50mm Engine Motor Piston Pin Set For 100cc Motorized Bicycle Bike Motor

This was a bit of an impulse buy I havnt installed yet because im not decided if im using the single piece jug that came on the motor or converting over to the ld100 2 piece i got same time i ordered this piston only gripe is i didnt happen to see in listing if it was a high or low hole piston i guess that twill decide which setup i use or most likely the fact some of these engines have different connecting rod lengths will more than likely decide if i will or will not be able to use it on this build
