I installed this kit on a Romet ZXT 50 moped (vintage 2019), and it works perfectly. The biggest challenge with the installation was changing the timing chain and replacing the engine pins with the ones included in the kit. To change the chain you need to: 1. remove the magnet wheel housing so that it shows whole, as in the attached photo. 2. you need to somehow lock the magneto wheel to unscrew the magneto mounting screw. I was able to do this with a filter wrench on a strap that I found at a DIY store in the car section. I tightened the strap, and held the plastic handle in the opposite direction from the direction of unscrewing the screw with a regular wrench. This required a very large amount of force, but it worked. 3. after removing the nut, use the tool for removing the magnet wheels on 139fmb engines, available here on gmoto.pl. Screw it on, and then tighten the bolt firmly. This also required a lot of force. Next, we remove the magneto and be careful not to let the starter clutch pebbles fall out of it. 4.We remove the starter with the chain (remember to pull off the metal protection first. 5.Then we unscrew the screws to get to the timing chain. On my ZXT 50 model (2019), there were very strange screws and I was forced to force them out with a larger bit and unscrew them. Of course, I had to replace these bolts afterwards, but there are super bolts available here as "Seal cap bolt". The second problem was unscrewing the old pins and installing the new ones. Without special tools, this can be easily done by screwing in 2 size 10 nuts. And the one closer to the engine hold with a 10-gauge wrench, and unscrew the other one. The same way you can screw them on. The cylinder and head work great, there was a set of gaskets and spare valve seals. For this kind of money I highly recommend it!

Hi. I purchased this product from your store at first I was skeptical because the price was very low but when the package arrived I was very pleasantly surprised by the quality of all the components and their fit also the whole kit was complete and ready for assembly. At the end I will add that everything works very well my bike got a second better life :)

Zipp Neken 50 4T 2017.Just a bulb,and very happy.There is a huge difference in comparison with the factory-installed Ba20D.Mounting trivially easy and more convenient,because there is a much shorter base of the bulb.Perfectly copes.Greetings and thanks.

So the product is of mediocre quality, it's very rough, there's play everywhere and the segments supplied don't correspond to a 110cc but rather to an 88cc. I absolutely do not recommend this product.

- very good value Moretti kit. - fits the 139 fmb engine for magpower r-stunt the chain and cylinder pins sold in this kit are essential because the kit raises the cylinder+head assembly by about 4 to 5 mm so the original chain and pins are too short. - be careful with the 4 pins, 2 are longer to fit or the 2 cylinder guide spacers have to be fitted as they fit into the engine block. - as already indicated in other comments, this kit is complete except for the oil seal between the cylinder head and the cylinder, which is not supplied. - For your information, in my case, the original 50cc starts on the fly, now with this kit I haven't managed to start it yet, but I think the problem is that it's a Euro4 with an ecu and an electric injector, so changing the original MEV1-030 A injector for a MEV1-080 injector to bring in more fuel still doesn't start, I think the ecu needs to be re-mapped, I'm continuing my research to make it work. I'm going to miss the good carburetor that was so easy to change for a bigger one.

To make it all have arms and legs we will start from the highest to the lowest rating. Aesthetically everything looks very good :) The quality of materials I do not rate excellent because such is not (when trying to mount the cover to the front sprocket, the cover broke under not much force). The fit of the materials to the kit was the weakest, partly due to a packing mistake which can be forgiven, of course, but the biggest problem was with the valves. After adjusting to 00.6 and 00.8 (intake and exhaust) and driving about 20 km, the valves were in worse condition as originally installed from the previous set installed 2 seasons ago, the outlet in the head for the muffler is too narrow and you need to install a washer, grind the outlet in the head or grind the muffler. The set was missing the orings. After replacing a few parts from the old set to the new set, everything laughs and even better as I wanted The fault does not lie with the store, but with the manufacturer, who gave asses

Hello My vehicle is a 2008 Kinroad Sprinter. Its engine capacity is 50ccm. Unfortunately, it is not a speed demon .So I decided to purchase at Gmoto.pl store, a full set to increase the capacity of the engine ie: head , cylinder , piston , rings , pins, etc. from 50ccm to 110ccm. After the installation of the purchased parts I am very impressed,the quality of the material from which the parts were made and the fit of the parts.Everything fit very well .So the installation of the parts was very fast and pleasant.Now it remains for me to calmly reach the engine and then we will see what this beast can do :) I really recommend the product and the store . Greetings Dawid

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!

Probably the best set on the internet ! I looked everywhere, but such a complete set I have not yet found anywhere ! Take it while it's warm :D And while the price is so low :D

Howdy.I purchased a 11 tooth front sprocket from gmoto.I was surprised that I only paid 10 zloty for this product as it is from a decent company.I own a street 50 moped and there were no problems with the sprocket.It fits perfectly on a 428 120 link chain.According to me,the power seems to have increased a bit but the v max has decreased.If we try a bit harder and shoot the clutch we will be able to ride on 1 wheel.I warmly and sincerely salute g moto for their excellent and quality products.

The cooler looks to be of good quality. The only downside is that I'd have liked several types of fasteners, because I'm not sure the two metal lugs will hold up over time. They look like cheap aluminum. And there's no silent block supplied to dampen vibrations a little for the radiator. After that, I'm a handyman, so no worries for me. Assembled in half an hour. Would recommend.

I received a complete set, nothing was missing. Quality and workmanship at the level of the original parts dismantled, with the fit was not the slightest problem either. Only mark on the head the one for setting the timing, a little faintly visible, but after 5 minutes found, and as if someone also did not notice it is on the outside at 8 o'clock

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.

This tuning kit, which I purchased from GMOTO store, turned out to be the best in terms of: price, workmanship, fit, and aesthetics. I assembled the whole tuning kit there were no problems with it, very easy assembly. Now I am waiting for everything to arrive. I heartily recommend GMOTO store, and of course this tuning kit 110.

Cool actually finished kit. In the store I got the information that there is no need to replace the shaft (as long as the previous one is in very good condition), and indeed it is. The piston does not reach the very end of the cylinder, but the compression is good, and the gear works, so for me it is ok. The sound of the machine has also improved significantly.

Quad ATV 110, I do not know from which year but somewhere around 2003-2007 Very good quality product everything fit like the original, there were no problems with installation. After installation the starter finally worked ;) Sorry but I did not take pictures :( I did not have time to do so because the children already wanted to ride the quad

Now my starter is working properly I bought this because I ran out of brushes and I often use the starter through an electric starter to start the engine, as for the price it is worth it and as for the difficulty of assembly I rate 5 stars for a layman in my opinion it is trivial but, as you know, it happens differently Greetings :D

Junak 902 2011r when replacing the cylinder for 110 you need to change the crankshaft power is greater as well as the combustion, but it is certainly better to have 110 than 50 through which even in the sand will not pass. When installing, be careful of the threads in the head because it is not too strong material you need to tighten in moderation.

The quality makes a very good impression. Shipping was very fast and everything I ordered was securely packed. Really helpful for installation and removal. For me, 1000 times better for the price than sending the nut off with the hammer and driver.

Hello, The valve clearance seems to be of good quality. Only the exhaust valve head is slightly smaller in diameter than the original one. See after running in if the contact surface is sufficient. Gmoto, a responsive team and fast delivery. I recommend Gmoto.

It is a complete set which fits perfectly and I had no problems with fitting it, I didn't even need a file to scrape off the excess casting, as it happens in such cast parts. I ride with it to this day, which is about a year now, and so far it promises to be great.

I own a 2020 Apollo Avenger 125 Quad the sprocket was easy to install and I think it is made of durable material. It looks pretty good for the price, and fits like a glove. The 12 teeth fit perfectly, the chain is not too tight and the quad has better performance.

The kit complete and at first glance solid, castings made nicely, the thing that pleasantly surprised me was the spark plug in the kit, which was not in the description. The package came quickly and efficiently, now just to put it together and go! :)

Moped - Barton Fighter Eco 2020 This is not an oring for 139FMB !!! Too small in diameter and too thin. 139FMB has an ebonite washer with a passage diameter of 20.5 mm. This oring, on the other hand, fits a different washer, with a passage diameter of 17 mm.
