Small end bearing

[kevspeed]

Anybody know if there is a small end roller bearing available to suit a 15mm gudgeon pin conversion?
Reason being,I've just dug out an old Kawasaki 150 kit with the KH 400 piston,and fancy giving it a go

You also need to think about width.

What size gap does it need to fill in the piston?
