I have a 2002 kx 250. I want to do a rebuild on it. I can't decide whether to do a single ring piston or just the regular 2 ring piston. What do you think? How much faster does the single ring piston make it? Does the single ring piston not last as long so I will have to do a rebuild sooner? How much longer does the 2 ring piston last over the single ring? Is a single ring piston worth it? Thanks!!!!
