Stage6 bigracing 77 am6 unboxing/ test ride 

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

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

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

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

The cases are original no porting was done

it was a dellorto 21 at that time

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

@@luka0090polini pwk is good its around €120

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

it's the piston which is 49mm

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

it says 49cc for legal resons

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

@@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

Yessss

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

Yes the cast iron cylinder will last longer for you

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.

I agree

You can use between 21 and 24mm carbs
