for the takers, piston pin to deck is exactly the same so piston do not sit further down.
this kit is sold as a "direct replacement for dio motors, AF18E", so i dont see why in the * i would need to bother with such off spec stuff like that.
Cylinder height is exactly the same as the original dio one too.
So to me, they just machined the top and bottom of the cylinder 0,1 off the center, thats it.
I will make a shim of the proper thickness and mill the deck down. This will bring the all the ports as the same place as the dio one, and once i will mill the deck down, it will bring back compression ratio up.
Rest of comment are around ensuring that the kit will work. The idea that most folks working on these bikes would check port heights, etc, post installation is optimistic in the extreme... most kids won't even check the running clearance before trying to fire it up. If they get all four bolts tight on the head it's considered an installation success.
i didnt admited i bought the cheapest kit, i bought the one i found. i contacted the seller and he said there might be issue with machining, giving him the fact that i sent him pictures with measurement details compared to the DIO cylinder.
