GOOFIT Blue 44-6 Big Bore Cylinder Piston kit with Carburetor Air Filter ignition coil Set Replacement for 43cc 47cc 49cc Pocket Bike Atv Quad Mini Motocross

Great kit. Fitted to my bike. Started up and ran perfectly. Just needed a new throttle cable as my standard cable wasn't compatible. But all in all very happy with the kit. Was easy to install. Would certainly buy from this seller again

Just refurbished the engine and installed this no issues at all, now to strip and paint the rest of the quad before I try it other than on the floor.

Kit is easy to fit and runs great the only thing is the coil is faulty fitted the old coil and runs fine

The bearing doesn't fit the crank which renders this product pointless without a different crank so it should be listed as needing a different crank or even sell the kit with the right crank

Great kit for tuning my kid's mini dirt bike! Seller is very helpful in any question! If you know your way around this type of engines, it will be very easy to assemble!

It’s a nice kit but i comes with a sparkplug that doesn’t fit in the head... I haven’t tried to instal it yet but the other parts look nice quality.

Brilliant and east to assemble powerful kit Carries a 13 stone guy around so well pleased

had no end of issues, from broken spark lead to piston hitting spark plug to head gasket not sealing or seating correctly to seal air tight. either ive a dud kit or there just straight up no good. 90

Ottimo kit per modifica

Es la misma cilindrada que el original con orificio de escape mas pequeño pero con la culata y culatín diferentes , estéticamente mas bonito y rendimiento parecido, Con una.Buena bujia ngk R y unos muelles de embrague mas duros (que no están en amazon), unas laminas de carbono es suficiente para un ajuste sencillo y duradero

What can I say. Very nice kit overall and you can feel the difference in performance over the stock engine. I had to add a base cylinder gasket though because the piston was hitting the cylinder head. I wish they would have provided a throttle cable for the carburetor because my stock one would not fit so be prepared. All in all, 100% satisfied!!

lo monte todo con facilidad y sin problema. arranca a la primera y es bastante potente.

Montato il kit come venduto. Ho aggiunto albero a spalle piene e pacco lamellare Polini..veramente soddisfatto...un consiglio che do..mettete del frena filetto sui tiranti del cilindro perché con le vibrazioni e la dilatazione termica si svitano...veramente soddisfatto.la mia mini e cambiata e si alza che e un piacere...CONSIGLIO A TUTTI .con pochi soldi si ha un buon risultato .
