Piston Change

[PedroMx]

Hi DRN:

I have a question about piston replacement, I will be putting a new piston (first one in this bike) and I would like to know if it is necessary to give the cylinder's nikasil some treatment (hone, ball hone or other) in order to seat the piston&rings.
The clearance between cylinder and the old piston is 0.07 mm and it is not showing scratch marks.

Thanks in advance

Pedro :)

Just deglaze the cylinder walls with a 3M Scotchbrite pad, then wash with soapy water.
