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!! ### ⭐ Carb must be tuned to your bike head isn’t flat. *by D***. on September 13, 2024* 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. ### ⭐⭐⭐⭐⭐ If you buy this 44 mm Big Bore Kit please make sure at your crankshaft will fit it *by J***5 on March 11, 2021* Very good product so much power and I'm 236 lb got me up to 40 -47 miles per hour ## Frequently Bought Together - GOOFIT 44mm Cylinder Carburetor Air Filter Ignition Coil Set Big Bore 53cc 54cc Top Kit of Piston for 47cc 49cc 2-Stroke Engine Pocket Bike Atv Quad Motocyle Red - Racing Heavy Duty Mini Moto Clutch Pad 43 47 49cc Engine Pocket Kid ATV - JRL Racing Heavy Duty Clutch Pad 43cc 47cc 49cc Pocket Dirt Bike Quad ATV Mini Motor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/62402701-goofit-44mm-cylinder-carburetor-air-filter-ignition-coil-set-big](https://www.desertcart.hr/products/62402701-goofit-44mm-cylinder-carburetor-air-filter-ignition-coil-set-big) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
