    On this exhaust I want to take pipe for Malossi MHR Racing exhaust system, but will this work and does Malossi MHR Replica 70cc suitable for everyday use!?

    Hi Daniel,
    I have an almost new 2t AC zip and i want to improve on acceleration. I’m quite happy with the stock top speed but it just takes a little too long to get there. I’ve ordered an arrow chamber exhaust and am now thinking about a 70cc kit. I don’t really want to spend over 250usd. would i be better off just changing the transmission or going 70cc? Thanks heaps.

    I happened to have a pwk 24mm lying around so i also got the stage6 manifold for it. Any recommendations for what jet i should start jetting down from? 118?

    I installed the polini 70cc sport on my piaggio liberty and the top speed remains the same , all the other components are stock, i will recieve my exhaust+ clutch+roller weights+belt+ bigger airflow tomorrow.
    Im a little bit confused, why the top speed didnt changed? Is it because i have to put the racing exhaust+ clutch to see any difference?

  15. Okas

    My scoot is derestricted, i mounter the DOPPLER S3R sport exhaust , harder clutch spring engaging at around 5000rpm + a +30% contra spring, i added 10points bigger mainjet, +carbon reed valves. it has more sprint , btw the carb is a 12m dellorto

    Hey Pro-Daniel whatsup! =)

    I think this is a very common goal for urban scooters worldwide, and will help a lot of people!

    I just got this stock Aerox 50cc 2003, previous owner know nothing about whats done etc, except all parts are “stock”. It tops about 70kph so guess some stock stuff got de-restricted.

    Reliability is the sole reason why leaving my beloved veteran moped for modern scooter in the first place.

    I would like to accomplish these things for about €300-400 ($400-$550), in order of priority, nr 1 is first priority:
    1) A reliable everyday scooter – minimal breakdowns! Increased service intervals, while still practical interval, would be ok!
    2) Without dropping top speed below 70kph, I want as good acceleration as possible, power wheelie if possible.
    3) Id like it to go ~80kph (maybe even 90, but beyond that would be wasted power rather put in acceleration and/or in beer)

    What stuff do you recommend for a budget of about €300-400? What service-intervals do you recommend for that stuff? Budget is not fixed, if you really suggest putting in another 100 for a lot better package ie bang/buck, then I will surely consider it.

    Randy at |

    Dear Daniel,

    I already bought the stage 6 sport pro mk2, dellorto 17.5mm carbo and the polini hi speed evo R02 variator.

    which clutch springs, clutch, and torque drive is the best for the setup?
    is the polini exhaust good for the setup?if it not I will buy the yasuni c16/r
    what is the top speed with this setup?


    1. James
      James at |

      The yasuni c16 city derestricted is a great road legal exhaust produces a lot of torque

      James at |

      You really only need one gear up kit unless you using high end track part like stage 6 rt 70cc or 95cc otherwise your bike won’t pull both gears secondary gear up is the easiest to fit

    Hey I am currently building a aerox using stage 6 racing mk2 cylinder and stage 6 85mm crank with 12mm gudgeon pin roughly how many miles will I get out of these parts using my bike on a daily basis

    Hey Daniel, i have a 2015 roughhouse 50. I’ve had a mechanic install a Stage6 MK2 70cc Cyl kit, 6g rollers, and a mallosi yellow contra spring. I also have a Stage6 Pro Replica Exhaust and racing paper air filter. It performs less quality than stock (even with jetting). I’m sure i’m under carb’d. I’ve purchased a Stage6 R/T Type PWK21 Carb but the stock intake is too small. Shall i get a performance intake (NCY) or back the carb down to a 17.5mm Dellarto? Thanks much.

    Hi Daniel !
    So i got a malossi 80cc kit, malossi 7g rollers and a giannelli extra v2 exhaust
    there’s more tuning to come. And i was wondering is a giannelli extra v2 exhaust any good for a malossi kit 80cc kit ? Oh and is the malossi 80cc kit better than the polini kit ?

    Hi Daniel..
    I saw on scooter-attack that the Stage 6 sport pro mkII can gives 15-17hp right out of the box now. Which setup can i use to give me that result?
    Reaction please….

  29. Drandon
    Drandon at |

    Daniel, so we got her all together.. Stage6 Sport Pro MK2 Cyl, Stage6 21mm PKW Carb (102 main jet), Stage 6 Pro Replica Exhaust, NCY Intake, Stock Variator with 5.5g Rollers, and a yellow Mallosi Contra Spring. Acceleration is better than stock (though would like more), and she wants to go fast (50 at 3/4 throttle). Still breaking it in. When i let off throttle from 3/4 i don’t hear that “rang-a-dang” familiar 2t sound i did at stock. Normal? Also, manual says use 98 octane or higher, really? And, i should put more oil in gas tank in addition to oil tank with pump. Thoughts? I really appreciate your time and ideas. Thanks Daniel.

    Hey Daniel,

    Been trolling here for a while, I love your passion man, you’re a machine.
    I’m reasonably new to scoot tuning myself but I’m been on the spanners over a lot of other vehicles.
    I’m looking to build a drag scoot capable of 8.* sec 1/8 miles to run in a local meet. We have no scooter workshops out here or scooter racing for that matter. It’s hard to find any solid info online but I’m summising I’ll need around the 20hp mark with a well tuned transmission. Unfortunately for you I have several stupid questions. I currently have an aerox 50cc.
    I’m trying my hand porting some stock 50cc cylinders. Would you recommend a responsive cylinder to mild porting such as raising and widening exhaust ports, cleaning up transfers, port matching and adding material to the crankcase to match the previous volume? I was thinking a DR performance or Top Performance Due Plus for my goals? I am obviously measuring port timings carefully to make sure I don;t go too far.
    I’m thinking I will need around 15,000rpm to comfortably achieve my goal on a 70cc and if so will need a crank. Obviously there are many options, but I was looking at a Jasil Evolution for a cost effective solution.
    28mm carb, probably a OKO 28mm. Would a subframe kit to mount the carb over the rear tyre contribute noticeably to horsepower?
    Will I need an overrange kit to achieve my goal? On face value I think I can get away with secondary and/or primafry gears only.

    I know there’s some stupid questions which are probably common knowledge in Europe but I can’t read Portrugese/German/etc and google translate is hit and miss.

    Basically I’m asking, what would Jesus do?

    1. Travis
      Travis at |

      Or maybe something like a Stage 6 R/T 70cc with the porting mods?
      I just need a starting point, to know that my build will achieve what I want.

    Hi Daniel,

    I have a stock 2007 piaggio typhoon 50ac. It only goes as far as 70kph and I would like to take it to 120kph or more. Acceleration isn´t what I´m looking for… because I make long trips (30kms X 2 per day to go to work) I want to go faster and maintain speed (now when I go up hill my scooter lowers to 45kph…). Of course I also want something that will last, sometinhg durable and reliable.
    What parts should I get to reach this kind of performance with my tph 50cc 2 stroke piaggio?

    Thank You
