Adding my own .02 I race Jet Ski's. 2007 Kawasaki produced the Ultra 250x. Several months after people took ownership of these crafts, they began to notice their oil level would increase by 3, 4, 500 CC's when they would change the oil. AND they would notice it smelled like gasoline.
People started to monitor this a lot more, with more and more coming forward saying they had it. Many said they did not as well. We had several people approach Kawi, and they never ONCE addressed/admitted the issue. So, guys started leaving the oil unchanged, and motors started blowing up due to the viscosity reduction. Maybe this got Kawi's attention, the 2008 model was "somewhat" better, but still had GAS IN OIL (GIO as we termed it). Then the 2009 models came out, and they also had signifigant less GIO.
They had a flow valve installed in order to keep the motor warmer so that the fuel FUMES (its in fume stage while motor is running, once it cools it condenses to liquid) would burn off. Now 2010 they have increased compression levels, and are hoping (this is my speculation hoping) the GIO is GONE forever. MANY owners had no where to go, but we were left changing oil every 10 hours! Guys dumped the Ski's so fast it was not funny! Others began to work on "fixes". Several aftermarket companies jumped on this. I purchased $500 in "fixes" for my ski. They seemed to work but many were pissed like many in this thread. In the end, nothing was done for current owners. No refunds, no returns, just warrenty work on blown motors!
We had hundreds of pages of threads on that forum, we had GOI Roll calls, etc, etc. But nothing got done with that info. Because I knew I was using my boat as a Race boat, I was fine with changing oil every 10 hours, as I usually changed prior to a race. BUT for the average Rec Rider, this would REALLY suck, and I would understand their frustration. Now many guys have retrofitted their 2007's with 2009/2010 parts. Granted part swapping on our PDP's might not be as easy. Anyways, I hope I don't sound like doom and gloom, I am VERY upset over this. I purchased my V10 on CNET's reviews, as well as the reviews here. I did a LOT of research, but now am having buyers remorse. I have not gone into RiBL (Rising Black Level) and I pray I don't, but if I doDAMMMIT WILL SUCK! I hope panny does something! As an owner that has not gotten RiBL, what should I do? What should we do?
I did purchase BB Black tie EW, so maybe that was a good buy after all if I need to use it. ManPeople downed the Sammy Buzzers, but not ALL had the buzz, and you could tell right away. Now, this is like a delayed time bomb! I think I would have rather purchased the Sammy, I would bet the blacks are better than some of the guys here that are having issues.
