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%

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.

very good quality cylinder head, adds power when the engine revs up, which can be felt on acceleration and top speed, gaining at least 10km/h if you add an A9 camshaft or more, you'll gain even more, that's for sure! Perfectly packaged .thank you Gmoto .

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 purchased valve seals for a 150cc quad. I also bought a starter and a set of gaskets also for this quad. With the quality of the parts I bought so far I am satisfied. As for the seller also no reservations. Fast shipping and hassle-free. I recommend.

the cylinder itself is great and the piston all the seals and piston rings . it's supposed to be a plug and go cylinder . NOT I have a jawu betka/kentoya twinshot and need to buy a new head because the original camshaft is not enough and need to adjust the valve .

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.

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 .
