First of all hello to everyone here as I am new to the group. I just recently purchased a 93' Vulcan 750. I love it, and had just recentely taken it out on its first long ride. When I first bought it I had taken it on short trips, 20 or so miles.

Last weekend I took her out about 120 miles. She ran fine the first half of the journey, I was riding easy keeping her between five and seven rpms for most of the trip. On the second half I really opened her up, and for the first 10 miles she ran like a champ. Suddenly the engine shut off :doh: While on the side of the road I let the bike sit for a minute. She then started up after a couple of times, but not very strong at all. Rode the bike for another 5 miles, and she shut off again, after another high rev. Pulled over, let her sit and she started up again after a couple of tries. Noticed my gas was at a quarter of a tank, so I took the freeway to the nearest gas station and filled her up. After that I was able to ride home which was about 50 miles, without any problems. I did take it easy on the throttle. Does anyone have any suggestion as to what the heck the problem might be. I would really appreciate it.

Thanks,
Kevin

Did you turn your petcock to reserve at any point? Just wondering if the low-ish fuel was independent of the higher rpms.

Shoot, I didn't think to troubleshoot that way. I know that there was still a good amount of gas in the tank, as I could hear it sloosing around pretty well.

That was my first thought too, I hit reserve at about 100 miles which leaves me about 1.2 - 1.4 gallons in the tank. This usually shows to be in the vicinity of 1/4 tank on the gauge, probably just under 1/4 but you get the idea.

If that's not it, I've heard of a couple of people whose vent tube on the tank was plugged not allowing a free flow of gas to the carbs. Try cracking the gas cap and letting her breathe a little and see if that helps.

Good luck and welcome to the site.

Put some SeaFoam in the tank. While you have the SeaFoam in switch between Run and Reserve so the SeaFoam cleans out both tubes.

When you filled up, how much gas did it take? The gas guage is pretty hard to follow, but the odometer is more accurate, after a while. Now if you were hitting revs above 5k you are going to be sucking gas like it's going out of style, so it is possible you were just lower than you think.
Seafoam is always a good idea. Use it once a month for preventive maintenance too, about 3 oz to a full tank.
