Cylinder and piston good quality but rings unfortunately not. After 150 km of mileage the gap of the rings after inserting into the cylinder was 3.2 mm Yes does not lie. The engine did not smoke but did not have its power. The solution to this was to put on rings made professionally from good quality materials. The cored rings lasted 13,000 km in a Chinese scooter. In my opinion, it is worth it to buy the made-up rings for 40 PLN than to take apart the engine every 2 weeks.

Moto: WSK 125 gil. Changed ignition to cdi, after a while wire of ignition coil in stator broke (find out after disassembly). Somehow i didn't have removal bolt for cdi rotor. Bought this one, fit perfectly, removed cdi rotor quickly and effortlessly. Good tools not only make life easier, but often is the only option to acomplish the task. I am happy with the purchase :).

I have been buying parts from gmoto for several years and I am very satisfied with the quality of the product, as it is made very solidly and aesthetically pleasing. The shaft protector that I recently bought fits perfectly to my 139qmb 4T engine

It's OK. Suitable for Kymco agility without problems. Otherwise just a standard aluminium cover - use half the official torque, exhaust manifold bolts preferably 5 Nm tighter than the recommended torque, etc.

Head of poor material, fit to the serial cylinder.tragedy, valves had to be tightened because they barely held. Lots of filings were needed to clean everything.

Zumico Quick 4t 50ccm. The set fit perfectly, the only remark is that the set was missing the bushing seen in the photo, which I replaced with the old one. Overall I recommend :)

Gmoto's reply In the product description it is indicated that the kit includes the starter pinion and kicker and there is no bushing. We have updated the photo and it now shows the actual composition of the kit.

Hello, I bought the head for my King Way Ibis scooter due to a torn spark plug thread. The head fits great and after adjusting the valves the scooter runs nicely again. Thank you!

Motobi Huzar 4T 50cc. The product is solidly made. It is not a cheap Chinese product. Precise dimensions contribute to fast and trouble-free installation and operation.
