAHA sorry... hahahaha

I think you just turned me on.....

Sorry we hijacked your thread.

I have no idea what happens, I turn the key, I choke it, I hit the starter... if that doesn't work I call my uncle.

 

actually the TCI opens the circuit to the proper coil, magnetic field collapses
inducing voltage in secondary windings, firing two sparkplugs

 

it opens the circuit i thought it would close the circuit on the coil thus pushing current the coil??

 

Now, wouldn't the first thing be, the battery has a charge? if not.. your first thought is CRAP!!!! I"ve got to push start this Freak'n thing.. so now.. is it the gear engaging?

 

ah your right i will have to add the battery to the list

 

it's a long story but the voltage is proportional to the speed of the magnetic field, it's faster collapsing than expanding
remember ignitions with points ? never mind, your too young
plug fires when points open

 

i get it it gives off a high voltage charge coming out of the coils that flows down the wire through the cap to the sparkplug and creating a quick high voltage spark ...am i on the right track....

 

thanks polock i did some addition research and now competely understand what you where trying to get at: http://www.sentex.net/~mwandel/cannon/sparky.html

 

now i just need a detailed description of how the TCI works?

 

got me there, has something to do with the ignition pickup coils down on the crankshaft end sending a voltage to change the bias of the T's in the TCI...?

 

Plagiarize this

 

thanks for the info wizard. so the TCI is operated by magnetic pickups on the end of the crank right? (i know im pushing for alot of info, but i dont want to go in front of the class and try to BS my through it, i have in the past though, but this is a topic i cant BS)

 

I believe that it's all gremlins and ghosts and puppy-dog tails inside.

But if not, then maybe this will help:

http://home.ptd.net/~theragos/tci%20faq's.htm

 

so from what i gather a tci in a nutshell is this:

1.a Transistorized Coil Ignition

2. does the following things:
A. detects when the magnetic pickups have passed the sensor(s)
B. acts to cut off current to a coil to collapse internal magnetic field of a coil thus creating a huge surge of high voltage current that is sent to the spark plugs that are located in the cylinders that are in or close to(depending on RPM) TDC(top dead center) position, one cylinder being in the exhaust TDC and the other in the compression TDC
C. advance ignition timing in accordance with engine RPM to compensate for less TDC time as RPM increases so that spark happens at aproximatly TDC

Does this seem ok to you guys?

 

Yep. Except it isn't trying to actually fire at TDC, there is a pre-determined amount of "advance" built in, optimized to the particular engine. That's why you shouldn't use a 650 TCI box on a 550, for instance.

 

Etg, now you are getting on top of your subject, well done.

 

Looks like another successful rescue from the hijackers 8)

Although that is a very interesting topic - perhaps a new thread?

 

Nope! Go read the info at the link that I posted, and you'll have a much better (and simpler) understanding of the whole thing. Pictures, too! Even a video.........

A research report, eh? Then recall the secrets of the great researchers from ancient times:


Plagiarize......
Let no one else's work evade your eyes!
So do not ever shade your eyes,
But plagiarize, plagiarize, plagiarize!

 

what about all the interlocks ?

 

what are interlocks???

 

Ignition interlock

 

nope i havent got a dui yet so i dont have to worry about that

 

Here's some info on the various interlocks.
Gamuru also has an interactive circuitry one that was cool.

thanks guys for all the help the speech went good a i got an A heres a picture of my art work on the whiteboard(excuse my lack of drawing skills)

 

Congratulations on the "A".

 

Cool Congrats!
