Ok, almost ordered a 2015 Viper, but was a bit reluctant due to the fact it was an "A" model. I've owned a turbo Nytro and absolutely loved the fourstoke but wasn't a huge fan of the chassis. Am thinking about a 2016 Viper, but from the reviews so far, Yamaha needs a few minor improvements. 1) Better ski's 2) Better running boards 3) Roll over valve. All of you that own one, please chim in. Would be interested to know how you owners feel. Again, I have ZERO seat time, but miss the fourstoke torque. Maybe a new engine in the 2016? Interested in knowing what you think.
