Not sure if I'm posting this in the right section, then again I don't know the problem so I guess here is a good spot.

So here is the story, I was cruising along a flat straight back road at about 50mph, mind you it is probably the only day in New Hampshire when the temp reaches 95deg, so I was cruising along running good when all of a sudden it seemed as though the motor wasn't getting any gas, though the gague says half tank. It started to bog down on me....I thought WTF! So I switched it to RES really quick and it got me another 400 ft or so, then it quit. Again, WTF! So I first made sure all of my wires were on my plugs, which they were. All good there. I had a half tank, looked in to make sure I still had some. So I tried to start it, no luck. I sat there for about 1 min to let it cool. Tried again, nothing. So I pulled back on the choke all the way and she fired right up. I let it sit with the choke open for a few seconds and then switch it closed. So now it's idleing fine and seems to be running ok. I went another half mile and filled up the tank completely to make sure that it wasn't that. I let it sit and cool down for 5-10mins and then she fired up and started no problem, like it always does.

So....now it seems to run fine, but it seems like I'm pulling a ton of dead weight behind me....maybe it's in my head.....runs fine....at the same RPM's as it usually is....gets up to speed fine and cruise great as always, just doesn't seem as snappy? Maybe?....is it in my head? Or is this just an isolated incident like I'm hoping.....any help would be greatly appreciated.

Thanks guys and girls!

I think your bike said, "I'm in New Hampshire and it's 95 degrees! WTF!" and quit. :pepper:

Folks have been posting lots of similar things, but it sounds like some crud broke loose and clogged a fuel line; and then freed itself and you're good to go. Give it a good dose of Seafoam and see if it clears your head...and your bike. :) Seriously, there's so much junk in the gasoline anymore it coulda been anything - and if you're not seeing any change in performance, you can probably relax...if it happens again, then, well, two points make a line. But for the moment, I'd take it as a blip.

Getting any rain up that way? We're cooking down here.

Same thing happened to me on Monday on the way to work, But I didn't switch to reserve until it died with a huge backfire. Coasted to a safe place to pull over on Rt 20. Checked the gas visually yup there was a half tank there. switched to res. hit the starter nothing hit the starter again fired right up. Everythng was fine the rest of the way to work. The next morning after work started up fine. And every chance I could I got oh it pretty hard.

Hey Cindy! Long time no talk huh?! Yeah, I swear were in Seattle, New Hampshire up here. Everyday has been either overcast or raining, it's never been like this here. But today was a scorcher here, gross hot. Yeah, I think it's safe to say that your right Cindy and bj31702, just happened. Crud probably did fill the lines and clogged it....no biggy. I poured in some Seafoam to let it sit tonite and probably tomorrow...might rain again! So we'll see how it goes. It's weird as every other tank or so I put in more Seafoam.....weird.....Thanks for the quick responses guys and girls!

Sounds to me like "Phantom VN750 Failure"... Had this a lot in the early days when it was hot as a monkeys ass and the bike was working HOT. Believe it or not, it turned out to be my RR, which was in the early stages of failure. It would get real hot and it's preformance would start to drop.

Well I'm hoping it's just the phantom VN750 failure.....It would make sense that it may be the heat because it is never this hot here. I'm hoping....I'll be purchasing Bulldog's famous R/R bracket very soon so I'll cover my a$$ there. Let's just hope thats what it was. Thanks!

Since I've just put McKnight back together...do elaborate as to what 'working hot" looked like. You mean the bike was running warm, as evidenced by the temp gauge? Or there was a lot of heat coming off the engine block? It's monkey's-butt-hot here, too - right now I have a 45-mile one-way ride to work; in the a.m., gauge is nice and low, and I'm wishing for some warmth off the block. In the afternoons, I'm shutting down at every stop light, the gauge is running right in the middle of the temp symbol while cruising, and my right leg is hot. Just the right, not the left. No overheating, though, and no untoward behavior by the bike...just me, fretting. Kinda like Tyger. :)

What you people call hot is just another warm day here. Mine has done it several times, no real pattern except half tank or less.

Yeah, like I said I filled the tank up and it seems to be fine...I rode the remaining 30+ miles home no problem.....weird....Though it never gets that hot here so I'm not really worried.

Cindy, it was running right dead center of the gague.....highest it's ever been really, even sitting in stop and go traffic. I would definitly say that it was probably just the heat....which is weird.....Thanks for all of the help! Just wanted to make sure it wasn't a big problem!

I've been out on more than a few 100 mile+ rides where I'd have the "Phantom VN750 Failure" once, and only once, during the entire ride. Sometimes at the start of the ride, sometimes towards the end.
Seems like no rhyme or reason to it. It just happened. :confused:
It always seemed/sounded like the bike was only running on one cylinder when it happened.
On the Erie ride (450+ miles total), and now that I think about, for the last several months, it hasn't happened at all.
I don't have a relocated R/R, but also don't have the goats belly. I do still have a wet-cell battery.

It must be caused by some newbie Gremlins that don't know how to hold onto the bike yet.
They just start to cause a problem, then fall off!
Damn Gremilins !!!

Back in the day when my VN750 would die for no reason, the conditions were stop and go traffic in 85-95 degree days. Heat rolling off the engine like nobodys business and the fan going constant. I had a RR die on me and after it was replaced along with the battery the bike never died on me for no reason.

All the times after that there were reasons... :)

I have not had this happen in about 8 years now, so I guess that either replacing the battery or the RR did the trick. Or both...

Look at both your battery and your regulator. The RR when it starts to fail will short out in the heat and let the bike die. And if your battery is kafunky, the heat rolling off a nice and hot stop-n-go engine will do you not favors either. With your RR relo kit coming, now might be the time to look at finding a replacement RR too.

Ya know, my PC at home does that a lot (does something kerfluey for no reason), and I've had the bike do it occasionally. But, really, I'm taking gremlin bells with me on my next Southwest Airlines flight! :wow:

Reading through all these posts, I got to thinking back to last year when I was on a benefit ride in stop and go traffic in about 90º temperatures. My bike sputterd, seemed to run on one cylinder and died frequently. It was doing what y'all are talking about! At the time, I did not have my R/R relocated, so I know I was cooking it.

I stopped to get gas on the way back and the problem seemed to go away. I thought that was really odd. I kept waiting on it to do it again thinking I was going to have to try to troubleshoot one of the 'random' problems. Guess I know what conditions to look for (and avoind) now!

Thanks!

Bulldog, I am excited to get my R/R relocate package from you as I am sure that I haven't done good to it. Though it doesn't get to hot here so I wondered if the same applied here? That is probably the hottest day we've had here since sometime last year when we went through a short dry spell. Today is supposed to get up to 80 with some scattered clouds....I'm taking the wife out on a spin so we'll have to see how she acts today. I did notice that a lot of people have been saying that this only happened to them when they had a half tank or less or fuel.....weird......any ideas there? I make sure that my tank is usually always full.......I'll have to make sure from now on. With the R/R relocate kit I'm sure it'll save what's left of the R/R if I haven't fried it already. Oh and my battery is new this season. I only got this bike at the begining of this season, so the guy who owned it before put a new one in for me before I bought it. Looked at it....seems fine.....R/R seems fine as well......Thanks guys!

That's what was strange about mine stalling out like that. A couple of times it was at the start of the days ride, less than 5 or so miles from home, and on a cool ,maybe mid-upper 70's, morning. So I don't think (mine atleast) was very much heat related.
The only thing I've done recently that might have something to do with not having the problem recently, was replacing the stator. But the last couple of times I remember it happening was well before my stator went kapooie.
As for how much gas there may have been in the tank, I have no idea now.

Oh yeah, I can see you trying to explain that to the TSA goons at the checkpoint. :smiley_th

Cindy: "You see, this is actually a safety device to keep evil gremblims from hanging on the wing of the plane."

TSA: "Yes maam, please come with us. Hey Helga, get the gloves!!! I've got a live one for you!!!"
