Kazimierz

I put a 110 engine into a 2013 Barton Fighter 50 eco. The engine started and runs well.Not matching are :front sprocket(the 14-tooth one seems to have a different pitch because the chain jumps) , gear shift lever,foot starter and sprocket cover ( you have to cut it to fit ) . You also need to replace the air filter in addition. Another thing you need to get used to is the gear layout - neutral at the highest and the other gears down ( N-1-2-3-4) .You also need to put an additional line to the suction because in the previous carburetor there was a lever control directly on the carburetor.And besides, there is power :) . Greetings.

The kit itself is ok. I will be installing it soon. The kit is complete and everything seems to be ok. I only have a reservation about the packaging of the goods. The head and cylinder came in one big box. It looks like the head must have been badly packed because it punctured the box and has small scratches at the exhaust mounting entrance.

It fits P&P to a 139FMB engine from 20 years ago, so there is nothing to complain about. However, the quality could be a little better, I would be willing to pay extra to get a better made product, other than that, you can take, put on and lapped.

I ordered this set for zipp shocka 50cc with the idea that the power of the moped will increase but when I ordered it I did not believe that this set will add such a kick :) Now I do not recognize the moped and the power is already sufficient for me .From the hand on my heart I recommend shopping at this store because the products are very durable and made of very good materials so the quality is amazing, I happen to be satisfied with purchases here because what I order it comes and sometimes the store throws in a freebie which I like very much.So once again I recommend people buy here and not on some other sites such as allegro because there you can get equipment of Chinese manufacture which results in a short eternity of goods I not once or twice ordered here and always satisfied and more than once I will shop here :)

Zipp Pro 50 2012. The purchased kit significantly increased the power of the engine. You can feel a big difference in a few years old Zipp with 50siatka. I have my pz19 gasser, at Gmoto I bought an 85 nozzle and zembatke 16 for the front. It's in the running in so I haven't checked the max speed, but already on low I can feel the torque and power, and uphill it stopped slowing down in 4th gear ! Moped turned into a motorcycle Very well made head and piston. Cylinder also super. Everything fits and is super made. Nice and aesthetic. Good for a gift !!! I recommend this set to anyone who lacks power or needs to do an overhaul of the 50 grid, and is afraid of mobtaz 110. Installation of 72 very simple, everyone can manage on their own in the resource with two screwdrivers and open-ended wrenches 10 and socket 13

Engine received quickly, there was a lot of oil in the box but that's because of the carrier, otherwise the engine is great, I mounted it on my masai greystone 50 and it's really plug and play, you just have to connect the cables. On the other hand, the double-branch gear selector doesn't fit on the masai greystone and neither does the kick, so I kept the ones on the original engine, but otherwise everything fits perfectly. I'm really satisfied with the engine and with Gmoto! I highly recommend it!

⭐️⭐️⭐️⭐️⭐️ Top motor - absolutely recommendable! This is now the 3rd engine I have installed - and as always I am completely satisfied. The price is more than fair for the quality on offer. The workmanship, performance and durability are impressive across the board. Shipping was super fast, everything was well packaged and arrived without any problems. I can recommend this engine to anyone who wants to make their moped faster and more reliable. A clear recommendation to buy!

Cylinder of good quality. Head assembled and ready for installation. Cylinder + head fit all mopeds with 139fmb/fma engine wiec so it is good because the product is kind of universal. The only downside is that the packaging of the cylinder came a little battered, but inside these elements were wrapped in an additional foil boom wie więc probably something in the courier company happened. Anyway, I recommend it, I've been riding on it for a while now and nothing bad happens.

Hi . As I was about to increase the capacity and dynamics of my moped I saw a 72cc kit so I decided to buy it . After putting it on and after 50 km on the run-in I do not recognize my moped, this kit guarantees everyone to increase its performance sufficiently. In summary, I recommend it to anyone who cares about improving the dynamics and comfort of driving their unicycle ;) .

Kit quality revelation for this price . Unfortunately, when it comes to the head itself, the shaft with bearings walked loosely and had to be corrected, as well as the valves are not tightened and need to be readjusted preferably before assembly. There should be an additional notice to check the heads carefully, because there can be such problems. Other than that, the motorcycle runs sensationally after assembly.

chopper kingway 50cc 2007 I bought this kit to improve the performance of my motorcycle, I am still in the process of lapping the cylinder but after a slight addition of gas you immediately feel that it has more power so after lapping and proper adjustment of the carburetor should ride at a speed of 100k / h The product is high quality worthy of recommendation to anyone who wants to increase the power of their motorcycle

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.

I've now tested this 72cc engine and unfortunately it didn't quite live up to my expectations. The top speed is around 50 km/h, which is a little disappointing as I was hoping for more. However, the engine works fine and does what it's supposed to do, so if you don't need more speed, it's an okay choice.

Everything is fine but I have a few reservations if it is sold as a complete set then it should also include pins for the manifold well and there should be lapped valves and not now you have to disassemble to reach the valves and it would be better to pack such things so that there is no slack in the package.
