I'm not really sure what caused the part to fail. All I know is the welds cracked after 6 months. And with agk's setup, there are no welds to crack. I honestly wish that I'd bought from them in the first place. I didn't because a lot of ppl were complaining that agk was taking months to get parts out. This time I didn't have a choice, as Jeff would not respond to my emails and I couldn't afford any other gearbox. So I hesitantly bought from agk, and now I'm glad I did. Jeff is forever outside my bubble. sure, he got my $200, but that's all he is going to get from me, since I wouldn't buy from him again if I could. And in the grand scheme of things, $200 is not all that much money. For the record, I don't ever remember saying that form a gasket was better than a weld. How could it be, when it doesn't bond anything? Even I am not that stupid. I did use quiksteel putty to repair cracked welds around my gas tank bung, and it worked like a charm. Been 4 or 5 months since I did that, and it still hasn't leaked. People sure do waste a lot of energy being ****ed off at me and being happy to see me having problems though. But oh well, that's your problem, not mine. I'm living my life the same, with or without some Internet knuckle heads in my corner. If you think for one second that your opinion of me affects even a millisecond of my life in any way, just keep feeling that way if thats what it takes for you to feel good/better about yourself. I'm like a tank, I keep rolling regardless. 30 years on this earth and many people with that same opinion, and I'm still rollin'. In fact, I'm the happiest I've ever been. I'm not so pathetic as to be built up or broken down by the opinion of someone behind a computer screen, and many times not even by someone I'm face to face with.
