Bike Died

I had a bad time on the Highway. I was riding home and had the front Cylender drop out like it ran out of gas. I had over 1/2 tank I switched to reserve and lost the rear Cylender. I was doing 70 MPH in the center lane during rushhour in Chicago. Not a good thing to hapen and pucker factor is high.
When I pulled over I looked for loose hoses found nothing. Switched from reserve to on, tried to crank it and she fired after a couple of cranks.
Rode the rest of the way home 40 mils and no problem.
I have a 2001 VN 750 with 12K miles.
Any ideas would be great

My '99 has done that a few times.

It seemed like it did it most when the battery was low on fluid. So I'd say that would be one thing to check.

Did you happen to notice a hissing sound from the fuel cap at all ? Might be a plugged vent.

One other thing that wouldn't hurt to do is clean the air filters.

Good luck with whatever ya do, and (I was only there once, but know how the traffic is) be careful on them Chicago roads !!

Nearly exactly the same thing happened to me when I bought my wife's bike and rode it ~70mi home. The only difference was that I am in the Tacoma area and I didn't pull over. I just stayed upright, clutch engaged and wound the throttle all the way out. Engine pulled me down to about 45mph then BLAP! I was doing 75.

I chalked it up to garbage in the tank. Ran a can of Seafoam through, at recommended volumes, and have gone 600 miles since with no problems.

Chronic problem?

The same thing happens to me too often. In my case, it is usually when the bike is warm and doing around 60. It acts like it in't getting fuel (or perhaps the mix is *too* rich). I have not been able to keep it running, but always wind up pulled over. Let it sit for a couple of minutes, and away we go.

I have heard hissing from the tank, but opening the cap doesn't seem to be an immediate fix. I still have to sit for a couple of minutes.

I wonder if it could be a stuck float in a carb or similar. I was wanting to try some gum-out, but not sure where to put it.

If anyone has any ideas, they would be greatly appreciated.

Sounds like you might be suffering from vapor lock.

Many here use "SeaFoam".
I haven't myself yet, but someone here could probably leave a few helpful words on how best to use it.

When mine does it, I have tried opening the cap, but it usually doen't make a sound.
It seems like if I can catch it at the first sign of any spudder, flip to reserve,
cruise for a bit, then flip it back over, everythings fine.
I'm kinda used to doin' that now.

Wouldn't hurt if I'd check the petcock, just haven't got 'round to it.

Well I drained the carbs and got a little dirt, not to bad. Replaced the Battory with a Maint, free (I know should have done it before). Adding a Volt gage today to watch the electrical system.

Ok,
Seems to be a pretty common thing. My bike does it, and it's an '05 with 4300 on it. Exactly what is seafoam? Some sort of fuel system treatment?
