I think I'm gonna agree with the skepticism on the rearset issue. Ya...it shouldn't break. But obviously it wasn't under normal riding if the guy broke his foot. How many riders here have that much weight on their feet that they couldn't immediately pick their foot up if the rearset fell away?

Sounds to me like Yamaha has some pretty severe quality control issues.

I'm dealing with the fuel injection cutoff on my 2006 FZ1 that sounds similar to the hesitation mentioned. In addition, I experience the same engine stall at low speeds.

I've been looking through other newsgroups about this problem on the FZ1 specifically and the unanimous solution is to purchase a Fuel Cut-off Eliminator (FCE) from Ivan's Performance Products http://www.ivansperformanceproducts.com/. A Power Commander alone will not suffice.

Since the FZ1 and R1's engines are supposedly de-tuned versions of one another, it would not surprise me if the same fix worked for both bikes.

With regard to the rear set issue, I have no direct experience and cannot comment.

Now, with this said, it still seems to be an example of how not to release a product. Let's face it, these are obvious flaws and should have been caught by QA. Apparently, Yamaha is either reticent to mention them or is under such pressure to get the new product to market that they judge the flaw to be "acceptable". I find this troubling.

I highly doubt that this "ISSUE" with the 07 R1 engine has anything to do with your FZ1s "hesitation". Plain and simply reasoning here brotha, IT'S NOT THE SAME ENGINE. Last years R1 is your closest comparison, and I don't know ONE person with an 04-06 R1 that will complain about thier bikes engine performance. But the 06 FZ1 and 07 R1s? Difference here? Huge. Start with the 16/20 valve switch over.

Let's assume that the engines are different. You're correct in that there are many mechanical changes to the engine structure itself (i.e. 4 valves/cyl vs 5). However, based on the description of the problem, it sounds like the fault is in the logic used in the fuel injection system (i.e. software/firmware). Add to this that the FCE fixes the FZ1 problem by changing this logic, not changing anything physical in the engine, it again points to faulty fuel injection logic.

I don't know if both bikes share an identical fuel injection system (software & injector) but it stands to reason that a lot of it would be common. Since problems in both bikes sound similar, wouldn't it make sense that if they fix the logic in one it would fix it in the other?

Most likely the Throttle Position Sensor. There is a recall for that, free replacement thru Yamaha dealerships.

I'll stake a PBR on it that Yamaha won't win the AMA Supersport title this year.

That's was I was going to say... Yamaha has been fighting this TPS problem since late 04. Sounds like the same type of deal with the 07's.. I already had mine replaced.. It was worse on the 04's thru 06's. It would actually stall out in corners and other places that weren't very nice. I never had any problem with mine. Had it replaced anyway.

The 5500rpm lag?? WTF, sounds pretty petty to me...

The rearsets? Huh, quit jumping up and down on the damned things and they won't break...

Why so many problems with the 2007 Yamaha R1?

Because it's not a Honda R1.

i wont buy a yamaha, but the rearset issue would be something that would make me steer clear. Tons of bikes on the market that go through the same abuse yet don't break. If i wanna jump all over my rearsets i damn well should be able to without fear of them breaking.

2. I am sure that the rearsets are not breaking under normal riding conditions, if your doign wheelies etc then what do you expect there is a lot of force on them. Fix is to don't do wheelies or get some AF rearsets!!

3. Learn how to ride is the fix there, and even if it does stall, drop the clutch and it will fire right back up, retards if you ask me!!!

These are all really stupid ideotic issues!!
If your shelling out the dough for a new bike you should'nt have to compromise by changing your riding style because the bike you purchased is a steaming pile of shit that has serious flaws that should have never made it to market.

That being said they talk about this issue quite a bit in the latest issue of super streetbike, their fix was going down 2 in the back heh, but it seems to be an issue with the fly by wire throttle....

Even the 05 r1 lags at 5500 rpms if you try to just snap that throttle back. simple answer is ,ride in the meat of the powerband. the R1 dont have any bottem end power anyways,thats why i like to ride with the rpms up = no lag

To all the Yamaha faithful, I know you don't want to believe there could be a flaw in the bikes, but pull your heads out.

Saying "just don't ever ride a 5500RPM" is crazy, the bike DOES have the ability to pull from there, but it's brain is having an issue knowing it.
