So oddly enough, a big piece of metal from the crank case, (the actual case itself, not the interior parts) cracked off. Sick of this motor and all of its problems, I bought a new bottom end unit from ebay user boygoesfast. http://www.ebay.com/itm/191078362791?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 It was only 75 bucks shipped, which I thought was pretty good. I also have a ported cylinder coming in, so that will be my top end. I've seen a lot of bad reviews for this guy, do you think I will receive a poor quality item? I want a good running motor, is he known for having bad motors? Also, what is with the bend in the clutch arm?
