Garrido

Cylinder + head without shaft GY6 4T 80cm3 47mm

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

Directional air intake scooter 4T 2T red

I own a 2008 Keeway Hurricane 50/70 scooter. I bought this directional air intake to add to my scooter's appearance and to have better cooling. When I opened the package I was surprised that this product is so well made. The installation went without complications and very quickly. I heartily recommend it to everyone!

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.

GY6 139QMB 4T engine 80 cm3 12 inch 430 mm

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.

51mm GY6 90cc Piston

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

Cylinder + head without shaft GY6 4T 80cm3 47mm

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.
