The folks that have had problems, what were the temperatures when the symptoms were noticed? If it was cold or cool, were the symptoms noticed during slow speed, high temp lugging?

Any one with a known or suspected failure where the symptoms came on and didn't go away? It seems they are intermittent, mostly?

Don't know if that's true or not, but it's certainly a possible contributor. But if it is the ethanol, I'd say the "fuel pump problem" is an inadequate fuel pump for modern fuels. Ethanol is hardly new.

I got curious about the ethanol thing and did some searching. While I was mostly interested in my own area, I did find this US map of gas requirements:

http://www.mobil.com/USA-English/GFM...soline_Map.pdf

It's about a year and a half old, but still informative. I don't know what all the gasoline types are, but I think Oxygenated contains ethanol and I've got to believe the fuel in Cali has ethanol. Any correlation between this map and peoples failures?

My province of Ontario uses a 5% "average" ethanol content. The way that has been applied is that regular is E10 and premium doesn't contain ethanol. Mid grade is a blend of the other two, so E5. This fall new federal requirements will be for 5% as well, but I don't know if it will follow the Ontario model or just make everything E5. Haven't found that info. I also don't know how various states may vary content with fuel grades.

I haven't had a pump failure but did have one unexplained incident with the engine suddenly failing a couple of month ago. Thinking about it, there was one time a couple of months ago that I did have to buy half a tank of mid-grade (premium was out of service). Unfortunately it was too long ago for me to be sure if they coincided or not. I also haven't heard of a Canadian fuel pump failure, but I don't think there are that many Canuks posting. Also, if heat is a factor, it gets hot here, but not as much as the southern states.

Yep, Eline stuff is never cheap (I have a carbon Eline skid plate on my KTM)- thanks for the link.......have you noticed much yellowing of the carbon fiber from the heat? Good heat dissipation?

I've only had it on for about 300 miles, so I can't speak to the yellowing. The heat is only slightly better. Jet hot coating or ceramic is probably the best performer.

I like the eline cause it just looks like a gaping hole without it and shudder to think the day my leg gets trapped under that header. I burned many a pant on it, not to mention a camelbak strap.

Hot.

No low speed lugging here. I can be cruisin' on down the road and she'll start to bog down until it finally dies . . . you know . . . like you just ran out of gas. I mean really, that's what's going on, right? The fuel pump stops pumping, so it runs out of gas. Same feeling as when you hit reserve on a carbed bike . . . except I have no reserve to switch it to to keep it running. It just quits. Pull over to the side of the road, cuss at it, maybe smack it around a little just for good measure, then it'll start back up so I can get a little further. Repeat.

I'm pretty sure mine is beyond intermittent. I mean, yeah, it'll run . . . but not for very long.

So are there any reports of someone replacing the stock fuel pump with a new one and it happening again with the new pump?

I haven't heard of this happening yet so one would assume Yamaha engineering knows what the issue was and fixed it with the newer build pumps?!

I did have a shop confirm for me, through yamaha tech (US) that the fuel pump was never redesigned or revised in any way. I am willing to bet the difference is in the tolerances or assembly issues. Maybe they had 2 factories building them and one got it wrong and was subsequently shut down. I don't think there is anything inherently wrong with the pumps themselves.

New fuel pump came in today. Old one is still working but I'm going on a trip 14 hrs away from home so I decided I didn't want to risk screwing up the trip over a $200 part that people are obviously having numerous problems with.

The pump is bigger than I thought it would be and the box it came in is way too big to carry around on the bike. Anyone carrying a spare with them currently? If so what are you keeping it in and what are you packing around it to keep it protected? I'm open to ideas from anyone.

why not just put the new one in and keep the old one shelf.

Given how fragile the pump is carrying it on the bike will put it at risk from damage. I would just swap out the old with the new and be good to go.
