2014 Won't Start BOOO....

[sr1355]

Alright a bit of background, bike was bought new April 25, 2014 and has just a little over 20K miles on it. All service has been done as far as oil changes, filters, air filter etc. Have LOVED the bike so far, alway run prem gas and haven't had a lick of problems until now.

Parked bike last week everything was just peachy, jumped on it Sunday and it turned over and tried to fire but didn't catch. Tried several more times but with no luck, I could hear the fuel pump charge on ignition and well as smell gas after cranking for a bit. Checked fuses and all seemed good. Figured another OEM battery issue as I've had this problem on other Yamaha so swapped out for new Classic MOTO. Fingers crossed pushed starter and it just turned over with no hint of trying to fire. Maybe it's flooded so tried WOT with no luck, I know may or may not work of FI bike. Now I thinking maybe new plugs so tear it down and swap in new OEM plugs. Put it all back together hoping and praying, this is my daily rider, that it will fire..... NO DICE!!!!

So I'm at a loss now, did some internet searches without a lot of luck. It will be off to the dealer unless someone has a thought on what I may be overlooking. ::010::

How long did you go WOT? It has been reported that it may require more than a minute of cranking (the whole time at WOT) to clear the flooded condition in a badly flooded bike. I'd get the battery completely and fully-charged and have at it. If it still won't start, then charge the battery again, pull the FI fuse, and crank for a couple minutes at WOT. Then put the fuse in and start normally.

Pulling plugs, letting the motor air out overnight, and replacing the plugs would probably work too, but WOT or pulling the fuse are easier options.

Thanks Mark, I'll give that a go, I found the threads on flooded no starts but I like the idea of pulling the FI fuse. Appreciate your input....

Another satisfied customer!!!! That was CRAZY I would never have thought I would need to crank it for over 2 minutes but it is running and doing a full warm up as I type. I did not pull the FI fuse.

Glad you got her going.
Crankin on it for that long just don't compute with me. I understand what's happening, but............damn that's brutal.
You should ride her to the Dairy Queen and treat your starter motor to a large ice cream cone. ::013::

Glad you got her going.

Many moons ago, I think someone checked what happens at WOT and the throttle butterflies only open 25% or so. So while WOT apparently engages a fuel cutoff to correct the flooded condition, the engine is only getting a little bit of air and that is why it takes so long. The more flooded it is, the longer it takes.

I doubt there is any need to crank in one continuous session, so if you're worried about starter motor overheating, doing it in a few 30-sec sessions with a minute or two of cooling between should be fine. Just make sure you anytime the starter button is down that the throttle is hard against the stop.

I wish Yamaha would address this, but it bites infrequently enough that they've just decided to ignore the problem. It has been theorized that the issue was corrected in the 2014-2015's but your experiences tends to refute this.

30 seconds is still a long time to me, and I'd never hold a starter button for anywhere close to a minute or more. That's crazy.
There's got to be another way.

Now I see a post from today where a guy was hammering on his starter and the bike caught fire. ???

Fine, only grind for a few secs at a time if you want. If it takes 60-secs of starting to clear the flooding condition, it doesn't matter how you do it - 1 x 60 sec or 10 x 6 sec. Slice and dice it any way you feel comfortable with.

May want to read this before you WOT the hell out of your starter.
May be a rare incident indeed.
