Dusty's 1997 Vmax
(now known as "The DustMax")
Powerful Toys - 2006
Lotus Exige and 1997 Yamaha Vmax
This whole saga began one sad day, riding my
beloved 1986 Kawasaki Vulcan 750 across the Howard Franklin Bridge that connects
Tampa and St. Petersburg Florida. Traveling about 70mph I heard a knocking
begin, shit! I looked down, saw oil on my left shoe and immediately pulled over.
Looks like I threw a rod and punched a hole in the crankcase. Stopped dead in a terrible
spot on a very long bridge, right in the middle of Tampa Bay...
After a tow and estimate from my favorite
motorcycle mechanics, I decided not to fix my best toy of 13yrs. The hunt
for a new toy was on! Visited many of the motorcycle shops. Online classifieds
seem to be the way to go, I can check all the local newspapers, Motorcycle
Trader, Excite and Yahoo...
Then it hit me... The Vmax!! I always liked
cruiser bikes and liked to ride them fast (110mph was no problem for two on the
Vulcan). Everyone always respected the Vmax, they are cool and fast,
One look at the Vmax engine should tell you to beware of this
The best deal in
the classifieds was on a stock 1997 Vmax with only 3800 miles! Sweeet... Easily
the best deal around on a Vmax.
A long drive was rewarded when the previous
owner opened the garage to reveal a beautiful Platinum Silver bike that was
perfect, yea! In speaking with him, I casually asked him how fast he had gotten
her up to... He replied that he didn't usually ride fast but did go over 100mph
once (and he was actually serious!) I had to laugh and quickly sign the papers!
Little did he know that in less than an hour MY new toy and I were cruising up
to 125mph (gotta love that acceleration!)
The "DustMax" is christened
Vmax enthusiasts know about the cool feature
called Vboost. Above 6000rpm or so a valve opens to allow the cylinders to
breathe from two carbs instead of one. Instantly you have arm stretching, scare
your passenger, wake the neighbors, embarrass the sportbikes, pass a Testarossa
on the left, break the law kind of acceleration. HTFO is the saying, Hold
The *#$% On!

"It's like driving a Dragster on the
street!" is my description of riding (rather piloting) the Vmax. The
bike has a 1200cc 4cyl engine with 4 carbs and a shaft drive that runs 0-60mph
in 3 seconds and the quarter mile in 10.5 seconds! The top speed is 150mph+ or
is realistically limited by your good sense... Many modifications are
available to make the bike much quicker due to restrictions by the EPA and
The stoplight to stoplight king... It is
great fun to hand out spankings to those that don't understand hp/weight ratios!

Time to melt the old one, Hooligan style!
Starting the DustMax
Doesn't everyone make a video of starting up their
bike? - lol
DustMax with Open Headers!
After the stock mufflers were pulled off, it was time for some loud wake
your neighbors fun before installing my Marving Slip-on exhaust.

A longer video with 0 to 100mph blasts... Not at
full throttle because I had a 19yo cutie holding my new video camera and
I didn't want to lose either one!

Vmax Goes Bye Bye
The End (Warning: Nudity)
Now that I have ridden over 500 miles and
bonded with my new buddy, it is time for some modifications... :-) The
VMOA tech list, various websites, and Vmax enthusiasts world wide have
documented great upgrades.
These are some minor things that I
have done so far:

|The first thing I did was change the oil
and gear oil (rear differential). I added some X-1R to both the engine oil
and about 1oz to the gear oil. Wow, what a difference! The gearbox is so
much smoother, neutral is easier to find, and the bike rolls easier in
neutral. I don't believe most of the additive hype, but this X-1R stuff is
used by NASA and endorsed by the American Motorcycle
|The bike had 3800 miles on it and the
original back tire needed replacing. A new Dunlop K591 grips great and can handle
the speed and torque that the Vmax is capable of.
Update: The Dunlop K591 has been discontinued in the size needed for the
Vmax. I just bought a Metzeler
170/80 big wide rear tire. Looks nice and beefy!
|To make the bike steer faster and improve
responsiveness, I lowered the front end 1.25" by sliding the fork
tubes up in the clamps. This in effect, de-rakes the front end a bit. The steering reacts much faster now!
|The exhaust sound was too mild. I drilled
out the rivets, drilled five 3/8" holes in each can, and re-riveted the
caps with some stainless steel spacers. Looks like stock, sounds great,
rumbles and allows more flow. Makes me grin every time I start the bike!
Note: This mod has been superceded by an aftermarket slip-on exhaust by
Marving, see below.
|Had to drill the brass plugs to access
the mixture screws and richen up the carb pilots to makeup for the
increased exhaust flow.
The Vboost servo has been disabled and
a switch added to open or close the Vboost valve. This allows the Vboost
to be closed during warm up or while in stop/go traffic.
|Pull off the tank cover and left
scoop, the round connector is the Vboost connection. Turn the key on and
off a few times and you simply pull the connector apart when the Vboost
servo is cycled open!
|The carbs needed to by synched as the
previous owner thought that one of the sync screws was the idle adj. I
bought a CarbTune II so I could sync the carbs myself.
This is a very nice tool, uses solid rods instead of Mercury. I used it to
sync the carbs and
now the DustMax hums! Check out this link for great
directions from Barry.
|Found a great deal on a windshield,
Florida does not have a helmet law now and 150mph bugs hurt the face! Cost
was only $50 from JC Whitney, the comfort increase is priceless...
The CyberMax headlight is very cool, the mean
"No Fear" eyes scare the cage drivers out of the fast
lane! I purchased it from Exactrep.

|I installed a Marving
exhaust, a fork brace and chromed frame braces from Exactrep in the UK. The turn out
exhaust is made in Italy. It has a great muscle bike look and sounds
super! The frame braces and fork braces make the bike much more rigid. It
now launches better and feels more solid in high speed turns.

Gives the bike more of a muscular look! I have always loved sidepipes...

120 Rear Wheel HP @ 8500rpm

|VTAC shift light and RPM limiter - look
straight ahead and shift at peak power! Anyone who has ridden a Vmax knows
the tach is in a dangerous place to look (down)!
This model has a feature that allows full throttle clutch-less shifts.
Preload the shifter by pulling up on it slightly, at a preset RPM the unit
momentarily disrupts the ignition, removing the load from the
transmission, and the bike shifts hard and fast!

The modifications have all been a great success.
The bike is tight and fast with no hi/lo speed wobbles :)
None for now... It is time to enjoy the bike!
I am waiting to see the newly designed replacement for the Vmax from Yamaha.
I found an abandoned warehouse - the
perfect setting for a hooligan. The exhaust and tire squeal echoing
indoors sounded awesome!
Gotta love those signature Vmax
