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!!
Don't worry about it..

The head is not perfectly level, I can feel the piston getting caught up when I tighten it down completely.. might wear in but I’m having multiple issues.Bad stuff:1) the head might need to be leveled2) the carburetor needs the stock jet changed out to a smaller jet, I swapped for a 65mm and it’s better but I’m gonna try a 60mm.The bike was getting way too much gas with the stock jet, like I was full throttle..3) the carb throttle connection is a weird one. You put it through the front and hang the knob out the hole and it fits in behind the slide into the carb. I shoulda took pictures to help people like myself.4) The throttle kinda sticks I feel like the spring is too soft..5) Bike wants to go without touching the throttle,6) bike will only idle with choke on, its kinda hesitant, then gets spurts of power, then wants to die if I let off the gas when riding. maybe due to uneven head and piston sticking…Good thing is, definitely more power!Phone said 26 but I didn’t max it out cause of the new build. Wanna figure out the tune and break it in before trying to hit max speed.I shoulda just got the red version due to the fact that it matches the rest of the aftermarket parts that are available on Amazon, not many gold accessories or deals on what there is.Might just return it if it gives me problems for more than a week.. it’s the same size 44mm piston as the stock piston, both are 44mm, only difference is 2 little windows bored out of the side of the new one. Could easily be dremaled out of the stock piston.I’d recommend just a 47mm head and piston kit, and doing some research on tuning and improving your stock carburetor or the NP carbs, they are much more tuneable than these HP carbs, I think you could get the same effects if you figure it out, I might have to go back and follow my own advice here.Waist of money for my case, so far anyway I’m not happy with the kit.

So I’ve had a lot of issues already. I originally got this kit and one of the piston rings were broken in half so I had to return it to get another kit. I’ve just recently got the new kid and I’ve realized it doesn’t fit my crankshaft. Luckily go fit has a crankshaft that supposedly works for you, I hope you are hands-on with turning wrenches because this is going to be a project in all pretty good for the price. The carburetor is excellent and it seems to be pretty high-quality for the price.

I put this kit on a 50cc 2 stroke motor I bought off Amazon and you can tell a big difference. Only suggestion is to make sure not to over tighten the carb intake flange bolt it will snap. Youtube how to install the kit. Really simple once you dive into it

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

Vraiment surpris pour le prix, le kit et complet et de bonne facture. Très résistant il m’a servie pour de l’amusement très bonne enfants pour des adultes allant jusqu’à 80kg sur une pocket 😅 ce qui m’a surpris c’est que le kit a tenu sans rodage comparé à l’origine qui était bien roder…De plus le kit augmente pas mal la vitesse de pointe et le couple ce qui et plaisant.

I would pass on this kit. I received mine with a inch long crack in the base of the cylinder, piston was jammed up in the cylinder so tight the whole thing is either defective or damaged. Copper head gasket was thrown in a bag with all the hardware, piston rings, wrist pin and bearing. Which deformed the copper gasket beyond use. Just plain old bad quality stuff and ignorance. I ordered a kit half the price (from a different manufacturer) and the difference is night and day. Stay away from this company. My full circle crank came rusty as well... Cause its apparently too difficult to oil things lightly before packaging. JUNK!
