I need to jump in here (even though I know I'll probably be getting in way over my head). I've read most of the forum's 62mm S/C pulley posts and I understand the concept of the redesigned pulley along with the quest for faster acceleration. One post referenced "does it fix the problem" which I took to infer that I might expect a problem with the OEM S/C pulley down the road? Questions: 1) Is there an inherent problem with the OEM pulley? 2) There are many references to the fact that the various 62mm pulley offerings might not be available in the future. Even though the increased speed / engine power modifications are way down on my priority list, should I be moving to get a 62mm S/C pulley now while they are still available? I realize that this new E-Bay pulley offering is still untested but of the others that might be still available in the marketplace, which one is the best design and provides the best results. Thanks for sharing your expertise and pointing me in the right direction on this issue.
