Have a dilemma on my 1979 Suzuki GS 425.. During restoration, found that the right cylinder will need boring to correct a corrosion blemish from sitting for 20 years. Was able to locate apparently the very last set of .5 mm oversized ring set in the country, but for only ONE cylinder. Desperately need another set of oversized rings for the bike, and am reaching out on this site for any ideas.....What would happen if I boored one cylinder .019 over, and not the other? Need another set of oversized rings ideally.
