Pistons have some carbon build up and some skirt scuffing nothing deep or that bad and my cylinders are good so I don't need a bore. Can I just chem dip these, clean them up and reuse them. Bike has around 10,000 miles on it. New STD size pistons are kinda expensive...more than oversize it seems. Should I just buy oversize and bore rather than clean up the old ones? This is my first top end job due to a leaky valve seal and would like your opinions on reusing pistons vs buying new ones
