I personally feel that they are EXCELLENT engines, I know SKOOLS disagrees with me though. It is sort of like blondes, brunettes or redheads you know, different strokes for different folks. They did have corrosion problems back in the 80' that were pretty bad, but in the late 80's they got better. I know that there they have a weak dealer network in many areas, and this is there achilles tendon. Even the best of engines need servicing. And without someone who knows what they're doing doing the work, your SOL. I know many like there 4 strokes, and I'm a HUGE 2 stroke SUZUKI fan. To each there own. Some of there engines had some weakness's, but so did the other brands.
