'98 Softail starts, idles, ride for 5 min then bogs

Worth a shot on here:

98 Softail Custom with 7,500 miles
80ci Evo Big Twin
S&S E carb
Dynatek Ignition
Dual Spark

The Bike starts right up, idles fine, sounds fine, both cylinders firing (heat off both pipe exits) and rides fine for about a mile and then starts to bog like crazy. Plugs, Coils, Wires just replaced, same thing. Dynatek checked, on correct settings. Plugs not fouled and correctly gapped. She's carbed so it's not like she's doing this after coming off high idle. I'm at a loss on this one. If she shuts off after starting to bog and is restarted a minute or two later, I can get another mile or so before the bogging starts back up.

By bogging, I mean under load, 90% of power cuts out, I can nurse her along at 15-25mph by kicking the revs up to 2,500 and easing out the clutch but something is clearly off.

Let the HD bashing begin.

Haven't checked the first two. Can probably find fuel filter online and the choke works fine, helps to start her up when it's cold but still holds an idle once warmed up and choke off, so choke seems to function.

How would I test for an air leak?

First make sure that all of your clamps are tight . The ones between the carb and the head . The second way is to spray carb cleaner in those areas while you have it running , listen for a surge , that will ID the air leak .

Flooded.
Bad needle at the float.

the petcock keeps things in check while she's off and float lets the fuel level get a head of the carb while running.

could definitley bad gas. i had a hell of a second half of the season last year because of a bad tank. kind of had the symptoms as your harley

would start ok, then after a mile or so, would idle like crap to the point that it felt like it would die.

check your filter and pump.

good luck, bri

Get into the carb, I nice cleaning and rebuild would help. first place I would be looking is the float bowls to make sure they are adjusted correctly. Every else's suggestions make sense but they don't account for the running fine for a while part.... then performance going downhill. I'm guessing floats are set too low and your running out of gas so to speak, while it sits, they fill back up. Or like Vcook said, pop the gas cap and make sure its not vapor lock. that's the only other one that makes sense.

could be that heat is affecting the electrical components once hot. i had an issue like that once. once the stator got hot resistance would increase and the spark was too weak to properly jump the gap, resulting is a very rich condition. but u say its not fouling plugs...just thinking out loud here i know how this kind of shit sucks. hoping u get it resolved soon.

I had this same problem on my zx7. I ore everything apart trying to chase it down. What I started was at the tank and worked down.
Drained the tank. New fuel. Same prob. Next.
Checked the petcock. All was fine. Next
Found the screen to be clogged. Cleaned. Put back in. This time I got 3 miles from home and had same prob show up. Turns out the tank had internal rust be ause I took it all apart again, and the screen was clogged again. Had to yank the tank completely off, drain it. Let it dry out for several days. Then shook upsidedown and used an air hose through the lines to blow out all the bullshit sedement. Took several hours to do so. If the screen had anything in it, yank the tank. it's a bullshit time consuming way, but only way to figure it out and saves $ & time chasing anything else right now.

...plus my gf was with me saying "omg slow down, slow down" and I was thinking "Lose annoying squalk box in passenger seat, afford more mods and have less weight in the car and on the back of the bike"...so i dumped her and I'm single again as usual...HERE KITTY KITTY!!!

U will never know there is sedement in that tank til it's drained, off the bike, and shook upside down. Even shaking it normal side up, doesn't always show the sound. It has to upside down, and with the filler cap OPEN so the air can get to it.

Due to HD's beautiful dual view gas ports (second cap comes off), filter looks clean as hell and petcock (while chrome aftermarket bullshit) also appears clean/clear w/zero rust. I'm going to try new fuel tomorrow, see if that straightens her out. Real low fuel level now that probably doesn't help things (aftermarket petcock doesn't have reserve setting, AWESOME AFTERMARKET GEAR PREVIOUS OWNER!!!).

I doubt it's the carb as she only has one carb for both cylinders - correct me if my logic doesn't jive though.

Thank you very much for the input everyone- hopefully I'll get this tracked down!

One carb makes more sense if you cant blame just one cyl.

also with one coil as many have you cant blame that for one cyl. until the plug wires.


Try this, as she starts to stall turn the flow from the petcock down if she cleans up her act with less gas there ya go.

I'll start by saying I know shit about HD's...

Sounds like you're starving of fuel, like Blarney said maybe a bad vent on the tank? Starts off good, but as fuel drains, and the vacuum in the tank grows it gets worse and worse. Did you try running it with the cap open, or opening the cap as soon as the problem begins?

Perhaps pull a plug and post a pic, let one of our experts "read" it for you.

OK all of you starving for fuel guys.

Riddle me this when the machine is cold she likes the extra fuel.(Choke) when she warms up what does the system like??









Less fuel (choke or enrichment)off

When a machine starves of fuel it just runs out of power.

A fat condition drowns the bike in the above described manner.



Check the float needle for obstruction.Prevents closing.
Just my 2ct and wont push the advice any farther.

plus he said he clutches it to keep it going. puts a load on the motor so that it actually uses up more fuel for a moment. think everyone assumes just because he said bog it means lean. or because more fuel means more powaarrrrr lol

also i didnt see anything about if this bike is a new acquisition or not(maybe i just am blind) bike u just picked up and dealing with this problem? or a bike u had and this is a new problem?



of course it could be any number of things, but as suggested u will have to go through the carb and inspect everything. like said may be a bad needle/seat. but sometimes that would lead to overflow and u would see evidence if its a gravity feed and petcock is left open.

if the bike is new to u then u would have to verify that the previous owner didnt do any strange jetting. or maybe the dude weighted 600 lbs idk. one other thing to keep in mind idk about the carbs in these bikes but most main nozzles are brass and needles are a harder alloy. so overtime as this is an old bike the needle wears on the nozzle, causing it to become a much richer size. to the naked eye it can be undetectable but they get ovaled. this could contribute to the problem. it may be a few small factors that are leading to a bigger issue. again just trying to brainstorm.

another thing is if u are riding it try and figure out what portion of the throttle u are having issues. seems to me like maybe not under a 1/4. try to see if u can narrow down where.

If that were the case wouldn't it never shut off fuel? Like if he parked it overnight with the petcock open it would dump fuel all over the garage floor, catch on fire and kill the neighbors kitten sorta thing?

I only argue because I had a similar(ish) situation that was dirty ass petcock, it wouldn't flow enough fuel, it could start and idle, but couldn't keep the bowls full during any other situation, unless you shut it off and let the bowls fill back up, then it ran OK for a bit before going retarded.

I am probably completely wrong, but that's what the internet is for right?

All advice seems sound, Make sure your air filter isnt saturated. They like to get funky under that cover, specially if its not running right.
