Title: Nice day for a ride...if she would quit stalling! Post by skatnbnc on 02/03/08 at 18:52:05 So it was warm enough to take a pleasure ride instead of the daily commute, but I had a funny thing happen on the way to the forum this afternoon. Temps 55F, bike full of gasoline, happy trail plan to Beaufort from New Bern (three hour total roundtrip). Been starting with the choke at setting two with the cold weather and had no issues starting up or running. Until about halfway there when I was in thrid and shifted down to 2 for a stop sign. And realized I was riding a silent motorcycle. No throttle. Hmmm. Coasted to the side and checked everything. Tried multiple times to start. Starter fine, battery fine. No turnover. Sat for a few minutes. Tried again, and it started up sluggishly. I rode to the next gas station and filled up because I was a little low (but not major). I could find nothing else wrong. Over the course of the day three hours of riding, the silent stall (no backfire, no pops, nothing) happened a total of four times. Each time was at a a light or stop sign. I was never in first gear, but was either downshifting or coasting (slowing) with the clutch in. I tried various choke settings and none made any difference in getting it started back up. Each time I had to wait a minute or two before it would start. Sooooo...my guess is the idle speed is off. Do I need to adjust the idle screw, and if so, do I set it more in or out? |

what does no turnover mean ? it did not start and run or did not spin when you tied to start it? |

That would be my guess too. There's a black plastic knurled knob on the side of the carb. Turn it clockwise to raise up the idle a bit. Adjust the slow mixture screw to get the best/strongest idle with your bike warmed up. Clockwise -> Lean. Counterclockwise -> Rich. In cool temps your bike runs leaner. I'd richen it up. |

Title: Re: Nice day for a ride...if she would quit stalli Post by skatnbnc on 02/04/08 at 05:21:58 When it stalled the first time, I set it to RES because I thought I had run out of gas. But it was not empty, and on RES it still took several tries to start up. By 'not turning over' I meant that the ignition clearly engages, and the lights work fine, and it "spins", but the engine does not catch. Like an old car trying to turn over....zzzzznnnn, zzzzzzzzzznnnn. (don't you love trying to describe a noise in text?) ::) Dynobob - I will try that this afternoon at lunch to see if it helps. Main thing is that I am back to commuting this week and it may be awhile before conditions duplicate to repeat the stall problem. Yesterday the stalling happened after the bike was completely warmed up. When I ride to work, its a whooping 4 miles - no time to even make toast on the the pipe. ;) |

Title: Re: Nice day for a ride...if she would quit stalli Post by Reelthing on 02/04/08 at 06:37:12 Ok, so it dies when you pull the clutch in after it’s warmed up and will not start back up for a couple of minutes. When first trying to restart it is the choke being used? This seems to describe a very lightly flooded engine – as already suggested above a slight mixture adjustment (the brass plug has been pulled?) like a 1/8 turn in or less and a little faster idle may cure it – unless something else is going on like a dirty slide. Without a tach one way to hit the idle pretty close to where the engine likes it is to let it idle in the dark – watch the head light on low beam – set the idle just a fraction above where the light dims |

Title: Re: Nice day for a ride...if she would quit stalli Post by Savage_Greg on 02/04/08 at 06:58:15 Well, it won't be the idle screw. That doesn't change itself. If it idles correctly once, it should idle correctly all the time...unless you caught a little gremlin and he's playing with it :) Anyway, it should not be idle speed. Especially since you don't have to adjust it to make it start again. Is there anything that you've done to the bike lately? I assume that you've looked it over and don't see any loose hoses, right? I agree with Reelthing. Does sound a bit rich. But this happens with a closed throttle situation as you are coasting or slowing to a stop, right? Are you riding with the choke on at all? |

[/quote] If you'll notice, the idle screw has a spring on it. That is what prevents it from changing adjustment (the idle mix screw has one too). Is it possible that you have the idle speed too low? Stinger was always complaining about the same thing happening to his bike. He'd ask me to test ride it, and always, I have to turn the speed up. He'd just say that he liked the sound that way, and after he'd leave, he'd turn it down again :P Try turning it up just a little bit... (Hey, Stinger! Where the hell are ya, anyway?) |

Put blue Loctite on some of those bolts. Loctite is your friend. It'll keep parts from falling off as you go down the highway :) |

Title: Re: Nice day for a ride...if she would quit stalli Post by bill67 on 02/05/08 at 03:21:55 You might be getting a lot of condensation in the gas tank and carb with the colder weather and it warming up when you ride.I would put some seaform in the gas tank,it will get rid of the moister in tank and carb and lube the slide in the carb. |

Title: Re: Nice day for a ride...if she would quit stalli Post by skatnbnc on 02/08/08 at 09:39:45 I'm sorry guys - it's been a zoo at work, and I've been riding every day, but not getting home until after dark, so I've not been able to try ANY of the great suggestions yet! :P Yes, I want to do lock-tight on the dang windscreen bolts - super! And I cannot find the black knob on the carb that was mentioned - where exactly is that? Can one of you tell me (in a few simple steps) how to make it idle a little faster and I will try that at lunch today. Should I turn the brass screw or something else? |

My '01 idle screw is not black, just metal. Ok, on the petc0ck side of the bike, look at the carb. You should easily see the choke knob and the throttle linkage. If you give the throttle a twist you should be able to see it move. When it returns to "no throttle applied" state, look at the area it's stopping. You should be able to see a little screw with a knob for a head (vesre a slot or phillips head) that is the Idle adj screw. Turn one way for slower idll, turn opposite for faster idle. Idle is dependant on multiple things two of which are outside air temp and engine temp. For colder weather you may need to tweakl it a tiny bit. |

Title: Re: Nice day for a ride...if she would quit stalli Post by skatnbnc on 02/08/08 at 11:43:19 Well I stalled out AGAIN today at a light on my way back from lunch. I had gone to Wallyworld to get some Seafoam (which they did not have). [smiley=thumbdown.gif] Once again, the conditions were the same. - the choke was pulled out (because of the cold) - I had been riding for about 3 miles So with photo in hand (thanks Greg!) I will go out in a bit and turn the special screw to adjust the idle speed and see if that makes a difference. Thanks guys. :) |

Not too much, now. Just see if it helps. But really, in cold weather 3 miles is kinda short to expect it to be very warm. How about your clutch adjustment? Is it correct? (Yes, there is a photo in the "Frame" folder...) |

Title: Re: Nice day for a ride...if she would quit stalli Post by bill67 on 02/08/08 at 13:01:45 Skatmbnc the owners manual also shows where the idle speed screw is. |

Title: Re: Nice day for a ride...if she would quit stalli Post by meck on 07/08/08 at 10:13:29 I'm having this same problem and I was wondering what the final outcome was. When I pull in the clutch and coast for a bit, the bike will silently stall. It generally starts right back up, but it is happening quite a bit. |

Adjust the idle up a bit. Maybe you can get a friend or the dealer to stick a tach on to check RPM's. I have a tach and I do have to adj the idle if the temp changes. (say from riding in 65 deg F waether to riding in 85 deg F). |
|
Title: Re: Nice day for a ride...if she would quit stalli Post by meck on 07/08/08 at 10:27:59 I did try bumping up the idle. It definitely sounds high (no tach yet), and it does lessen the problem but it hasn't gone away. I think my next step will be to lean out the mix screw 1/8 turn or so. |

Try to find the center of the mixture screw setting. Turn it one way till the idle drops (best to go clock-wise (in). Then, while counting turns, turn the other way, thru max RPM and till it drops again. Then set the screw to the rich side of center between the two. You may need to make it slightly richer if the backfire comes back after adjusting.... |

Title: Re: Nice day for a ride...if she would quit stalli Post by meck on 07/08/08 at 18:21:39 I tried adjusting the screw but honestly I couldn't hear a difference in RPMs. So I went with the "adjust till it's fixed" method. I gunned the throttle and let it snap back. Where it was originally, the rpms dropped to where the bike almost stalled. I leaned out the mix until that went away. I kept turning clockwise until I got a backfire, then backed it up between those two points. After a 20 minute stop & go ride in 95-degree heat, no more stalling. I'll see how it goes on the commute tomorrow. |

Title: Re: Nice day for a ride...if she would quit stalli Post by meck on 07/16/08 at 13:54:19 It was working fine for a few days, then the stalling came back. Generally it is after I am holding the throttle at constant speed for a while, then slow down eventually to a stop. I have already bumped up the idle speed with no effect. I replaced the vac line from petcock to carb and it seemed much better, even after a longer ride. Then today I was riding about 8 miles at a constant 40mph. When I went to slow down for a turn, the engine bogged way down, nearly to a stall, then a HUUUUUGE KAPOW backfire, then it stalled. This happens with the petcock on ON and on PRI. I went back and tried to readjust my idle speed and my idle mix, but I haven't gone riding again yet. Any other suggestions? I am supposed to be making a longish (60 mile highway speed) run tomorrow afternoon so it's getting to be crunch time. BTW, it does seem to be much worse in hot weather. Last night after I replaced the vac line it was about 75 degrees... now it is around 95. |

Title: Re: Nice day for a ride...if she would quit stalli Post by mentaka on 07/20/08 at 16:26:03 Hello, Dont know if your still keeping trake of your post but i gotta suggestion for you. Cant say this is gonna be the problem or even work but fingers crossed it seems to have done the trick for me for now as i was having exact same problem. Breather tube. Take bung off and empty it. Sounds simple and maybe a little stupid but ive been having same problem as you on and off for about 6 mths. One day decided it was time to check breather tube and empty it if needed and like i said so far so good. Hope this helps. |
|
Title: Re: Nice day for a ride...if she would quit stalli Post by meck on 07/21/08 at 08:27:38 Do you mean the blow-by tube from the engine to the air box? There was nothing in there. Or, did you mean the capped drain tube under the air box? That is empty as well... |
|
Title: Re: Nice day for a ride...if she would quit stalli Post by mentaka on 07/21/08 at 10:35:52 It was the breather tube with the cap. Shame that didnt work, as i said it seems to have done the job for me. |
|
Title: Re: Nice day for a ride...if she would quit stalli Post by meck on 07/24/08 at 08:22:33 Looks like I found it... it was the petcock. I had the thing apart and the diaphram looked good - I gave a little suction on the vac port and didn't feel any leaks so I figured I was good. The fact that she was still stalling and bogging while on PRI also threw me. I took the petcock off again, did the mod to manual and it's nice and smooth now. |
