GOOFIT 57.4mm Cylinder Head Assembly Valve Replacement For GY6 150cc Chinese 152QMI 157QMJ ATV Quad Installed Scooter Moped

So some of you may be confused. Here it is.I ordered this because my 125 scooter decided to pop a valve and blow a hole in the top of my piston, smash the bearing up on the camshaft and rip the rocker arms to bits on the way home from work, leaving me stranded on the side of the road for 3 & 1/2 hours awaiting recovery. In a desperate rush to get it rebuilt I ordered the only next day available piston and barrel, and head. Not 100% sure if this was for a 125 or a 150 I ordered it anyway. Turns out this is actually a 150cc barrel and piston.Which means: if your just looking for a 125 piston and barrel this isn’t what you want.If you want to go for the 150 like I did, well had to, you need to buy the head aswell with the valves (another £30) but then make sure you buy a valve cover also. As the head is non egr valve meaning the cover you have won’t fit.All in all, my bike runs mint now, not sure why people said you had to mill it as it slid straight together nicely. and don’t buy the goofit camshaft as they send the 50cc one which isn’t long enough, unless you bodge it like I had to untill one comes from eBay.

It's a good quality item for the price

Everything seems good except when i checked the valves to see if they were seating properly, i noticed they were not. Had to lapp both valves. No big deal. Easy job. Just letting people know this. Thats the reason for 4 stars instead of 5.

Für meinen Roller genau die richtige Wahl.

Nel mio caso la valvola di scarico si è allungata a dismisura fino a staccarsimdallo stelo e rompendo pistonemtesta e graffiando il cilindro.non buona.
