Quick question. Would it be wise to buy new rings or a new piston and rings kit?
$30 - rings (74mm bore)
$75 - Piston, rings, cir-clip, wrist pin (74mm bore)

My cylinder is 250cc, 1st over on the bore. I measured it at an average of 74mm inner diameter last night, pre-honing. Will honing it increase that any (I have my own tool to hone.)
There doesn't appear to be any blow by or bad marks on the current piston so I'm leaning towards just new rings to keep well under budget with this clean up.
