Im thinking about getting a Chinese cylinder for my 175 and porting it as you. Were you satisfied with the kit including piston or are u using your own piston? One question about the intake. Ive got yz85 vforce reeds in my oem cylinder. Bolt holes match but they are wider by about 2mm and I did have to take off some material from the sides of the intake for them to fit. Maybe 1mm each side. I could have gotten away with less but i dont have to force them in. Do the Chinese cylinders run the oem 79-81 reed block or are they already wider?

Very happy with the cylinder. The casting is very soft, not like OEM. Also the bore needed to be clearanced or honed to the piston supplied or it would have seized. The OEM reed stops hit the intake duct so that needed to ground and clearanced.
