My '91 KDX200 is becoming more and more difficult to start and smokes heavily once it is started, so... Compression checks in at around 120 psi after about seven or eight kicks. This being the very low acceptable value according to my factory manual, should I expect just a ring job, or maybe a piston, ring, cylinder replacement? I know you cannot bore out a cylinder on one of these without having it plated afterward. Any advice or suggestions on the best way to do the repair? Thanks!!
