SHOW ME YOUR SPARK-PLUGS

Alright, I know there are many threads on here about it but I would like to see how your sparkplug look like and your opinions on mine.

I went down from 78 to 76 Main... I think I was too rich on this circuit.

Left the Inter at 32 and a 60 Air bleed.

And for those interested in this subject, also see: WHAT JETS DO YOU RUN

I put brand new spark plugs and I will take it out for a ride later on this afternoon.

These are from this morning.

This will be interesting. I am going to change my plugs and wires soon and I would like to see how mine fair to others. I will post pics of mine when I yank them.

Yes these are with the 78 jet. I have had no time to go for a ride with the 76. I will go tomorrow with new plugs also.

Really? I am thinking to drop the Inter from 32 to 31 too.....

Keep in mind its very cold now (colder air = more oxygen = leaner) by spring summer it should be just right?

I think I have almost totally dialed up.... no sneezing and no back firing at all.... it goes like a rocket!!

How to adjust your carb and check jetting

This is a hot topic... posting the thread may help... here's a improved version of what we have told COUNTLESS people.

To adjust the carb...

Some educational reading by S&S

S&S carb adjustments
S&S Shorty Carburetor Adjustments

S&S Carb Manual
S&S Cycle ::

For my 2 cents...

with the bike warm...
(in=clockwise/out=counter)

if your idle is low... turn it up a bit...

now spin in the accel pump screw till it seats.

now spin in your fuel/air mix screw till the motor sounds like it wants to die

now spin it back out counting 1/4 turns. Do it slowly to give the motor/carb time to adjust. Do this till the motor sound like it wants to die on this end. Now you have counted those turns and you have say 2.5 turns. Spin it back in 1.25 turns. Or middle to almost dead on each end.

Now adjust your idle to 1,000 rpms on the tach.

Now spin the accell pump screw out 1.5 turns

Now with a few quick stabs at the throttle see if the rpms come up fast like you would think or if it kinda hesitates then takes off. If it does hesitate then spin the accel pump out another 1/4 turn and repeat till you get what sounds good.

If that don't fix the sneeze... you can spin out the accel pump a bit more... but anything over 2.5 turns MAY mean you need a larger intermiediate jet. This is a common debate.

Then re-adjust your idle to about 1,000 RPMs. Too low and it may die. Too high and it will clunk into first gear.


Now on the plugs... to test run the bike and see if the jets are good. This can also be done before you ever screw with your jets.

Check or replace plugs.

run the bike but keep the RPMS below 2500... then don't let it idle and kill the motor, check the plugs. That is to help check the int jet.

Then take it out and run it hard... keep the RPMs up and romp on it... then on a striaght patch of road with the RPMs up high (over 3k, or even higher) kill the motor with the OFF switch. Pull the plugs and check. that is to test the main jet.

The idea here is that your int jet runs from idle to about 2750. Then the main kicks in from there out. That's why we say your run mainly on your int jet. main is only for romps.

Use this GUIDE to read your spark plugs. The basic idea is white is lean, black is rich. What you are aiming for is a nice cinnamon color to the grounding tip.

To talk jetting...

One of the most common problems is...if you are expierencing a cough at highway speed 75mph +/- RPMs at about 2750... cough thru the carb... go up on int. jet.

Of coarse once you change the jets you will need to re-adjust the carb again.

Keep in mind its very cold now (colder air = more oxygen = leaner) by spring summer it should be just right?
Ready? I don't lecture I more question myself and walk thru it so it makes common sense as I use science and abstract to explain myself. So to begin wit, see me laying in the sun? My balls were up my cavity, but with heat expansion, my nuts needed to cool off and I had to bury my nutsack it flowed out the 100% cotton briefs. [you wonder how many scrolled back to see :roll:]

Another example is the choke. I use the choke in the morning. Why? It's cold. Air condenses and that is more power is a tighter molecule next to each other. My choke has to choke more air from coming in is this ratio of air to fuel. So when I pull the choke, I force more pressure or a sucking vacuum over the jets and suck out more fuel.

I am going to force a rich condition and if I have more air condensed, I better find a way to add more proportion to the new air and change the ratio to match the tighter molecule position.

So if I say to keep in mind you think about the 3-science moves of the abstract: (colder air = more oxygen = leaner) is a proportion or a balance.

As the temp repeats an absolute as stated with the oxygen, the abstract continues in no certain order, because it is a loop you cannot get out of. By looking at the quote as a circle and now read it: Keep in mind its very cold now is that climate the bike's gas is in too.

We finish off the circle and close that loop with: by spring summer it should be just right? Yes, as he glances out the window on those days of days is any day go pick. And he is riding on those days is days of days you select a day. And on those days throughout the year, ask him if a driver driving with liquid in the winter, pulled the car over, changed the jets in the holly look out summer is coming. Pick that day of days in the, and no offense to the rubber meeting the road, but when he's driving the 4 wheel thing I forget what you call them, do you see many of them parked with their hoods up on those days of days of a weather change?

So if say the air temp is as condensed is the gasoline temp, are we not in a condensed state trying for a solid, but here is a liquid state in proportion? So if ice expands and cracks the block, didn't we condense or expand in proportion?

Yes, my air is condensed and lean is cold.
Yes, my choke is going to pull more fuel but in proportion as in change the temp and another fuel to air balances the science says solid/liquid/gas.
Yes, my bike/car starts sooner/faster as in an air to fuel ratio when choked.
Yes, my carb'd bike and car ran in all seasons and no jetting was changed.
Yes, my plugs are not even close to lean and keep in mind these bikes run rich or lean in pick a month, day, the snow-blower is late, won't start, is brand new out of the factory, has spark fuel and compression. Sure it won't start.
Yes, my rich would chuckloggagglexhaustack smoke like a mother and foul my plugs before I reach the first block is rich is that is rich!
Yes, my thighs are starting to burn; the heat on my chest is beginning to crisp my fur; the knocking is no matter the throttle opening is this thing is lean! I got to get off or diner is served; cooked sausage and meatballs.

Translation:
Dangerous lean is 18-AFR or higher is leaner or junk power: less fuel.
A 78 jet in the cold is for argument sake 13.5-AFR.
With a 78 jet setting the bike @ 13 is close to ideal performance.
A 76 jet for the argument round is 14.1-AFR and this is a lean is mean setting.
AT 78-j, I was running a cold torque setting.
At 76-j, I will run in an economy type jetting with a crispy clean bottom.
A 78-j would give me a strong torquey bottom end.
Conclusion? I believe franco is on the right path like planting seeds for the next solstice round.
A test ride will tell if the ass cracked a smile or, only your ambient knows for sure.

Your rich at idle and mid circuit.
Go down to the 31 and then test it with the 76.
You may have to go back up to the 78 but your not at risk going to 76.

Thank you Sven :2thumbs:

As some would say, "Clear as Mud" , but I do understand exactly what your saying! :whoop:

:cheers:


Will keep you posted shortly with the new plugs reading, today is raining so... Goretex suit on and will walk the small dog instead of riding the big dog. :D
 
I do allot of seat of the pants tuning and I see allot of plugs.
He asked a specific question, and if I'm not mistaken it wasn't anything about being lectured as to the intricacies of tuning a carb, so I gave my two cents. Take it leave it, doesn't matter to me.
Juz sayin.

Have you had a chance to run the bike since the most recent reject Franco?

Wow! Curtis, how can you tell all that from a photo?

Kap, your right.... I know how to play with my Carb.... and your right again (as I said b4) on the diagnosis. :up:

No, I have not have had a chance yet as its raining today... so I put my goretex on and I walked the small dog instead.

I will keep you all posted asap.

If I remember correctly, weren't you at 31 and 76 before the cam install.
Your correct Ker,

I am starting to wonder if I "jumped the gun" going to 32 - 78 just "by earr"...
I think I will ok with 31-76. I am going to try it.

BTW.... Do not open too much the pump.... there is no need... 1-!/4 is enough... :up:

Sounds to me like you know what you're doing. I don't have experience beyond my own scoots, so the cheat sheets help. Gas Man's post, that I reposted, seems to be more applicable to dyno tuning.

Appreciate your input.:2thumbs:
