No Idle After Scar Mod!!!

[Shutterbug]

I did the Scar Mod yesterdy and added a Cyberhick A/F screw as well. I checked the hoses and could notfind any kinks. The bike willstart and run as long as I hold the throttle, but willnot idle. When I let the throttle go, it cuts off. I also adjusted the idle stop screw, no change.
I am stumped

Hey shutterbug, I guess you put the spring and O ring on the Hick Screw off you stock A/F. So How many turns out did you use for a starting point on the A/F?? 2--- 2 1/2 or what???

Yes, GG I replacedthe spring and o ring and stuff in the same order. Gave it 21/2 turns. Should I use moreor fewer turns on the screw?

The Hick screw is a little wider at the top than the stocker. I'd run it in to 2 turns and set the idel up a full round to start. How many shims did you use under the needle??

[Charlie D]

Also check and make sure where the choke enters the carb that it is down in the recess, sometimes mine will hang on top and bike will not run correctly till I make sure it is reseated.

Going to check it now.

2 shims. Don't understand what to do with the idle screw.

I'd just run it up where you know it's going to idel high. Did you get all the rubbers lined up right in the top, before you put the cap on?? Did the gasket line up on the air box side. With the small hole lined up where its suppost to be? I know you said no vacume lines were loose. But it's sounds alot like a leak to me. GG :D

[Green Ghost]

I'd Pm RETRO RICH, It may be tomorrow before he gets back to you, But I'm sure you two can get it straight. Wished I was closer sutterbug. GG :D

[Charlie D]

another Question, did you trim around half of the tit that the little spring is on (cap that holds needle in place)

another thing I had happen when I put the slide back in the needle did not enter into the jet, man I pulled my hair for around 2 hours till I found that mistake.

Charlie, I did trim the tit. Not sure about the slide.

[Retro Rich]

Sbug, Charlie D has hit the next thing I was going to tell you to do. Check the cap on your slider tube, when you put the tube back in after adding the shims under the needle you should have to "wrinkle" the diaphragm back down into the carb body. Make sure the little tab/"ear" is lined up correctly and seated into it's own recess in the carb body. Put the cap back on and tighten the screws down. Make sure you hook the vent line tube back onto the bottom of the tank as well (there's a nipple on the bottom rear of the tank, near the driver's seat that it seats onto).

Another question, did you take the carb off or tilt it out of the boot at all?? Also, when you put Hick's screw in--you turned it in and "lightly" seated it (turned it in clockwise gently until it just stops) and then turned it out 2&1/2 turns out.

I'm with GG as well; wish I were closer so I could get my hands on it for you.

[Shutterbug]

Rich, been working on my room additions and haven't been on the computer. I did seat the diaphragm as instructed, seated the Hick screw as instructed. I tilted the carb.I am going to dis assemble everything and re-do it. I've lost 3 days of riding time, I can't handle it!!!

[Retro Rich]

I'm thinking (oh, that's dangerous) that you might have popped a vac line loose when you tilted it out and didn't realize it. Make sure the one on the back of the carb is still hooked up (check all of them while you have the tank pulled). If that isn't it, post back and we'll get it figured out. Wish I was closer to 'ya---easier for me to look at it and do it than to tell you over the web.

[Shutterbug]

Thanks RR! I'll check them in the morning when I start the breakdown.

[Shutterbug]

OK, tonight I broke down the bike again except for the carb. There were no loos or disconnected vacuum hoses that I could find, and the hoses connected to the airbox were tight. Any more ideas before I tow it to the shop?

[Retro Rich]

Ok, the vac. lines are all hooked up (including the one that goes to the back of the carb body---correct??). You did a PAIR valve removal---correct? If you did, did you make sure to plug or cap off the "T" fitting that used to go to the PAIR system? Only other thing I can think of besides a vac. leak (which it sounds like that is what it still is to me) is to make sure that your slider tube is "clean" as a pin and it isn't "hanging up." But, usually this would actually keep it from revving and wouldn't affect the idle problem you're having.

Any way you can snap some pics of everything you touched and your vac. lines/hookups for us? Might help me/us diagnose the problem a little easier---hard for me to tell what you did when you were in there and if there's anything missing without actually seeing it. Just trying to save you some $$ and hoping we can figure it out.

RR

[Shutterbug]

Thanks, Rich. I'm going to break it down for a 3rd time and I'll take some photos. I did not do the pair valve yet, too many problems to deal with that right now.

[Charlie D]

not to make it sound bad but are you sure you are turning the idle adjuster.

one guy swore his was not working, he was turning the drain plug on the bottom of the stock air cleaner housing

Yeah, I'm turning the right one. If you don't pay attention, they could be confusing!

[Shutterbug]

OK, after a note from GG, I took off the airbox cover and filter, shot some gumout inside fired up the bike racing the motor. One thing I noticed was the black cylinder with the needle did not move. Is this normal?

[Retro Rich]

No, it's not normal....the slider tube should be moving. Sounds like something with the diaphragm isn't seated properly and you're getting a vacuum leak. When you re-installed the slider tube, with the little tab/"ear" positioned correctly on the right spot in the carb-casing---you did "wrinkle" the diaphragm back down in there---right? If not, take it apart and re-do it.

Well, irregardless sounds like you've got something wrong there.

Between you and GG, I may have just found the culprit!
I'll start disassembly immediately!!

[Shutterbug]

RR, I wrinkled the diaphram, now the black cylinder with the needle moves, but still no idle. I give up, I'm putting it in the shop tomorrow.

I have found that a few of the idel screws have a center that allows the splines on the cable to be screwed without moving the Idel adjustment screw. This was one reason I mentioned to run the idel screw in a full turn. Push the idel adjustment cable thumb screw back and forth a few times and look at the idel stop on the carb and make sure it's really turning the screw. If it is pulled out too far you can turn it all day and it does nothing. GG

I think that's my problem now. There is a phillips head screw inside the knob, what does that do?

[Shutterbug]

OK, GG.
Thanks for continuing to brainstorm. Guess what I found after your last message?
That's right, a loose idle screw attached to nothing!!!
I attached the screw and Voila!! It idles!!! My RedX is back on the road!! Thanks a million, GG and RR for hanging in there. The last 2 suggestions fixed the problems.

[epiphysis]

whew!!! I was getting annoyed with your dilema!! very interesting following this problem, even tho I have no desire to mess with the carb!! so glad you can ride again!!!!:cheers:

[psuedohippy]

Ive been following this and sorry for your problems shutterbug but at least some good will come out of it. This troubleshooting thread is going to be very helpfull for me and many others soon enough.

I shutter to think what a reputable shop might have charged you much less a lying bullcrap one. Im so not sure about a shop that ive been going to for my old honda that I almost am willing to stage this problem to see if he trys to rip me off or if he has been honest. Maybe thats too far, hmmm... would have to think about that a bit.

[Retro Rich]

Glad to hear you're back on the road Sbug.

Nice save there GG; sorry I wasn't on here last night. :)

Man, I think everyone was running out of ideas here. Wow glad it's running Shutterbug!!!!
I wish you could have hung around till SUN. Very nice ride. But on the other hand, WHAT A MAN, Ride'n threw the RAIN, SWEAT, AND WIND, With a Beanie Helmet, Sun Glasses, And No Shield. What a Man!!! I Enjoyed it just the same. Hope we get another chance to ride in the future. GG :D

[Shutterbug]

You guys are the best. I almost took it to the shop. Couldn't believe my eyes when I saw the idle screw hanging loose getting a suntan!
Thanks again to everyone who gave me pointers and items to check.

Next time if I know if there's going to be a hailstorm, I'll make sure not to wear a jacket or brain bucket---that's where the REAL pain begins! lol :D
