Products reviews
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 own a Guitar Runner SP 50cc and a Rutcher scooter without this wrench the valves seemingly well set with a wrench angle and yet not what I found out for myself , it was never perfect and that's b much , lack of power and other problems of misaligned valves . Ideal for 4T scooters larger and smaller . Worthy of Recommendation !!!

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.

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!

I ordered this 139qmb engine, it fits perfectly and runs like the original from my Peugeot scooter after running in. If the mileage is the same, I'll buy it again straight away But I changed the engine oil and gearbox oil before the first start.

Arrived 3pv late and could you please correct the dimensions to be correct as the intention was to fit an 80cc cylinder with a piston and with a trille 90cm³= 80cm³ so I thought a 90cm³ piston is the same size as an 80cm³

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.
