I have a 2007 Yamaha Royal Star Tour Deluxe with just over 33K miles on it. Today I was out riding around in the local area, run a few errands, visit dad at the home, stop at a body shop about a project I have. I had stopped in a small town for about a half hour and I headed east out of town. Speed limit went from 35, to 45, to 55.
I was in 4th gear as I approached the 55 MPH zone so I sped up to 55 and shifted into 5th (high) gear.
In less than a hundred yards the engine died. I coasted a little ways and then managed to turn in to the driveway of a small business. I sat there for just a minute wondering what the heck had happened now. I checked the kill switch. It was still in the run position. But I flipped it back and forth a couple times anyway. Checked fuel petcock, it was on, choke was off, over 1/2 tank of fuel in the tank. I then shifted it into neutral and tried the starter.
The engine turned over just like it normally would but didn't start right up, like it normally does. After maybe 3 or 4 seconds, the engine started firing and then started running normally. I revved it up a couple times then let it go to idle. Then I shut it off. Turned the key back on, hit the starter and it fired right up, like normal. Rode the rest of the way home, about 5 miles, and it never missed once. Temperatures were in the upper 80's or lower 90's.
This bike did nearly the same thing 2 years ago right after I first got it. I was in Colorado and was coming through LaVita Pass, (LaVeta?). I had came through the pass and was on the downhill side when the engine died. I tried starting it several times while coasting down the hill and it wouldn't start. I finally gave up and just coasted to a stop on the side of the road.
I got off, checked fuel, choke, plug wires got back on the bike and it started right up. Rode from Colorado back to Arkansas and it never missed once. When it quit in Colorado, after talking to other riders and the dealership, the suspect was just the altitude caused it to die. Now I'm not so sure.
When I got home I parked the bike for about an hour . I got to wondering if my fuel pump had quit temporarily on me. When I turned the key on, I could hear the fuel pump, pumping up pressure, and the bike started again just like it normally would.
Before it died, there weren't any warning lights coming on. Anyone got any ideas?
