i have a question i have also a o7 honda f12x turbo and the top speed i went was 50-55.. is their a problem with my ski if i cant go any faster then that?Is it a turbo? If so, I've been told by the dealer that there is a small valve that regulates the turbo pressure. If it gets clogged, it won't open and the turbo won't kick in. They say it's a fairly simple fix. Hope this helps.
PS--I have an '07 Honda F12x turbo
