Carb adjustment ?

On my 05 ridgeback, when I snap the throttle it falls on it's face.

One step at a time.
1. When I am standing on the side of the bike, crack the throttle open it falls on its face.
2. When I am riding on the road, in said gear, [fill in the blanks] fast or slow, it falls its face.
3. When I gradually open the throttle there is no falling of the face.

Choose.

Franco has you covered there. If that doesn't get it, call me before you pull the bottom off the carb.

Check what Jets are you running!

Just for some idea: http://www.bigdogbiker.com/forums/fuel-air/14439-what-jets-do-you-run.html

There is nothing wrong with the bike. Do no mess with the carb. Why?

Let's move one step at a time:

1. Bike starts right up I hit the starter = Not the carb.
2. Bike idles like right now = It's not the carb.
3. Bike is not overheating within minutes of starting = It's not the carb.
4. Bike performs with a decent throttle application, no falling on its nose the slower I open it, no, it takes off well = It's not the carb.

What is it?

It's... Don't take offense to this so you steer clear of it... You are one footstep short of standing on my red carpet along with your wrist. Yes, I said you entered into squid territory. Squidwristing is the term. It's a deadly disease but temporary.

How do I get rid of it?

Stop doing it... Pay the cashier on your way out.

If you snap the throttle on on any s&s carberater until you get into higher rpms it will fall flat on its face because they are not a vacuum assist carberater. You have to roll into the throttle until you get rolling!!!

On my 05 ridgeback, when I snap the throttle it falls on it's face. I read the "how to" but it says before adjusting the accelerator pump I should make sure the carb is at stock settings. My question is, if I have 650 cam, head work, super trapp exhaust, etc., do I want to go back to stock setting? Right now I have to run octane booster to keep from spark knocking. Once again, I'm no mechanic, just trying to learn as I go and I definatly don't want to get it too lean or anything. I'm not sure of my jet size or anything. It was already set up by gateway when I bought it. Just trying to get some tips first. Thanks

How is it going Mate? Its been over 6 months now... All OK with the throttle?

Right on. I guess I'll just learn to get used to it. Thanks a lot

Guitty,
It's more you are fighting nature. Does this make sense so you can see what you need to live with; how to handle it once you know it? Lets think about movement of sound and movement of air. Slam those strings as fast as you can, sound is behind lagging. Even as close as you are to the instrument, my thinking is the speed keeps up, but you have that time lag no matter the distance. In other words, you see the flash of the fireworks, but the sound comes later, right? Same with the guitar string-to air-to sound = LAG TIME.

Slow now, we have a (solid-liquid)-gas out of the way. WOT is left is a liquid. Solid is not frozen is the gasoline per say, but say the gas is the liquid. Who in the WOT process is still in the LAG? = LIQUID.

Therefore, not a thing is wrong with the bike. There is something called a 'speed event' and that event can be traced to the guitar sound vs. pluck equals lag = TIME. So this transition is who do you think can keep up with lightening moving at the speed of light? It has to pass thru the air, yes? Flash then BOOM = LAG TIME.

So you just played that throttle cable as a string, ripped it a new asshole and gosh darn, the liquid stayed there is the lightening speed of the vacuum going back to 14.7 pee-yes-(in the)-eye I said; watch dishit you fuck with The PENULTIMATE NUMBER. THUS THE SPEED EVENT = VACUUM SPEED BACK TO ZERO... Left the liquid behind like 'Elvis left the building' is no gas equalized = LAG.

Signed,

NOLTT

I love it when people just ramble all sorts of reasons why you have the problems you have. No offense to anyone but if you don't know just don't say anything.

I have about the same thing you have, worked heads, higher compression 10.5 to 1, Woods 650 cam, adjustable timing, triple X (TAZ Carb) two thunder jets, FSD Sinful 3 D Exhaust. Here is what I run

Jets 33 intermediate and 78 Main jet.

Adjust the Air Mixture about 1 3/4 turns more or less. Then adjust the Accelerator Pump. The Accelerator pump should be at zero when adjusting the mixture. Once that is done adjust the Accelerator pump by turning it out 1 1/2 turns and snap the throttle, if it hesitates, turn it out 1/4 turn at a time until the hesitation is cleared and you are good to go. If it still won't throttle then you need to replace the accelerator pump. Hope that helps.

PS if you don't have 33/78 jets let me know and I'll send you some for free.

No offense to those who suggest their own jetting setup living in the mile high city and then JoeA lives at seal level... Here you go are the jet numbers. If you hear others ramble on about theory and science you are fighting, maybe a lot more science like altitude to jetting might be a smarter question to ask. JoeA goes right along with the suggestion and you wonder why bikes run so shitty are no fundamental theories to fall back on.

That old adage about teaching one how to fish, not catch your food ring a bell?

What?? Sounds like your carb isn't adjusted right. That should not be the case that's why they invented the accelerator pump. Read the S&S manual its clear as mud

ground pounder · Jul 12, 2015

Alls I know is I set u p the jets in a friends bike and we dynoed it and it was spot on!!! If you snapped the throttle from idle it would fall on its face!!! Get it going with rolling into it and then you could snap the throttle. So much for a S&S accelerator pump!!!

I have the same bike and I was told we dont have a pump because we dont have EFI. I do some of my own wrenching so I do understand what was said to me. We have a diaphragm on the bottom front of of carb. I cleaned mine and it is a bit crisper on the throttle response.

!+ Hole He Shits says, Vac You Us! 1+ He shits it out laughing it up... Snicker wit me on DIS!

The squid wrist vs. roll on wrist is what is being discussed here, as in "no problem found" is the point with a dyno to show all the power it can make that day on that day of the WACK OPEN is how I am going to hang my ass out, hope I am wrong, you are right. BUTT, Diddledent I say the "wristwistells all?" Even a spot on dyno run shows a super snap of air is the first to enter, like one opened the valve of that oil tanker, I'd like to see the [heavy liquid] fuel come in equallyou don't see it.

And I didn't drag you down the road wit your own whackshit abstract change my jet. Eventually it makes one the classic 'runner upper' you come running that shit thru a post. I choose my threads carefully as I expose the fallacy of the amateur = Lack of Experience.

So take No Offense to you weekend mechanics, but the reality is you are not going to compete with say a 'heavy line' mechanic, when they rebuild engines/trans/4x/rear ends is heavy line. There is a huge diff between WeeWee {weak end warrior], or the mech that takes a weekend off of the daily grind is grind yours to a halt... Fallacy/Fact Fukwit Me You Don't!

Signed,

NOLTT [is how it fits you to a tea] you don't get the theory! NMFF (not my fucking fault) I'm just the 'mini-steer of propaganda' is steer it on this side of reality.

Get it write or dunt right at all. LOL

PEE. YES.

ground pounder, WOT a mess you brought in with the dyno did you not? As if I am in my own world and my reality is man I have to question some of dem dare wee-wee'z out dare! No wonder why I use those meat puppets in my vids?! Meat Runner and Upper LOL

ground pounder · Jul 15, 2015

coolbreezin if you have a s&s carb on your bike then you do have an accelerator pump!!! the efi bikes have a fuel pump and fuel injectors.

Coolbreezin · Jul 15, 2015

Oh yea. You are correct. Got the names mixed up. Thanks for clarifying.

I can't thank you enough for this short but descriptive explanation. I have an 06 K9, and I've been experiencing this same problem, mostly between 5th and 6th beer. (No...thats not a typo...I tend to hammer on the throttle as I leave the local Watering Holes!) So, I've been checking/adjusting everything... carb, plugs, etc. I'll have to give this a try, but I'm convinced from your explanation that I simply need to Roll-In at lower RPMs. Once again, this Forum is filled with gold nuggets!
Thanks Ground Pounder!
