Starter chain guide set 139FMB 4T

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

110cc engine complete conversion from 50cc to 110cc

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.

Unlocked 4T 139FMB module

Junak 901 year 2017 capacity 49 CC I bought new. It had a lock on the revs and that indeed when it came to me this module quietly into the frame fit. Improved my motorcycle performance screws into higher revs. The quality of workmanship is very good module is larger than blocked but there is no problem with installation in Junak 901

Front sprocket 428 12 teeth

I have a motorcycle Junak 905.Its fault was that it does not accelerate in 4th gear, so I decided to buy a 12 tooth sprocket, because I have 13 as standard, so I ordered it.Once it arrived I immediately went to install it simply fit as standard. Now my junak accelerates in 4th gear.

⭐️⭐️⭐️⭐️⭐️ 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!

Unlocked 4T 139FMB module

Hello, I purchased an unlocked module for Barton fighter 50 and honestly I recommend everyone to buy this module on this site. After installation which is literally simple, the motorcycle is unrecognizable. It picks up better, it is much so called ripper and the performance is much better. I measured the maximum speed after the replacement and on the straight 95km/h passed, and I think it would have been able to do a little more, but unfortunately the straight ended. I sincerely recommend this purchase.

Piston 47mm 70cm3 4T 139FMB set

This is the first time I've ordered a piston from this site, and I have to say that I'm clearly not disappointed. The piston is in very good condition, there's no trace of scratches or anything else, plus everything is very well packaged, nothing to say on that score, and the rings fit superbly, they're not damaged or broken at all, nothing at all. I'm going to put this on my Masai scrambler 50cc with a 70cc cylinder kit.

I have a moped brand Router ws 50 I highly recommend the purchase of this module, my moped began to accelerate much faster and the top speed also increased, on the GPS without the module v-max was about 65kmh and with the module 80. The module is made of good plastic, it is larger than the original but still fits very well, I have it for about 2 weeks now and I really recommend the purchase of this product.

Ogar 900, the whole fits perfectly. Used in place of the burned out only the charging coil of the CDI module, after a slight modification of the winding connections and changing the connectors. By the way - in this stator with one coil providing battery charging, it is necessary to periodically recharge the battery!!! After the replacement so far the scooter starts without any problems.

Unlocked 4T 139FMB module

The module is a little larger than the standard one, but it fits and can be easily mounted. Electronics flooded with gel, which is a little sticky and will probably collect all sorts of flecks, but you can not see it, so all in all not important ☺️. After installation, the motorcycle gained a little power, collects better at the lights, which is what I wanted. For the price I recommend. Zumico GR 200

Unlocked 4T 139FMB module

The product is solidly made, it is a little larger than the original module, however, into the frame of Zippa Pro 50 fits. The bike got a little kick after the change, but there is not a huge difference. The only disadvantage for me is the material with which the module is flooded, it is sticky, so after some time it will collect debris, dust, etc.

Unlocked 4T 139FMB module

Fits perfectly into my Kinroad Chopper Xt50q. V max unchanged (I close the alarm clock), but much more powerful (it goes over hills it had trouble with before without problems). Replacement took me about 15 minutes, and only because of the strong tightening of one of the screws. In my motorcycle this module is located under the main seat.

Universal fuel filter 6 mm

Unfortunately I can not recommend this filter, because I got it with a defect, on the weld there was a very small invisible hole through which gasoline poured. I put the motorcycle together poured gasoline and here it dripped, and unfortunately it gave me a heap of work because I had to take everything back apart. But I'm not going to make an issue about a few zlotys.
