Ok how many of you have blown up the KA in your 240. The reason I'm asking is that I've gone through 3 KA24E's in less that a year and I'v noticed a trend that every one has blown after the chain guide failed, even if I replace the chain guide right when it breaks within like 3000mi the #3 rod starts knocking. If any one else has this problem please tell me because I'm starting to think I'm cursed or some thing.
