Ive had one time where brad didnt answer the phone. Some people have been having issues with him but everytime i call it seems to me he drops everything. Had one hiccup when i called about tie rods, but he did tell me a length and my extra yfz 450 tierods fit. Im agreeing with the guys about the case rubbing the weld, that wouldnt likely happen. Plus a guy building these motors like him will most likely not forget to little clips as i have a hard enough time trying to get mine off the main bearing in every motor i have touched
