Re: Very hard starting today

Has anyone with the non-start issue tried consistently holding WOT? Not half-throttle, not pumping the throttle, not occasional WOT. I'm talking twisting the throttle to the stop and holding the starter button down for a full ten or twenty seconds if necessary until it fires, clears, and revs.

If nobody has tried this, it might be the solution to an occasional problem. Not something you should have to do, but something that will work to get you out of the jam.

I have wondered the same thing. This usually works for me on a flooded engine.

Yes - when mine failed to start (after not running for 2 weeks but also not flooded), I charged the battery again and since "normal" procedures did absolutely nothing, I held the throttle wide open to see what it would do. It didn't start, but it did catch a few times, which is more that it had done before.

On the next run, (after charging the battery again) I got nothing, trying a few different things. On the 3rd recharge - it started just like normal, no throttle. WTF.

Re: Very hard starting today

Trevor have you heard back from Yamaha about your bike?

As a side note, my V-Strom would do the exact same thing about once or twice a year. If I cracked the throttle it would finally start with a big puff of white smoke and then run like new again.

I'd like to know what happened to black smoke?

Blue used to be oil and black used to be petrol, now we are blowing white?

Re: Very hard starting today

Isn't white smoke really water or antifreeze burning off?

Re: Very hard starting today

If it were antifreeze, you could tell by the smell, especially in a garage, where even with the door open you get lungs full of whatever it is. It was definitely not antifreeze. It had a distinct odor of gasoline, but I suppose there could have been a water component, especially with the temperature swings.

My money is still on flooding.

Re: Very hard starting today

I had the problem the other day after a couple of times switching the ignition to on without starting. I was actually telling my wife about the issue, saying that I shouldn't be doing that.

Well, the next afternoon, I got the bike out for a ride and had the bike wouldn't start after about two five second runs on the starter. I opened the throttle fully and it cranked. There was a heavy smell of fuel. That's the first time I've smelled gasoline since buying the bike.

I agree that it's likely a flooding issue, though I would have thought that the ECU would be intelligent enough to prevent an over fueling condition.

The programmers are supposed to be intelligent not the ECU. It's just following orders.

The code seems to be smart enough 99% of the time, but for some reason, the program can't handle the other 1%.

Or it's getting slightly wrong info in the first place. Hard to tell which without YAMAHA.

Graham, good point. But, knowing the effect of turning the key on without starting the bike and still doing it brings my intelligence into question :-[

Ethanol makes less smoke than gasoline. I think the flame is a slightly different color (slightly more reddish). I'm not sure how we got off on this tangent, but I don't think this starting problem or the reports of different colored smoke on startup after the problem has anything to do with E10.

Re: Very hard starting today

A few of us were at Romney Cycles on Saturday for the fuel pump o-ring recall - I'd emailed Larry, the manager, previously about these issues, and included the link to this thread. He'd forwarded through the appropriate channels, and the regional sales manager is visiting this week, and he'll following up with him.

Re: Very hard starting today

First time with hard starting issues here. Never had an issue before. Bike was not washed. Put away after a nice 4 hour ride.

I was in the process of installing headers, pipe, PCV, AT and when I had the stock muffler off, I decided to run the bike "just because I wished to hear with no muffler". Bike ran for 30 seconds or so. Shut it off. So the bike did NOT warm up completely. Completed the install of header, muffler, PCV, AT and go to start the bike. Bike just cranks, cranks, cranks but does not fire. Interesting. Called Dynojet and confirmed that if I disconnect their injector lines, but leave the rest of the PCV and AT installed, I am essentially returning the bike back to stock (just in case something is wrong the PCV). Dynojet confirmed my beliefs. So I disconnect the PCV injection leads, and just re-connect the stock injection leads back to the injections. Try to start the bike. Same thing. Cranks, but no fire. Can smell fuel.

Now if someone's theory of starting the bike and letting it run only for brief period of time (not to full warm up) causes the bike to go into "mid cycle" programming...my question is.....can we disconnect the battery for a specified period of time in order to "clear" the ECU and let it start "new"?


UPDATE: Got it started. Another three rounds of cranking with WOT and it got going. Warmed it up completely, shut it down, no problems again. Go figure.

Hmm, maybe yours is the special "Wankel" edition S10? Damn rotaries.

Hmmm. now that you mention it, it does remind me of my dear departed RX7. If I just started it for a short time in cold weather and then shut it off, it would be flooded the next time I tried to start it. But that was in 1987, you would think a 2012 motorcycle wouldn't have that problem. Mine did once, though.
