    • Are they the same as the one Will Spelta has Michael Oneill

    • Will what Pistons are u using and do u have stud issues

    • Sleeves don't cut into stud holes,motors aren't running yet.Might go boom or bang Joshua Adam Sligar

    • It just looks like your studs might not fit that's all, I hope it stays together mate

    • Should not be a problem with the right rings, you just have to go with the muffin top style in double oversize.

    • 49cc one..

    • Just buy a bigger piston

    • It's a postie it'll definitely run like this...

    • I asked a local mechanic, and he said that fit is normal, as the piston will expand as it heats up. No worries, ride ride ride.
