Anyone have a "dealer confirmed" explanation to "hard" starting?

[gbergma1]

Forgive me if this is redundant, but about every 4-6 weeks my bike is "crabby" and wont start immediately with a cold engine. There is no rhyme or reason to it, it isn't fuel type, battery, temperature, oil changes, sit time, etc. Take this morning for example, I just rode the bike 24 hours prior, started immediately, but this morning, I thought I was going to run the better all the way down. I gave it some throttle, but the engine just didn't seem like it was getting air, I gave it a little gas, and it eventually "woke up". Same story about a month ago. It doesn't happen with enough regularity for me to go to a dealer, but it is odd when it does happen. I day say 98% of the time it start within 5 seconds of pushing the starter (completely cold). I put about 300-600 miles per week on the bike, the battery is strong, and right now I am a little shy of 10K miles, and all service is up to date. Any ideas? No weird mods on the bike.... Any insight would be appreciated.

I have not experienced this problem but I have read most of the previous posts. When I start my Tenere I do not touch the throttle and have no problems. How about you?

The "other thread" on this problem has lots of theories. I haven't heard of anything official from Yamaha or a dealer.

::026:: I don't touch throttle and no troubles (knocking wood). Happy with the battery too so far and have not been using a tender.

I usually don't touch the throttle, but anytime the bike doesn't start immediately it seems to help in my situation. I am pretty certain if I take it in they won't be able to replicate it, but when I get the bike back home it will do it the next day.

Mine's got just over 7000 miles on it and it starts straight away on the button every time, even if I have switched it on and off again to check a bulb or look at the mileage on the previous day. I don't know if this helps much because I guess the UK bikes are different to the US ones

I have had this happen just once on my UK spec bike, after having run it for just a few seconds in the garage the day before. As already said, I don't hold out much chance of a dealer being able to replicate it.

Yep, I am in the just once category as well, and north of 18k miles on the bike. Bullett has about 8k on hers hasn't had the problem that I recall. When mine did it, I remembered some say to give it throttle. That worked. Normally I do start w/o throttle, however.

I know this post is a bit old, I'm just now seeing it for the first time.

I have the same problem, and have discovered, at least in my case, it is associated with a low fuel level in tank. The gage still reads fuel present, but "in the red". I've learned not to leave overnight, but to have at least quarter tank.

If this fuel issue/ hard start is addressed somewhere on forum, I haven't been able to find the thread yet. I know it's a very delayed response, but hope it helps.

Don't think you've looked very hard. You can't swing a dead cat on this forum without hitting another "hard start" thread. I doubt it has anything to do with fuel level.... I've had it happen with a completely full tank, a tank on reserve, and everything in between.

Just had 5th instance of the dreaded syndrome, this time after letting the bike sit for five weeks. No other contributing factors (e.g., key cycling, interrupted previous warmup, etc.). Fired once with closed throttle, then died and wouldn't restart normally. Took a LOT of cranking WOT to get it to go this time and it stumbled to life reluctantly. If I hadn't had the battery recently charged, I doubt it would have held up long enough to get it going.

There is no hard start , just rider error .

The evidence says otherwise, and there have been some unconfirmed reports of a bug in the ECU software that contributes to the hard start.
