Corrected Spark Plug "BASE" Reading

Plummen... :laugh:

BTW all, this is what I started with...

Pre-Jetting:

didnt have many miles on those plugs?

Hey!!! The color of your plugs match your paint job!!!

Get a color tune chart.

I hope my plugs don't match my black bike. I'm running 34's with the plug removed. :laugh:

Yes but I fibbed the idle test by tweaking the pilots way out lean...

If you'll remember the story, I couldn't idle it in the testing bay and they wouldn't let me tweak so I pushed out of the bay, tweaked the carb's richer a 1/4 turn or less and passed...

:laugh: :laugh:

Now look at your's versus mine.... there you go who;s on the rich side.... ME!!!! :laugh:

i dont think i look too lean...you do?...seriously,although not perfect, i thought them to be within a safety range....not all black and sooty, but not all white and fluffy either.....school me o' wise one.....lol.....

No, yours look more like what I'm trying to achieve....
From the original color chart, you have that nice tan color we all look for.

You can see where your ~ 1/2 on the ground strap on 2 of the plugs so your about right in your plug hot/cold selection.

Your base ring has a full 360 turn of color but not layered soot... so jetting real close if not spot on.

Your porcelain doesn't seem to have black spots or metal specs adhered to it so not detonating inaccurately.

And the plug anode doesn't seem to be all misshaped or burned, rounded, melted...

I'd say your dead on or somewhere real close...

Damn you... :laugh: :laugh: :laugh:

Im running alot of fuel and wasting it as well. Bike never runs hot. Don't give a hoot what the plugs look like, but white aint right. Has to be rich to put out the most power. Any carb needle settings on 4rth clip means you've spun out, eyballs melted brain farted, too hot in AZ. And when you getty done I'm gonna pass you just the same, seems all the money and all the problems you've had just don't add up together. The shoe isn't fitting. Are you located in an institution somewhere they let you surf the net? Is this for real? It's nice to tune things. To a point that is for a reason. I can picture you setting on a lawn chair eating a bolony sandwich while holding onto a fishing rod cast into the sand. your eyes never leave the spot where it lays. Flies buzz by and land on the sandwich, your wondering if they are in perfect tune or not. :woohoo:

Nads...... :laugh: You kill me brother... :laugh: :laugh:

Rich to put out most ponies... Hmmm..... :blink:
There's a difference of opinion on this one for sure...

Yes, you must have fuel flowing through the carbs but we're speaking in the regards of air/fuel mixture and jetting operations, not so much regarding flow here...

Too lean, yup, you'll hit flat spots, power lulls, popping exhaust, start pinging, pitting, melting piston thus metal particles that can lead up to holes in pistons, over heated engine etc... All in all, not good.

Too rich, fouled plugs, extensive carbon build up thus weak spark conditions, weak performance, carboned vlaves and combustion chambers, smoke etc... The OEM service manual also states this can also lead to piston deterioration such as depicted in the too lean conditions... :huh: All in all, not good

Now regarding money and issues/time... Well hell, sure I could have taken the bike over to Dyno/carb tuner and saved a lot of time and headache for ~ the same amount of $$$ jetting it myself and in time versus having this accomplished professionally.

But... this has been a new learning experience for me where I wanted to learn this art myself... In doing so by researching/studying the theory behind it all and in discussions with more experienced friends and professionals... I have learned a whole slew of information & experience on carb operations & jetting and have been able to witness the response and results in doing myself... Now how cool is that!

In each jet change and plug observations, I have been able to review the results first hand of how the bike responds to the change in starting, idle, low-mid-WOT range of operations, accelerations, decelerations (compression is like the brakes being on :woohoo: ), elevation changes and on the fly corrections etc.....

I guess this would be classified as the difference in a rider versus biker....

OMR

from all thr years of building motors from round track to cutting the front yard, milk chocolate colored plugs was the best for all-around perforance and duribility.

thanks, i stand vindicated...

When cold starting with enrichener = AFR 8:1
At Hot/normal idle = AFR 12:1
At average cruise (as per rider) = AFR 14.7:1
From there AFR should make a smooth slope richer to WOT = AFR 13.2:1
Trying to get as close as possible of course...
Some of these positions will tan/blacken your plugs whilst others will not...
Max power is always attainable without damage via jetting.
It's when you start changing physical engine properties that you can end up in #%&$!

We have used these guidelines for several machines (when a dyno with AFR was available) and the performance is astounding.
I can personally say that it is like pulling a brand new bike off the show room floor.
The power output is smooth and excellent, and the fuel economy is rediculous.

Aside from having a dyno with AFR, I hate reading plugs, PITA. I use my butt dynometer, and it works just fine!

Just my 2cents!

OMR, get that thing on a dyno with AFR and jet it right, ONCE. :laugh:
Peace.

"OMR, get that thing on a dyno with AFR and jet it right, ONCE. "...

Well what fun would that be? :laugh: :laugh:

I'm learning damn it, ok learning the hard way but learning just the same.... :S :laugh:

This process has actually showed me a lot regarding the carb operations and more specifically jet functions, what each jet does and how the engine as a whole responds to each change... All of which I needed to learn...

I get my jets for $4 each so the $$$ so I'm around a hunskie into it... Not too bad... Besides, it;s only the daughters college fund right.... :laugh:

BTW, what exactly is AFR reading a Dyno system?

True... I remember learning all that stuff for the first time

A dyno with an active air:fuel ratio measuring device. Makes tuning very fun and easy.

Cheers.

DOH!.... :blush: :laugh:

Easy I get, fun :huh: for whom the Dyno? :laugh:
I do realize the benefits received for exact tuning using a Dyno system as you have mentioned no doubt....

Thanks;)
