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.

Left side engine crankcase 139FMB ball bearings

I ordered a crankcase for a Junak 902 - although it is listed as "fits to" on the item page, unfortunately it is not a perfect fit. Unlike the original, it does not have an input for the shift sensor cable.

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.

Oil Cooler 139FMB 147FMB ATV

The radiator performs very well and you can feel the difference on hot days when engine cooling is a little worse. The kit fit perfectly and there was no problem with installation. In my case, you had to tighten those nuts at the oil outflow and inflow because they were poorly tightened. Likewise, you had to buy tourniquets because the original ones did not lapped very tightly u could see the oil leak. These are penny issues and they fixed the problem.

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.

ATV 110 King Łoś magneto stator 2 coils

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.

Runs fine, pulls really well. However, I think it shakes a little when you get up to 8000 rpm, so I do not do that. I have geared the moped on the chain, so the rpm comes down. Coming down, but it can easily pull an even higher gearing if I want to go faster. Now driving approx. 85kmt
