Stage6 bigracing 77 am6 unboxing/ test ride

here we unbox stage6 bigracing 77 cylinder kit for am6 and we compare it to a generic big bore cylindre

[@mrbeast8522]

The acceleration is crazy on 77 bigrracing i got an Derbi with that and its crazy powerful

[@Xaserix]

the difference is brutal!! im looking to buy a bike soon with this kit installed

[@motomaher]

Yes it's definitely awesome kit for the money just make sure it's on the richer side for longer life

[@bysoja8283]

radical rpm 🇪🇸🇪🇸

[@Zileee_Serb]

Did you put better ignition for this bike when stage 6 was installed or did you run with the original ignition?

[@stefanloven6873]

Did you change the Crankshaft? You need bigger carb! And i saw that you still had the original oil pump which is not recommended and you run lean!

[@motomaher]

What you said is indeed true but this was simply for testing purposes to compare back to back.
The full build video will be out eventually.
Hopefully you will be here again to give your feedback thank you

[@filipsimic4048]

nice video! did you just put new cylinder and pitson have you changed anything else

[@motomaher]

Yes the carburetor was a dellorto 21, giannelli exhaust and Malossi carbon reed petals

[@TERRORBARON1]

you should Change crankshift

[@AhvenRacing]

Did you modify the cranshaft house or did you just put on the cylinder on the motor?

[@motomaher]

The cases are original no porting was done

[@fullthrottleES]

is the big racing reliable or will it blow up within a few months? i use my bike daily and need a bigger cylinder, would street race 77 suit my bike better due to more use?

[@timminneboo2704]

Yessss

[@alexanderthomsen5211]

Yeah, these aluminium kits dont last that long, though i have heard of people drivkng 2500km with this one

[@motomaher]

Yes the cast iron cylinder will last longer for you

[@fco.ouzina9756]

El cilindro original de derbi senda es de aluminio y hay personas an hecho 20000km con cilindro original. Yo creo que stage 6 podría hacer 10.000km sin problema con un buen cuidado y mantenimiento.

[@motomaher]

I agree

[@quinwelmer271]

Witch carburetor?

[@luka0090]

I have same bike. What size of carb did you use in test ride ?

[@motomaher]

it was a dellorto 21 at that time

[@luka0090]

@@motomaher Price for that kit is 230€ right now. Does it worth it or should I look for other manufacturers ?

[@_eprioxs]

@@luka0090polini pwk is good its around €120

[@motomaher]

As long as you tune your carburetor right it should last for a while

[@LucyBlankFreestyleDance]

👍 Nice editing brah 👌

[@maxmusterman1592]

exhaust?

[@Moscoph]

i thought it was 77cc not 49 but diamiter is 49, I am a bit confused ?

[@GlobTheGlobul]

it's the piston which is 49mm

[@Moscoph]

@@GlobTheGlobul Yeah i figured that out to i didnt know you had to multiply half the diamiter by pi

[@swedish_meatball43]

it says 49cc for legal resons

[@Moscoph]

@@swedish_meatball43 diameter ≠ Volume (cc). You have to multiply the radius by pi then you get the volumen(cc)

[@swedish_meatball43]

@@Moscoph That has nothing to do with the text on the side of the cylinder. it says 49cc on all am6 cylinders Dosen't matter if its 70cc or 90cc. i was talking about the text on the side not the diameter

[@ServeraServera0]

You really called the top rose a generic knockoff
They are both their own thing, but I do prefer the aluminum stage6

[@motomaher]

This is a knockoff of the top performances kit it has no branding whatsoever on it. And it came in a generic brown cardboard box.
The genuine kit comes with single ring piston and this one had 2 ring piston

[@leopercic1770]

what carb should i use on this

[@motomaher]

You can use between 21 and 24mm carbs

[@syneqz7988]

49ccm xDDDDDDD i love it

[@swedish_meatball43]

[@temezion2131]

i have generic trigger x and i fuckking hate this bullshit chinese am6
