I'm sorry to say that for some unknown reason and after waiting a few days for all the
possible replies from the group, as far as it goes right now I'm the only Max owner
defending the V-boost as a clever and very well designed system to provide maximum
power out of the Max in all conditions (remember I'm talking about a standard Max, but
I'll go further into saying that even on a Stage one modified jetting).
I am totally convinced that most of the maxer's that decided to install a Dynojet S7K
noticed right from the beginning that their original super chunky mid range turned to
be a "let's see how quickly I get the engine over the 6.000 revs to feel the gutts of
my bike". I will once more repeat the theory and practice of how the system really
works (and I'm hoping that all the brave owners of a max make some deep thinking and
agree on some basics such as these):
I would like to clear one thing for you that I feel you have got wrong from the
V-boost arrangement. It was never designed to be nature friendly, clean emissions and
all that stuff, on the contrary it is a carefully designed system to benefit from both
low end torque and high end power. When your Max is running at low rpm's the higher
the velocity of the mixture is as it enters the combustion chamber, the better the
mixture is achieved thus a more powerful explosion is obtained from it; that is the
reason for the small size carbs and closed butterflies on the V-boost. As you approach
the 6000 revs, the engine begins to starve from lack of mixture coming from a single
carb and that is when.... the rest happens. This is a fact and it beats me why other
manufacturers never copied the system, but again, nobody brought out a bike to compete
against the Mighty Max (until now I mean) Now Honda with their 1100 X-Eleven, 145 Hp
and many others are fighting to grab the muscle bike kingdom.
If you read about people who have installed a different set of cabs (flatslides and
what have you), none will in their fair mind say that they achieve more power all
through the rev. range, just at the top is where a bigger carb will deliver better
figures than the V-boost and original carb set, at least on a standard engine such as
mine.
Just want to make sure no one in their natural mind has thought that the V-boost was
an expensive way for Yamaha to reduce the power of their bike. It might sound as a
joke, but for some it seems that was their whole intention and that is the furthest
you can get from the truth.
Bye for now,
