I want 90km/hr...
04. Do you have 70cc cylinder kit for ZOOMER / RUCKUS?
I saw stores in U.S. carry it...
05. Do you have high angle camshaft for ZOOMER /
RUCKUS? I heard it helps on torque...
06. Why I have to spend so much money to gain so
little speed? I'm a cheap guy...
07. Why 06' ~ 08' RUCKUS run faster than older models?
My 03' only get 58km/hr top-speed on flat...

use? So many choices in gas station and parts' shop...
09. What else I can do to my RUCKUS? I want to
spend a lots of money...

01. Why my ZOOMER / RUCKUS so slow, can't even go uphill!?
Be realistic, your scooter is a "4-Stroke" and "50cc"...
It's nothing wrong with 4-Stroke engine, it's also ok with 50cc displacement,
but it's totally wrong for speed wise! Unless you swap engine or upgrade
it, there is no way you will have same torque as 2-Stroke 50cc scooters,
ask your friends who have 2-Stroke scooters such as HONDA
Dio or YAMAHA BWS II then try it, you'll
know what we are talking about.
We believe the main reason for you to bought RUCKUS is the "Look"
(We knew it looks tough and cool, blah, blah... OK!?), so beyond that
point, you have to live with it and accept how it runs! It's just
a "4-Stroke 50cc" scooter! |

02. How can I gain more power on torque / take-off?
Well, they should cursed you, because you blocked the whole traffic
line...
There are 3 ways you can gain more torque:
a). Upgrade it with bigger bore cylinder (Which is impossible! See
FAQ 04.), bigger carb, bigger everything... It
helps, ha!
b). Swap the whole engine to either a 4-Stroke 125cc, or 2-Stroke
100cc such as YAMAHA BWS 100.
c). Throw it away and get a 4-Stroke 125cc or 250cc scooter, since
you're a 4-Stroke lover... |

03. How fast I will get from your upgrade kit?
90km/hr!? Wake up, dude! Our STAGE 1 Power
Kit can increase some of torque, discharge the rpm limits which
controlled by ECM (Engine Control Module) within safety range, but
your engine is still "50cc"; After upgraded, you may have
10% torque increase without speed limit on top-end, maximum speed
may increase 5~8km/hr on flat ground depends on scooter's condition. |

04. Do you have 70cc cylinder kit for ZOOMER / RUCKUS?
We know some stores in USA have it; However, the big bore cylinder
kit for us means New-Molding, New-Made, New-Design on Cylinder Block
and Bigger-Valves, NOT came from a stock cylinder and bored it to
maximum size.
The stock cylinder is 39.5mm (49cc) and you can maximize it to 42.0mm
(63cc) or even bigger, actually most of stock 49cc cylinders can do
so, because they designed to take more than 4 times boring if you
seized engine, but cylinder wall will be thinner each time (0.5mm)
and somehow dangerous, please see zipped pictures. 
We asked manufacturers in Japan and Taiwan back in 2004, such as:
Takegawa, KITACO, DAYTONA, KH, CHAR-Mo... etc., their answers are:
"We can make it, but only few people would buy it, because price
for customer and total cost for us are too high."
As you may ware ZOOMER / RUCKUS engine design is totally different
with other scooters, so if you want to make a new cylinder block,
you've to make new crankcase as well, the molding expense and R&D
cost will be very high. We and our manufacturers concern the Safety
and Performance at the same time, that's why even ZOOMER / RUCKUS
original engine was released at 1999 in Japan, but none of us actually
making the bigger bore kits in past 7 years. |

05. Do you have high angle camshaft for ZOOMER / RUCKUS?
Yes, we do, it'll be available in Summer 2007, with camshaft and special
springs. |
 |
|
| |
06. Why I have to spend so much money to gain so little speed?
Because it's a "4-Stroke 50cc" scooter, it never runs fast...
Most people never had scooters before, so they have no comparison
to know the difference in between 4 and 2-Stroke, speed range are
totally different even they are all 50cc.
The ZOOMER / RUCKUS is not made for speed, 4-Stroke liquid-cooled
engine makes upgrading expense higher, one piece cylinder crankcase
design makes molding harder, that's why most of performance parts
are focus on Transmission, Intake
and Exhaust system; Also, majority upgrade
parts come from Japan have higher retail prices, that's why SCOOTER
by jiangwayne.com is manufacturing parts with associate factories
in Taiwan, then provide the customers lower parts' prices. |

07. Why 06' ~ 08' RUCKUS run faster than older models?
Don't worry, your 03' RUCKUS is normal... We believe HONDA changed
some electro-devices and parts in 06' USA / Canadian and after models,
see our ECM table for more details; Based on
our test ride, 06' RUCKUS can do top speed 62km/hr on flat ground
(From stock speedometer reading.) compare with 05' model's 58km/hr,
also faster when riding downhill.
However, it's still slow... The ZOOMER / RUCKUS in
Europe has "Dio Z4" engine, 4-Valves with Fuel-Injection.

08. What kind of gas, engine oil and coolant I could use?
There are hundreds of choices in gas station and parts' shop, but
not all of them will fit; Gas is very important for 4-Stroke engine,
we used to have 95 or 98 in Japan / Taiwan for better lubricate, so
higher Octane is better; Synthetic oil / lube always better than mineral
because it won't produce oil-mud and less longer; Also the coolant
should be same as Japanese car because the materials of radiator,
see following our recommendation:

09. What else I can do to my ZOOMER / RUCKUS?
Sounds great! If you knew ZOOMER / RUCKUS can't run faster, it's a
very good point to start; There are thousnad things for you to do,
depending on how fast you want to burn the money... Go play the decorating
parts and make your ZOOMER / RUCKUS shiny, see our upgraded models:
SCOOTER AF58 SANDY-Style, SCOOTER
AF58 TAKA-style, SCOOTER AF58 Type-J,
you will have some ideas. |

10. I'm in France (EU), my ZOOMER / RUCKUS is fuel injected,
do you carry parts for it?
Woow! Fuel Injection... We really want to test ride one if there is
a chance, except the engine parts: CDI, camshaft, carb, exhaust pipe...
etc., most of transmission parts will fit without problems: KITACO
Pulley Kit, POP Roller Kit (ø16mm),
KITACO KEVLAR Belt, Clutch
Pad Springs, KITACO Oil Shock, and
all other decorating parts will fit
as well.
Most Italian manufacturers have performance parts for ZOOMER / RUCKUS
since it's available in E.U.; Remamber, Italian parts always stand
alone and never blend well with Japanese and Taiwanese parts, because
only 4 major companies and they have to keep the parts unique; But
parts in Japan and Taiwan can always mix n' match with each other
because there are hundreds of brands and no one wants to be unique... |

DIY 01. HONDA Genuine ECM versions and stock roller weights table.
This table will help you on engine tuning and upgrades, 06' and after
models have different air filter box, 1 more breather hose from crankcase,
emission valve above the exhaust pipe. Also fixed the crankshaft bearing
problem on older models.
