Tuning cylinders

I bought 2 sets of cylinders. There was nothing wrong with one of them. On the second, the liner was honed at an angle. In the upper area of the liner, an approx. 3 x 5 cm area was not covered. One piston had the recesses for the valves milled at an angle. See photo. The other is obviously already an oversize piston. As I have access to appropriate machines,... more

I installed in a 2010 Barton Fighter moped. After mounting the moped clearly came alive, it became very sprightly, the top speed also increased. After starting from first gear it can sweep the wheel, and after releasing the clutch faster it stands on the wheel, also when shifting to second gear the front end likes to lift gently. Overall, for this price I ca... more

I have now bought this product for the second time as the piston was damaged after a short period of use. In contrast to the first delivery, the piston was pre-assembled with rings and the upper piston rings are now clearly different, as they should be. The first delivery came with two identical copper-colored piston rings, which probably caused the damage. ... more

good product but I have the impression that it is less efficient than the cast iron which costs half the price ... besides I hesitate to recommend a cast iron one ... in any case, it's strong, personally I never do a real break-in, hardly a full tank and on a scoot with a well-tuned variator, you can't limit the engine speed ... always full pot! :) it doesn'... more

Aprilia SR 50 AC cylinder fits very perfectly beautifully made nothing sticks out no blemishes on the outside no ducts can be seen no holes nothing sticks out inside which greatly affects the quality and flow resulting in smooth power output and life tests but the predecessor of unknown origin seized up after 10 km deflated like a balloon

Hello I naprowiam skutrey,Qady etc.Ordered parts really are OK . If you order a good part, it rather has to fit, personally as a mehanik I recommend cylinder 65cm for GY6 4T IS in my opinion the best, fragile, 50 has too little power, 80 can take oil in a short time exploatation Greetings

I bought this product not long ago for now I'm still lapping but already a lot of cool things I noticed such as very good fit, workmanship very good and with good materials and in addition cheap. The power gain with the 95 nozzle and Gianelli Extra VW exhaust is unbelievable. I sincerely recommend it highly.

Very good build quality. The head with larger valves to this plus the replacement of the main nozzle in the carburetor gives incredible power. And if you replace the gearbox with more teeth in the engine it flies like a storm. 2 times faster and much more powerful. I sincerely recommend. I have taken a lot from this store and everything great.

Cylinder solidly made. With the ring channels worse . I family well lubricate with oil . Because it went into the channel for me and stuck . After lubrication it was all right . After assembly and test drive was felt a very big jump in power . I recommend to all who do not like to overpay .
