Hello I own a junak 901 with a capacity of 50/70cmm from new purchased in 2011 to date Junak has traveled nearly 17 thousand km What I really like about the moped is the simplicity of the whole motorcycle, there is nothing complicated in the repair process, simple design, availability of parts is huge and easy to obtain. This is the second repair of the engine since new due to the fact that I ride a lot, parts wear out, now I have overhauled the engine again and the motor fires up from a shot, the larger gear ratio gears allowed to run longer in gear and achieve better results speed in km ends as soon as the pointer passes 80 I like to test various products with them especially carburetors and filters to get better results in combustion and on power of course it is possible but several carburetors of different manufacturers of fuel nozzles you need to have to get such an effect . Parts from gmoto I buy because it is a proven seller of parts and really parts are of very good quality than on other sites only now what I bought starter chain sliders significantly differ from the original I would say more that the quality and material are other weaker but for everything there is a way site I recommend to all lovers of unicycles

I installed in a 2010 Barton Fighter moped. After mounting the moped clearly came alive, it became very sprightly, the top speed also increased. After starting from first gear it can sweep the wheel, and after releasing the clutch faster it stands on the wheel, also when shifting to second gear the front end likes to lift gently. Overall, for this price I can confidently recommend this cylinder to everyone. I recommend 100%

Zipp Neken 2 50cm3 2019 Installation of the carburetor very easy. Just screw two screws from the carburetor mount, put the throttle on the cable, screw the throttle. Install the air filter. Put on the fuel hose. Put on the manual suction line. I rate the installation of the carburetor as very easy even with no knowledge of mechanics. The carburetor after installation is pre-adjusted ready to drive. Recommended.

Moped gb Street 50 , on the old original carburetor muddied up on cold engine. No power despite the adjustments made. Today after installing a new carburetor moped revived, a noticeable improvement in engine performance that I had not decided earlier to make this purchase only agonized and combined like the proverbial horse uphill . I recommend this carburetor. It is really worth it.

I have a Junak 901,I bought this kit because the motorcycle was already quite weak. I did the assembly for the first time, and it took me some time. So far I'm lapping , and I have no problem. I think Moretti products , are good parts and recommend.

The 50 cm³ cylinder for the 139FMB 4-stroke engine is an excellent choice for anyone looking for a reliable and durable replacement or upgrade for their engine. The workmanship is precise and the fit is perfect - installation went smoothly. After installation, the engine runs perfectly again, with smooth running and good performance. The cooling fins ensure efficient heat dissipation, which increases durability. A particularly positive feature is the high-quality material, which promises a long service life. All in all, a top product with a great price-performance ratio! A clear purchase recommendation for anyone who wants to get their 139FMB engine back in top form. ⭐⭐⭐⭐⭐

Moped - Barton Fighter Eco 2020 The store's merchandise filter specified as if this pad would fit my machine. It does not fit!!! The main hole is 3.5 mm too small, and worse, the spacing of the screws is also strongly too small. I had an emergency situation and sanded the holes to my needs provisionally. But I am disappointed. For 139FMB engines, GMoto does not carry ebonite washers, despite the fact that these are the most common moped engines in Poland. And I see in the previous comments that this is nothing new.

Product arrived quickly and in full with fast processing and no complications. The price is fair and also very good value for the good quality. Shipping costs are also not as high as with other suppliers. As stated, the parts fit perfectly for my Romet Router WS 50 with four-stroke. I have installed everything new and everything is running great, just as I had hoped. I always order spare parts for my moped here and have never been disappointed.

GB Motors Street 72ccm The product fit my head perfectly, you can say that it was so good that it fitted by itself :D Namely, it does not leak, everything plays as it should, after firing the motorcycle the old power returned and the pressure did not escape through the valves. I recommend the product as much as possible as well as the store, of course. He buys here all the parts he needs, because all are always here :)

I own a cross with a 152fmh Loncin 110 engine I needed to protect the sprocket this protection fits perfectly it is well made, the holes are the right distance and the right diameter. The milling inside is well fitted so there is no play. The protection is thick which stiffens the mount. I recommend because the product is of good quality.

So far ok. It's working. I'm not complaining. Because how can you complain about a module for 10 zl???. And seriously, I felt a noticeable difference in the power of my machine :-). Unfortunately, I do not have a working tachometer, but I have so about 10 km. more speed achieved and much quieter motorcycle :-) Greetings to the nice sellers :-)

Very good build quality. The head with larger valves to this plus the replacement of the main nozzle in the carburetor gives incredible power. And if you replace the gearbox with more teeth in the engine it flies like a storm. 2 times faster and much more powerful. I sincerely recommend. I have taken a lot from this store and everything great.

I am very satisfied with the purchase of a carburetor with manual suction 139FMB 4T from gmoto.pl. The carburetor is of high quality and works very well. The engine runs smoother now and I save more fuel. I recommend this carburetor to everyone who is looking for a reliable and efficient part for their motorcycle.

What to write here a lot. I have a moped Romet C1 and it is always difficult to fit some parts to it. In the case of the handle, which I also ordered from this website, I succeeded, but not with the gasket. I do not see the point of sending it back, because it would be a terrible waste of bilge(

Ogar 900 '08 Compared to the gaskets once purchased from another site, these seem to be much better in terms of the material itself as well as the fit. However, the gasket between the crankcases seems to have to be cut out everywhere to put the cylinder on later.

The cylinder fits perfectly to the engine 139FMB, the moped after such tuning laughs beyond recognition, I wanted to emphasize that I did not replace the gasser, it is the original from the fifty, only the nozzle replaced with a larger + head and everything runs perfectly.

There are hard and soft rollers, I personally prefer the soft one because the roller works in extreme conditions of temperature and oil hardens over time and can crack or there is a breakage of a part, therefore I choose the soft material

As the only product I have a negative opinion because the quality of the thread in the nuts purchased was tragic both in terms of its appearance and the internal diameter on which the thread was made . I did not install them on the motorcycle .
