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!

Junak 104 2T 2013 Very nicely made cylinder for reasonable money If someone gets clogged with a serial cylinder, an interesting solution is to buy this cylinder, for this nozzle is 0.10 more than before and for a little money we have a really dynamic equipment I have already driven 2500 km on this cylinder without any reservations Please do not expect a colossal difference in power compared to the series in my opinion, thanks to this cylinder significantly increases the torque and a little power at higher revs. + Good price + Relatively good performance + Inexpensive way to increase power -Very loose rings which makes it hard to put the cylinder on (once you put it on they come off very nicely) - Sfloor locks are difficult to turn (the push-in ones are better) - Too bad there is no exhaust gasket in the set Final rating: 9/10

I received the cylinder ok, but for the cylinder head : - No spark plug screws to be replaced, - bent exhaust valve and valve gasket out of order (recommended elsewhere), - major machining work to make it watertight. The intake pipe is too short to fit a 139 FMB, so it's useless. The paper gaskets are also of very poor quality, as are the piston rings. Very disappointed with my purchase and no possibility of complaint from France. Chinese parts of poor quality, next time I'll go directly to ali for this quality.

Scooter inca street 50 year of production 2009 mileage of about 14000 I ordered a cylinder + heads 70ccm reason to reduce fatigue of the engine, after opening the box with the parts I started by inspecting the workmanship, I watched all the channels in which there are in the cylinder the workmanship itself is very good, the very tinkerer went through very easily from disassembly after assembly it took me 40 minutes if anyone has the idea to repair vehicles themselves it will do it in a similar or shorter time, currently taken picture is not fully visible but they are newly purchased things

I have bought many top ros cylinders from you, or the same model in black or grey ... the pink ones I repainted in grey for discretion ... very good value for money ... I prepared a few bikes for young people who really appreciated the performance ... unfortunately I don't have any pictures ... ke can take some disassembled cylinders and I'm going to reassemble one because I've just tightened a most 86 ... I mount them up to 88cc with vilo C45B90

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 :)

Product as described. Fitted to a Eurocka GTR-B 50cc. I changed the valve clearance. The original valves had too much clearance for the kit to work. Normally intended for a kymco (I didn't test fit a kymco agility 50cc). I've driven over 1000km with no problems. Big power gain 20km/h

I recently tunigowal a scooter zipp astec used to be 50 now 80 ccm3 year of production 2008. I bought a set of head cylinder piston rings and everything needed. The quality of the parts was at a very high level. The piston perfectly matched to the cylinder. When assembling the engine on these parts there were no complications.

Hello I own a quad atv 110.The build quality of the kit is very good. There was no problem with fitting and assembling the parts. There is only one drawback in this kit that there is no sign in the head to set the timing. But the one who knows what is involved in assembling the engine will manage without a problem. I highly recommend it.

I have an Aprila mx 50 so I bought this product due to the reasons of the seizure of the previous one, which was already when I bought the motorcycle and I recommend this product works well and to keep it that way longer. I don't have pictures of how it sits now but I am mega satisfied.

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

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

I own a Husqvarne/CHRacing WXE 50 with a 2007 AM6 engine. Unfortunately my cylinder was seized and with help came the Gmoto website where I could buy the same cylinder but from WM Moto instead of the predecessor (NoName).The difference? The one from WM has a better fit of the piston and ring after measuring the gaps.Its channels are more precisely made (on the predecessor there were pieces of casting left).The price as right,I highly recommend the product.

I bought the cylinder, piston and head for a 2000 CPI Hussar scooter, changing the factory 50 cc to a purchased 70 cc. Visual assessment of the quality of materials and workmanship is not objectionable. Both the installation and the first start-up without problems. The piston and cylinder are only in the run-in phase, nevertheless, the performance of the engine is flawless, and the power has clearly increased (assessed in terms of top speed).

Zipp Quantum, good quality cylinder, very good price. In general, I recommend so far everything rides like from the factory and I hope it will serve a long time. The scooter is much more dynamic, v-max has improved. Riding has become much more pleasant than on a 50cc I really like Gmoto store because I can order many different things with one shipment. And as for the cylinder I highly 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

"After installing the 70 2T cylinder and head in my scooter, I immediately felt the difference. The scooter has gained power and acceleration, which makes riding more dynamic and satisfying. The solid workmanship of these parts gives me confidence that they are not only efficient, but also durable. Now I can enjoy a smoother and more exciting ride!"

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.

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.

Good product, easy to install, very good torque at low revs, but a higher piston-cylinder clearance would be better because I had to tighten it several times. The piston was scratched in the administration area, but the cylinder didn't get any milk for the price, so it's a good product.

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.
