  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:

Parts Manufacturer Specifications What we 're using?
Tire Pressure Air - FR 1.75kg / RR 1.75kg Nitrogen - FR 1.75kg / RR 1.75kg
Spark Plug: NGK CR8EH-9 DENSO U24ES-N
Gasoline: 87 91 or 94 High Octane
Engine Oil: 10W-40 5W-50 Mobil-1 Full Synthetic Oil
Gear Oil: 80W-90 75W-90 Castrol Full Synthetic Oil
Coolant: HONDA Type-1 (50%-50%) HONDA Type-2 (No mix required.)
  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...
