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, it wasn't too bad for the hobby project.

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.

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.

very good quality cylinder head, adds power when the engine revs up, which can be felt on acceleration and top speed, gaining at least 10km/h if you add an A9 camshaft or more, you'll gain even more, that's for sure! Perfectly packaged .thank you Gmoto .

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

Nuts at an excellent price for 4 hard replacements for the original exhaust mounts on the Honda XR 125. Excellent value for money and a compromise between the original ones difficult to find only in Honda service, for a much larger sum! Highly recommended! 30 years of experience in mechanics!

As for the cylinder head, unfortunately, I have a big minus because after installation it turned out that it is damaged (microcrack) and oil leaks from the engine onto the exhaust pipe.Valve keypad and camshaft ok with no complaints.

Brok on piston and channels price very good for the quality of the product as much as possible I recommend along with the head 90cm3 may appear collision suggests to collect some material from the piston or house a thicker gasket

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.

It fits, but the quality of workmanship is very average and it is a pity that there is no exhaust gasket, which is sorely missing No exhaust fumes fly by the row because there is no even plane.

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.
