Would bad gas (or water in the gas) prevent starting?

[Rob H]

Not to sound dumb... but my Hyper didn't start this morning, and I'm grasping at straws here.

The bike just had its 7500 service a couple weeks ago and got a clean bill of health. I rode it to and from work without issue for two weeks. I gassed up Friday morning, rode to work and back home, and then parked it for the weekend. I tried to start it this morning, and no go. It cranks like a champ, sounds like it wants to start, but then doesn't. I tried about 15 times before giving up and taking the car.

Would water in the gas completely prevent it from starting? I'm thinking of dumping the gas (once I figure out how to do that) when I get home...

I'm open to any suggestions!

Thanks!

Have you checked the fuse for the fuel pump? Maybe when you turned it on this morning it popped it. So she'll crank but not fire.

That actually makes more sense. I'll check. Thanks!

Fuse is fine. Still not starting... >

1.pull plugs and check for spark
2.could be tps out of whack
3.valves to tight
4. are the injectors firing? on some cars you could hold throttle wide open and it would make it fire up

i had bad gas two yrs ago in a bike and it would start but would stall out,happened twice from same gas station so i stopped going there.
sucked trying to figure that one out and i thought i killed my bike

I'll have to give it another try tomorrow night. The battery needs to charge after all the attempted starts.

After reading about a million posts, I tried whacking the throttle while holding the starter button. It would actually get to a rumbling idle for a few seconds and then die. A couple of times it seemed like it was going to keep running, but no luck. I tried holding the throttle wide open as well, with similar results. It would rumble for a little while, then die.
I also tried turning my Fatduc to full lean (as someone had a similar problem that was caused by the Fatduc), but it didn't help. I'll pull a plug tomorrow night to check for a spark...

I did shake the bike for a while (I must have looked like a maniac) to stir up the gas in the tank, and it seemed to help a bit...

I really hope 2. and 3. aren't the case as it just got its service...

I pulled a plug and confirmed she's got a spark. Still won't start.

[ludenukka]

jump timing?

[Rob H]

I'm starting to think that may have happened. It's at the dealership now... Fingers crossed it doesn't need anything shipped from Italy...

And the verdict is in: New fuel filter installed during service has cracked/split. New new filter in place, and all is well.
