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

No possibility of replacing the timing chain for the 139FMB engine which turned out to be too long . Not recommended.

i have a 2007 kingway 50 chopper I bought new starter chain sliders because the old ones were already very worn and while driving I could hear knocking after installing the new sliders the problem disappeared sliders fit perfectly in their place and not as I bought in another store nothing fit here, however, everything fit perfectly I am very pleased with them and I recommend them to anyone who wants to buy them.

Die Qualität der Nockenwelle ist schrecklich. Es gibt Spuren von Rost, man kann sie sogar auf dem Foto aus dem Laden sehen. Beide Lager waren blockiert. Ich schmierte und drehte sie mit Gewalt. Jetzt drehen sie sich, aber mit einem Knirschen, als wäre dort Sand. Sie werden nicht lange arbeiten. Ich empfehle den Kauf dieser Nockenwelle nicht.

The camshaft, for its inconspicuous price, is of very good quality on the shaft after 200km after installation only small lapping can be seen. The bearings on the shaft are of very good quality and the holes are equal to the pinion . The product is worth recommending.

The set is just what I expected. Very solid, precisely made with great quality materials. With a clear conscience I recommend, I think that will quietly serve to the end of my Yuniac.

Romet ogar 125 kit is up to 50, the sprocket is smaller but after putting more power, give a smaller chain and it flies nicely
