Ok...So you got another problem which is fine.

I need help piston hitting head!!!

So I had to get a new cylinder for my motorized bike because the exhaust manifold f***** up, so I ordered a new cylinder and piston kit off Amazon. I've got it installed but for some reason the Piston is hitting the head. Can someone please help me?

Did you solve this first problem you had then???...If so, HOW???...Were the pistons different???...etc. etc.

I notice no feedback on yesterdays "problem du jour" or how you rectified it either.

People look for that before going on to help with the next problem rather than trying to solve a new one because many often times they can be related to each other in one way or another and then you wind up with one hell of a messed up bike at the end of of it all.

Was there more "meat" between the hole and the bottom ring on the new piston vs the old? DIdn't happen to take a photo ... did you?

Because enquiring minds want to know.
