became interested in joining the group intending to do this trip since
the very beginning. By the same token I was conscious that I would have
a challenge to face: to make my Sundown STX Motard 200cc perform
accordingly to big machines such as: Mauro's Suzuki Savage 650cc,
Honda Magna V4 750cci, Lázaro's Suzuki Intruder 1.400cc and
Kawasaki Vulcan 1.500cc.

went very well, and the
average speed we maintained was compatible with that I normally keep
during my solo trips (normally ranging within the 80 - 115 km/h bracket).

my return to Goiânia - GO where all we are based, I had my
serviced (engine oil change and chaindrive replaced, as I perceived
that the chaindrive was nearly splitting). I put a chaindrive
better quality this time, I kept the front and rear sprocket as they
were still in very good condition.
I had to have my bike's speedometer redone, as the internal mechanism
was completely destroyed due to a malfunction. I could have
disconnected the cable in order to preserve the internal mechanism
intact, but instead I kept the same working and all the parts were
It is worth mentioning that my bike's performance - with the 14 teeth
front sprocket - improved substantially, provided I use the fourth and
fifth gears accordingly. Let me explain better this situation: if
I intend to remain at the 110 -115 km/h bracket I will have to revv the
engine towards the 8.000 rpm in fourth gear (1.000 rpm before entering
the tachometer red zone that begins at 9.000 rpm) and putting the fifth
gear to work. However, if there is frontal winds or even an
uphill stretch of road I will have to return to fourth gear and try to
hold the engine around 8.000 rpm.
In exceptional conditions (without frontal winds and in an levelled
stretch of road) it is possible to take the most from the engine using
fifth gear and travelling with the engine revving at the 7.000 - 8.000
rpm bracket, thus keeping a speed around the 115 km/h mark. This
situation (the need of using constantly the fourth gear) is caused by a
simple fact that is of fundamental importance: the Sundown STX Motard
engine has a small output (around 16.2 hp).
In spite of that I have been travelling with it because I like to face
challenges with small motorcycles, simply for the sake of it.
returning to Goiânia - GO I did a basic maintenance and cleaning
job in my bike. I perceived that the battery wasn't charged
enough to start the engine, and then I decided to charge it through a
low-current charging. I did it twice and didn't have the expected
output, so I decided to buy another battery for my motorcycle.
This time I bought an Heliar battery instead of buying again a Yuasa, like that I bought in the 7th of February, 2009. The battery I bought has the AGM (Absorbed Glass Mat) technology. It cost me R$ 130,00 and its specification is HTZ7L.
general performance of my bike, principally concerning the electrical
system, didn´t improve at all after the battery change.
Thus I had to adopt new measures: I changed the rectifier and I
sent the stator for a general refurbishment of the coils. The
general cost of both services totalled R$ 287,00. Now I
perceive that the general functioning of my Sundown STX
Motard is back to normal.
The electric starter puts the engine to run at the first try, even when
it is cold (first start of the day). And my bike's electrics
general functioning improved substantially.
Tracing a basic comparison between bikes of Japanese origin with those
of Chinese origin we can make a clear affirmation that the former have
stronger and better built electrical systems than the latter.
On the 22nd of August, 2011 I perceived that the speedometer
began to play up and finally stopped. I returned to the workshop
where I had it redone, and we found out that the internal cable was
broken. After trying to find a similar cable among dozens of
them, we figured out that the cable to fit the Honda Titan KS, 2009 was
similar in length and at the end finishings. In this way we
changed only the internal steel cable, and kept the original external
On the 15th
of September, 2011 by 22:30 hs when I was heading home returning from
the weekly meeting of motorcyclists at Paranaiba Avenue (in Goiania -
GO - downtown), my bike had a general electric failure. My friend
Mauro Gomes that was riding alongside with me in his Yamaha XTZ 250X
pointed out that the problem should be related to a main fuse burn out,
and I agree with that. But instead of trying to fix the bike by
the street kerb at night I decided to push it home, and so I did.
On the following day I thought about the rectifier recently changed,
and my guess was confirmed by the mechanic who did the service.
He suggested to me to put on a Honda CB 400 rectifier, due to its
sturdiness and trustability. As he had an used part in his
workshop we fixed it on my bike. And after replacing the burn out
fuse for a new one everything came to normal regarding my bike's
