First problem I've had with my 05 DL650. Bought it at 8,000 mi and it just turned 10,000.

Had a beautiful Sunday ride in the Tennessee countryside. Absolutely gorgeous riding. This is why I got back into motorcycling. Wee ran flawlessly. Got further away from home than I meant to, so I cut across some more country roads and found I-65 north to Nashville. I don't get on the interstate much and rarely get much past 65 mph around town.

Rode an indicated 85 mpg for about 25 miles, smooth as silk. It was fine. Got behind a 16 wheeler and it started cutting out. I didn't believe it at first, thought it might be severe buffeting from the truck wake. Took her down to 70 mph, behind the wake, and she was still cutting out. Back up to 85 and it smoothed out and I passed the truck and it rode smooth as ever.

A few miles later, at about 75 mph indicated, had an interstate incident. I was in the right lane, about 8 seconds back, when the cars in front of me all lit up red. Cars and minivans were emergency braking so I did too. Went from 75 to 35 in two pumps, each one ending when the rear wheel started dancing and trying to come around front. Slowed down real fast. A minivan swerved off to the shoulder on my right, braking hard, and the cars in all four lanes were all braking hard too. Then a deer jumped across the minivan and on past the shoulder. We all resumed interstate travel. Bike ran fine.

Five miles later, I took an exit to Brentwood and downshifted to engine brake on the exit and the Wee died. That was a shocker. Turned the ignition on/off a few times and the center red light was on. Checked the kill switch to make sure I didn't accidentally bump it. No joy there. I turned the ignition on, big red light, hit the on switch, then starter...and it started right up.

Rode it smoothly all the way home. But now I have lost confidence in the bike. What in the world happened? Could the sudden deceleration just a couple of minutes before have caused the Wee to die when I slowed to take the exit? Is the earlier cutting out related?

Recent additions have been a bash plate and center stand, but they went on smoothly enough. Gassed up with Exxon regular (with 10% horse urine). This bike has never had a hiccup. I really don't want to take it to the local dealer, but I will if I have to. :confused:

Can you-all suggest a possible cause? Had some rides planned but now I don't want to get too far from home until this is resolved.

Thanks,

Spooked Motofan

Possible corrosion on the kill switch contacts. Maybe I missed it, did the starter not turn over until you fiddled with the switches? If the starter did spin over I would think water in the gas.

Whenever the engine isn't running, you'll get a red light. It's an oil pressure light and the oil pump doesn't supply any pressure when the engine isn't running. It could be something as simple as water in the fuel. See if it still happens on future tanksful.

I have a Burgman 650 that the headlights stopped working after a short stop 80 miles from home. Had to ride home with no headlights (daytime). The bike ran just fine. After some troubleshooting I found the start switch wasn't making contact in the off position which completes the headlight circuit. After flicking the start button a few times it cleaned itself enough for the headlights to come on and have worked fine ever since. The only reason I mention this is because this happened after washing the bike and evidently some water got in there and caused a bit of corrosion on the contacts. The kill switch I would think could be subject to the same possibility as it completes the start circuit with normally closed contacts.

Not sure what the problem is, however we are fortunate enough to have a very good Suzuki tech here in Nashville. Ray Davie at Yamaha-Suzuki of Cool Springs is very, very good. He's worked on mine for 3 years and I've never had any complaints whatsoever.

It could be a number of things but it's usually best to check the simple things first.

My first thought was the same as Greywolf's: water in the fuel. The hard braking and turbulence behind the truck could make the water move around and make the problem worse so it fits. Add some water remover, fill up a different (ideally Top Tier) Gas station that does a lot of volume.

I think something in the air-filter box could cause a similar effect so it wouldn't hurt to check there as well.

If that doesn't fix it I would be inclined to check the simple electrical connections like battery, the clutch cut-out switch connector, the side stand one, and that fuses are properly inserted.

Scott, are they part of the Honda Cool Sporings bunch? Not having any joy with the Honda side at all right now. They ruined the motor on my Nighthawk 250, which was cherry. Very not happy with them. Zooki side is SUPPOSED to be different than the Honda side.

I need someone to talk to about it.

Good starting places. Hope it's something as simple as this.

given your milage and the age of the bike it has seen very little use

if it has sat for a long time run a few tanks of fresh gas through it, and change the plugs out diying at quick stops, and hard cool morning starts are a sign of worn plugs in the sv motor, esp if the idle is set to low.

Has all the scheduled maintenance been done?

I don't mean to sound like a broken record on this point, folks; I'm just speaking from hard, embarrassing experience.

Yes, they are the same overall company but different individual companies. I've dealt with both and have not had any complaints. The Honda side does the maintenance on my VFR.

I'll ask for Ray on the Suzuki side. I'm having a big issue on the Honda side right now and am not happy...yet.

Thanks, vdum, greywold, scraig, V-Tom, uzidzit and dtalk;

I had just filled the tank at an Exxon. The bike had not been ridden for 7 weeks. I will try a gas additive. Could be electrical too. Cutting out felt maybe like bad fuel. But when it died on the interstate exit, I had downshifted and expected it to kick back in. Never did. That sounds more electrical.

You've given me some good starting points and advice. Thanks all!

Seeing as a bash plate was installed, check your side stand switch and wiring.
Too, check your spark plug caps.
Thought about the bash plate and side stand switch. Will check plug caps tomorrow.

Thanks.
