Testrun - Sachs MadAss 50cc 4-stroke

[superfunnyman123]

where did u find the new gear ratio kit?????

[Casal70]

@superfunnyman123 Just buy a frontgear to a Honda MT5, Derbi Senda or chinese 4-stroke dirtbike.

[WILBObach360]

would this after being tunned be legal for a 16 yo on a provisional licence?

[krusi3]

I like what you did. i just bought one of these, heaps of fun. i want to upgrade it aswell with out changing the engine.

[Jordy684]

is this straight from when you bought it ? or did u tune it

[Casal70]

@Jordy684 Tuned

[Jordy684]

@Casal70 what did u use to make it fast cause im new to biking so i dont know which one of them made it go faster and = how much did it come to just for the added tune for it to go faster

[Casal70]

@Jordy684 In the movieinfo can you reed a complete list.

Nothing do so much, but everything do much together to improve the acceleration and topspeed.

But, the first thing you can is chance to a new chain-gear, the small on the engine. A gear from Honda MT5 is perfekt, a model with 13 teeth is right for small tuning. This make the bike 10 km/h faster.

Then you can make the weld in the exhaustpipe flat. This weld is in the begining of the pipe, near engine.

[Casal70]

@Casal70 Than can you get a sportairfilter and a bigger mainjet. you MUST chance mainjet! If not, the engine goes really bad and are going to broke. A size between 65 and 70 can be good, test what is best.

[yehyehdan]

is mph?

[360volume]

is that kph ot mph?

[Casal70]

Kph / Km/h

[skaternippel]

how much bpm do you have ?

[Casal70]

Bpm? ...rpm?

Topspeed @ 10 rpm

[StereoGringo]

mayby 10 000 rpm :D

[euseMC]

what did you do to its cylinderhead?

however nice madass!

[Casal70]

The channels in the cylinderhead has been optimized for best flow, not easy and you need to know what you are doing before you just put your grinder/"dremel" in the head.

[stalewiak]

Jakie  to ma blokady ??

[Casal70]

English plz.

[Casal70]

No automatics, only manuell.

[ikeasokk]

Slow as hell xD get some tuning dude

[rutkutusperatus]

I ran 74km/h to my original meter at downhill with rpm limiter de-attached and gearing 13/53, that was fun :D. 74km/h original meter= about 70-71km/h to GPS. Not other modifications made :D , I have normal airfilter, engine and everything else, this thing is killer sometimes!

[produKtNZ]

Speedo is in mp/h? or km/h ? looks like kp/h but i'm not sure :)

[Casal70]

km/h ;)

[produKtNZ]

Well then, I'd like to say Welldone because your max speed on a 50cc isn't all that far away from what my '08 Stock 125cc gets O_o

Here in NZ, a country of around 4 million (mostly Asian immigrants) we don't seem to have the expertise/ or the people willing.

Off-hand I can't think of a single place I can go to get my Cylinder head gasflowed & ports polished etc!

[twigg2050]

Nice!!

4 strokes, You cant beat em

[Marko7272]

yes you can. with a 2-stroke. regardless the tuning you've made, this looks fucking slow.

[odi22865]

To Bad for the video quality :(

[ABCD010495]

Sorry I am French and when I makes the translation of that you says to me his(her,its) work but not for everything the words

[ABCD010495]

What configue driving kept silent?

[Casal70]

How do you mean?

[ABCD010495]

How made you to go also with your madass because I pocède one and I go less faster than you thus I want to know how had made you to go faster.

[Casal70]

I replace some parts to get a new Setup:

* Hebo airfilter

* 68 mainjet (bigger)

* Matchported intake

* Tuned cylinderhead

* Polshed exhaustport

* Removed weld in the begining of the exhaustpipe

* Raceoil for better clutchperformance

* Gearing: 14/53 (bigger gear(?) on the engine)

[opuliski]

My aprilia sx 50cc goes 95-100 km/h

[Casal70]

Who cares?

[odi22865]

You don't,

I don't,

We don't

[HayLow3fan]

jag kommer ihåg det där ljudet! det låter exakt some en 4 takts 125as fyrhjuling jag kört en gång. jävla va svårt det var att växla, ajaj. men kjedjan hängde ju bara typ 5 cm över marken så.

[salamy2222]

sry but i have to say 2 stroke for the win.

[romaf06]

hi im seriously considering buying one of these bikes...but i heard they are very very slow at 50cc. Is this speed test a 50cc madass bike or is the motor tuned?

[Casal70]

Hi!

It is tuned, but still the same cylinder and head. It is not so easy to do this work.

In stock is the topspeed about 50-53km/h and the acceleration ok. (not more than ok).

[ohnotyouagain]

Snyggt;) men fan va man måste trimma dom där för att gå 70 typ XD derbi senda så drevar man som får man dom att gå 70 eller lägg på ett trimrör så kan dom toppa 90-95 men då ska man ha rätt drevning också:P

[radiopleppofan]

Drar den på bakhjulet ännu?

[Casal70]

Du får gärna definera.

[balleochdick]

hur fort går den orginal?? =)

[Casal70]

50-53

[balleochdick]

okej ^^

[TickTackToe20]

nice

[MrsPoker]

I dont understand shit of the setup (english..) but it does look good, so could you give the setup in english? what did it cost you?

Nice place you live.. sweden?

[Casal70]

Yes it´s sweden!

Setup:

* Hebo airfilter 16€?

* 68 mainjet 5€

* Matchported intake 0€

* Tuned cylinderhead 0€

* Polshed exhaustport 0 €

* Removed weld in the begining of the exhaustpipe 0€

* Raceoil for better clutchperformance 17€

* Gearing: 14/53 5€

[joemreyes]

That is a sweet Tachometer, where did you get it? my madass is a 160cc 1250 charger from OORacing, and I'd like to get a tach like that on mine.

[kalimalotus]

helll yes

[Katalaneren]

hva slags drev har den? jeg tenker på hva slags type

[Casal70]

Drev till Honda MT5 passar fram.

[Smety15]

75 km/h great

[Casal70]

Finns ingen plugg, bara en svets i röret som ger hur lite som helst om man tar bort den

[Pelleman666]

ja e inte så bra på motorer(än) men tror du d räcker me att ja drar pluggen?...asså inte helt ja vill ba få upp den i typ 70..

[Casal70]

Tar du bort varvtalspärren och monterar ett 13 drev fram från mt5 så gör den det =)

[Nizzen9]

Hur fort går den original?, funtar på att köpa en men bara om den gör typ 55

[Casal70]

50 fast om man segar lite så gör den upp till hela 53:P

[DannyHamren]

Va maxar en orginal madass ?

[Casal70]

Sådär, men det fungerar okej iaf, men efter att man har vässat till dom lite så blir det lite bättre.

[Pelleman666]

hur bra acc ere i den? ja e nästan säker på att ja ska köpan(ja fyller femton efter sommarlovet, o ska baa fixa pengar) o den e jävla nice asså:)

[Grovsnusrules]

Klent.

[Casal70]

Japp.

[okmijnuhbygvtfc09876]

är den där trimmad?

[Blomm4n]

Antar att det var ditt "präktiga bygge" jag läste om på moppenet.. asbalt!! har en madass själv, men får verkligen inte trimma...

[Casal70]

Beror lite på hur du difinerar stark, men gött vrid finns det alltid i dom, bottendrag också på topp eftersom det är en 4-taktare. Dom är tändningstrypta till 50km/h orignal och om man försöker smita långsamt mot varvstoppet går det att få upp den i 53km/h.

Drevar man slänger man på ett 13T drev till MT5 och bara plockar loss en låda med den tunnaste sladden så är varvtalstrypningen helt borta och den toppar med drevet runt 55km/h med bahagligt varvtal som det inte är med originaldrevningen.

[Pverm]

Fyllde 15 i november och tog eu-kortet nu i veckan. funderar skarpt på att skaffa mig en madass, verkar rigtigt go juh :P hur snabb e den faktiska max hastigheten otrimmad, och e den nå vidare stark?

[Casal70]

Absolut.

[Fellu1]

ja e 160 lång :P skulle den passa mig? :D

[Casal70]

Man sitter rätt böjt fram redan om man är normalt lång, men med ett lite högre styre blir det bättre, helt klart, men du kan ju inte sitta helt rakt. Jag är något centimerter från 190 och jag tycker det funkar bra, provkör någon!

[Lieutenantsexmachine]

hur stor är en madass? jag är 190 cm lång och funderar på att köpa en för att åka korta turer i byhålan här i norrland. Men kommer jag behöva sitta som en räka på den med ryggen krökt som en sågbock???

[callebo]

årsmodell? :p

[Casal70]

Summer of sweden. :D

[lenselinkJ]

What country are you from? I like, the landscape pretty drive-able for a madass. I'm hoping to get my one in two weeks!

[Casal70]

Much more, take away the rpm limter, sport airfilter, main jet(68), ported cylinderhead, ported intake, ported weld "in the start of the exhaust" and the gearing is 14/53.

Sorry for bad english...

[esquivelia]

Have you done any modifications besides the rpm gauge? If so, what? Yours goes about 12 mph faster than mine. (33mph/53kmh)on level ground.

[Lukas005]

have yuo tuned it??

[Casal70]

It´s my phone, it´s vibratesound.

[TehPwner777]

yo whats with the fuck sound by low rpm?

[svat11]

Tja. vilken internet affär köper du dina varor på? :P

[Casal70]

km/h

[JJG85]

kmh or mph?

[dildi12]

its ugly

[Gortax112]

Nice (:

[Casal70]

Sleepovernightmare: No, it is corectly connected to the pickupcable behind the engine.

[bozzen91]

Jag har inte lagt ner så mkt tid på min, köpte nytt cylinderhuvud med större kanaler och trimkamaxel på batterilagret för 500 kr. Sen kom sportluftfilter å 65 munstycke. Därefter fick jag ett 14 taggars framdrev å vipps går den 78!! Mer kommer snart!

[sleepovernightmare]

the rpm meter works inductive, you only have to wiggle it round the ignition wire.

[rutkutusperatus]

Was it hard to make that rpm meter work proparly?

[Casal70]

Maxtuned 50cc, thats the deal.

[Ma77Rostant]

Is that really still 50cc i got a 90cc in mine and it does those speeds but the 50cc wouldent.....how did u do that?

[Casal70]

tachometer?

[PiercePlowman]

is the tachometer factory?

[Casal70]

säkert laggt ner över 20h för att den ska gå bra.

Trim står till höger.

[Hejadolf]

Är den trimmad ? är det svårt att trimma dem? ller släppa strypningen

[Nazoe]

coool som fan :D
