Title: looking for info on carb or direct fit carb Post by bbcwby on 06/13/19 at 08:57:58 ok everyone here is what has been done, screaming eagle exhaust, timing chain update, ryca k&n filter and I have read and read and re-read about the jets. I did the jet update and its running so so rich it has made parts of the garage BLACK. what am I missing? is there a carb that I can buy that would be a direct fit. I just want to ride without all these problems. Bryan texas |

Title: Re: looking for info on carb or direct fit carb Post by LANCER on 06/13/19 at 09:39:18 It is the stock HD Dyna exhaust that most mention. The Screaming Eagle is not the same. What jets did you install in your carb and what is your pilot screw setting ? What part of the country do you live in ? |
|
Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/13/19 at 10:08:50 Lancer the jets I used were 152.5 and 55 plus the two washer update. And I live in Wichita Falls Texas. I also changed out the pilot screw with the carb rebuild kit and I screwed it in all the way and back it back out 1/4 turn. It runs great at idle but when you give it the gas it pops and bangs. any help would be great |

Title: Re: looking for info on carb or direct fit carb Post by verslagen1 on 06/13/19 at 10:33:17 I think you may have assembled your carb incorectly. please review and check your carb. Typical things that happen to newbs... install the jets in the wrong locations. white spacer below the needle. slide spring not straight. no washer under the main jet. cone filter that blocks the inlet to the slide diaphragm. |

Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/13/19 at 12:37:44 verslagen1, install the jets in the wrong locations. I only changed the main and pilot but I will double check white spacer below the needle. the white spacer mod I was real careful about how it went back, I looked at diagrams to see exactly how it went back together. But again I will double check slide spring not straight. ok on the slide spring are you talking about the big spring for the diaphragm? no washer under the main jet. I know I got this one correct cone filter that blocks the inlet to the slide diaphragm. well I am actually using the original black sleeve then I put I the ryca 90 and then the filter.. Thank you. I will take any all advise to correct this issue |

Yes, some how it's gets folded over on the end and won't allow the slide to operate. Also, make sure to seat the diaphragm correctly. All in all, sounds like you got it covered. But it sounds like there's a blockage somewhere or the main jet is way undersized. Screaming eagles are just about the same as no pipe at all. Most would have troubles getting to run right all thru the range. I'd clean the carb and up the jet a notch. |

Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/13/19 at 14:01:00 verslagen1, when I took the carb off last night I noticed the diaphragm was stuck at the top when I looked inside. I would think it would move freely up and down and not get stuck. Would that cause it to run so rich? and as far as the main jet - man I really thought I had to gone down a few sizes..I will mess around with it. but the diaphragm being stuck up has me bothered..any Idea on that? |

Well there's your problem. The white spacer goes on top of the needle clip,and the small spring goes under the clip. |

Title: Re: looking for info on carb or direct fit carb Post by batman on 06/13/19 at 15:48:50 and the air screw that came with the rebuild kit was probably the wrong one ,use the stock air screw . |
|
Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/13/19 at 15:50:57 Dave that was a typo, I got the white spacer mod on top. you can screw the plate down and see it. should the diaphragm be stuck up when its not running? |
|
Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/13/19 at 15:52:49 Batman yes I will be going back with the stock air screw tonight. I am hoping after all these great details and info it will run correctly. again if anyone has anymore info please let me know...i will take all i can get |
|
Title: Re: looking for info on carb or direct fit carb Post by batman on 06/13/19 at 17:28:59 About the only other thing to check is to be sure your float height is set right ,if that were to high it could make the carb run to rich . That height doesn't include the gasket. |
|
Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/14/19 at 06:48:33 GOOD MORNING EVERYONE, Well I went back with the stock air mix screw, and went down to 147.5 - 52.5 on the jets, cleaned it all up really good, made sure the diaphragm was not pitched and the big screw was straight. If any new people are looking at this post then please take this advice, cheap doesnt mean its good...but it still running just a smidge rich but it was late last night when I finished, so I will mess with it today. thanks everyone. |

Good news and great advice. If you feel you're still rich, I'd start with going down on the pilot and possibly a mild white spacer mod. I'm running a 47.5 pilot with a 147.5 main and a 3/4 spacer mod and having pretty good luck. My bike is stock with a Dyna muffler. I think a lot of people think they automatically need richer jetting when the change the pipe and air filter and that may not always be true. If in doubt, go back to stock (or close to stock) and try again. |

Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/14/19 at 09:15:07 Ohio Ok so I brought the bike to work. The bike runs great at half throttle just cruising. It was doing this really bad before I got into the carb and did updates. Now its still doing it but not as bad. When I 1st tore the carb apart it looked as though someone had attempted the white spacer mod but messed it up, so I m thinking I should just get the true spacer and try that. Also Batman said that the float height could be wrong, so I will check into that as well. And I had heard someone say that the ignition coil could be breaking down. Its 22 years old and it looks it too. whats your thoughts on the coil? |

Title: Re: looking for info on carb or direct fit carb Post by ohiomoto on 06/14/19 at 09:43:13 You are saying it pops and bangs when you try to go over half throttle? And this problem is happening no matter what jetting you had in there? Did, it run properly before the mods were done or did you get the bike in that condition? |

Don't know about the exhaust. Timing chain might have been installed wrong...timing is off. Some filters block the airports at the intake. If you slide shows signs of wear, it could be sticking which causes a very lean condition. The butterfly valve at the front of the carb opens allowing more air into the engine which creates more vacuum, which SHOULD raise the needle/slide allowing more fuel to mix with the air flowing through the carb. If that side sticks, you get a lot of air with very little fuel. It's hard to say without knowing the history of how it ran, how many of those mods were done at once, etc |

Title: Re: looking for info on carb or direct fit carb Post by ohiomoto on 06/14/19 at 10:00:16 Varsey pretty much summed up most of the problem areas. It could be electrical, I remember someone buying a used igniter off of me and it seemed to solve a similar problem, but would rule out the carb first. I had problems with my slide and it created some interesting problems that could easily be confused with plenty of unrelated issues. |

Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/14/19 at 10:46:14 ohio wow thats alot of info haha, lets see if i can answer all these You are saying it pops and bangs when you try to go over half throttle? YES And this problem is happening no matter what jetting you had in there? YES Did, it run properly before the mods were done or did you get the bike in that condition? OK ON THIS ONE ALOT OF MODS WERE DONE BEFORE I GOT THE BIKE SO I CANT TELL YOU, I DO KNOW THAT THE WHITE SPACER MOD WAS DONE WRONG. ok no more yelling haha on the filter, I am using the original black plastic pipe that came on it then that goes into the ryca 90 and then the filter. On the diaphragm slide it does look worn, I am trying to find a new one and not used. the things I am going to replace this go around are the choke assy because its bent, the white spacer,i am going back to it and the ignition coil. Its so hard to tell with me buying this thing used and it was not taken care of at all. Thats why I really wanted to just replace the carb with an aftermarket one But I cant seem to find one that even comes close to fitting correctly |

Title: Re: looking for info on carb or direct fit carb Post by ohiomoto on 06/14/19 at 12:43:22 Right on, so you really don't know when this bike ran properly and if any of the mods are related. FILTER, check. BENT CHOKE ASSEMBLY?? That could be an issue. SLIDE looks worn was an issue for me. (I got mine from partzilla.com) I would hold off on electrical stuff for now. Aftermarket carb, LANCER on here sells a properly jetted kit. The used bike that had some carb work done...make sure the air jets on to are the correct size AND I would consider buying a stock needle with the white spacer just in case they put the wrong one in. You want to rule out the carb, before throwing money at electronics IMO. Also helps if you tell us the year and mileage of the bike. |

Title: Re: looking for info on carb or direct fit carb Post by bbcwby on 06/14/19 at 13:29:38 Ohio you've been a great help. No I bought this bike and it was in sad shape, no fenders, flat drag bar, wiring was a mess, white spacer mod not done correctly and the tank was barely on. ( If I could figure out how to put pics on this thing i would show you before and after. ha ha, Yes the choke is bent and I just rode it home with it kinda propped open and it did a little better. Ok I get a slide on order and just go ahead and change it because I will be right there doing the reverse white spacer mod. I will hold off on the coil for now, and I am new to this site so I will try to find lancer as a last option if this 22 year old carb is just trash. I put stock air mix needle back in already. Ya sorry I didnt say year and miles but its a 1996 with 13000 again everyone has been so amazing and very very helpful. |

Title: Re: looking for info on carb or direct fit carb Post by batman on 06/15/19 at 20:02:44 Bent choke stem, it's soft brass ,you don't have to call on superman to bend back straight. nothing to lose it's already bent. The direct fit carb is the one you presently have, changing to an after market carb opens up a new can of worms. You've added a more open air filter ,an unknowingly tuned your intake by extending the passageway from the filter to the intake valve ( that's not bad, but it acts like turbo charging in some rpm ranges which can produce 4 to 7 % boost in fuel air flow) that and a less restrictive muffler ,increases air flow thru the motor , which requires adding more fuel , the stock jetting will probably be to lean. The jetting you ran after the carb rebuild was probably to rich, Your elevation is 951.65 ft above sea level , I would suggest 52.5/ 150 and 3 # 4 steel machine screw for the spacer mod(and retuning the air mix screw) as a starting point . Ohiomoto would probably not but his bike is stock. If you suspect the coil I would try electrical tape on the coil wire to the sparkplug ( there may be cracks) as higher speeds require higher voltages to jump across the plug gap.( you could run the bike in the dark and might be able to see if the spark is jumping to ground on the head . |

Title: Re: looking for info on carb or direct fit carb Post by ohiomoto on 06/16/19 at 06:04:11 My bike is a 96 with similar milage and the carb works perfectly fine. The only thing that I replaced was the slide, float needle, and a few jets for tuning purposes. And Batman's suggestions are fine, but I'm a fan of starting with stock jetting (and his recommendations are close enough to it) because you know it should at least run okay with stock jets, even with some mods. If you get a new slide, make sure you clean the carb body where is slides. Mine had some of the black coating from the slide built up on it. |
|
Title: Re: looking for info on carb or direct fit carb Post by batman on 06/17/19 at 04:43:46 And spray the black coating on the outside of the slide itself ,don't even leave a fingerprint on it. |

Title: Re: looking for info on carb or direct fit carb Post by stranglefoot on 06/17/19 at 16:51:25 Are you shure that the fuel petcock is ok? Our 650 savage did like this when the petcock was bad. Replace it with a manual raptor 660 fuelcock. Theese vacum operated ones seems to break easily. |

:o :o :o Very good point! I had to go back and read everything again and the OP never said anything about the petcock nor did we ask???? That's usually the first thing that gets pointed out. Hard to believe we all missed that. :-[ |

Title: Re: looking for info on carb or direct fit carb Post by LANCER on 06/18/19 at 07:36:45 Have you tried putting the petcock on prime and ride it ? If it runs well on prime you need to get a Raptor. |
