My bike (07 695) has been having intermittent issues with sputtering to a stop. This mostly happens when the bike is already warm (but it di it cold this morning). I would be out riding around the city and all of a sudden following a pause and go at a yield or stop sign, the bike would sputter and cut off. The first 2 times, i let it sit for a bit, opened the tank thinking it might be air intake or something, and it started up again after 5 min or so. The last time it refused to start. But once it got to the shop it started again. I first thought it was the fuel pump/line starting to have intermittent issues. But after having a tech put it up on a lift and jiggle some wire around while it was running, we were able to replicate the problem---- he had it die on him while on the lift and got an error code for the O2 sensor apparently.
Replaced the lambda and rode it back home without an issue. Got it wet on the way home. Rode it the next day without an issue. Then yesterday while riding down the road, it did the same thing. again while warm (~155deg). Let it sit for a while.. checked some wires and tried again, but to no avail. Later -- opened the tank and it started up (2 times). But then this morning it wouldnt turn over. Opening the tank didnt help.
My next culprits are ..
1. fuel pump
2. injectors
3. fuel line
4. other shit
anyone have thoughts on how I can test any of these individual parts?
Thanks
While changing the fuel filter look for fuel contamination. More than likely, the O2. code was thrown because of the stalling.
Did you let it sit for a long time (i.e. over winter). Have you done valves lately?
Specify what rpm's the bike has died on you. Idle?, 2-3k? 4-5K? That will help diagnose a bit better.

Will get on top of the fuel filter change and see what happens following that.

the bike sat briefly over the winter. But has been ridden since march. Havent checked the valves -- but the bike is getting close to 12K miles.. maybe time to check.
It usually dies out ben 2-3K rpm. But today I had it not even turn over when cold.

ha.. been laid up with an injury -- gonna have to have someone else do it now. then i can [Dolph] with a broken leg again.
I posted with a mystery problem regarding a Sport 1000 that wouldn't idle, recently, and its problem sounds similar to your bike's. The bike idled very poorly cold and not at all hot. We checked spark plugs, O2 sensor, stepper motor (idle air control), throttle body passages, charcoal canister (it was still mounted and hooked up properly), battery voltage and charging system, and the valves (just in case one was WAYYYYY out).
After a week of fiddling, it turned out that the factory synchronization settings were off by over a foot of water column. Synchronized the throttle bodies and now the bike idles great!
It's usually the simple things. Duh. [bang]
As for idling. I will add that my experience has shown that vavle shims that are too loose tend to result in poor idle when cold and smooth out a bit when warmed up.
Valves shims that are moderatly tight tend to idle better cold and get choppy when the bike is warm.

Hey, Scott, how are ya? My 695 is doing exactly what deepok8612's was doing. Can I synchronize the throttle bodies myself? I have only started to troubleshoot the problem. Cleaned the air filter and checked my lines to see if any were pinching. Got on here today to see what other folks are doing with the issue. I thought it might be corrosion from the dampness of the area. Never had the problem in Colorado or New Mexico. Hopefully, you will see this. I know it is an old thread, but new to me. Thanks!
