aint_skeered

hahahaha I'm willing too just kinda not looking forward to it, I've been so busy lately and I just don't wanna tear it down and leave it open, guess with great sacrifice comes great reward, I just don't get it though cause I hammered this bike the other through sixth screaming and I'm thinking if it were bearings that she would have went ya know, but for my own comfort the best the to do is tear it down and while it's down just rebuild it and be done and maybe go with the 4mill set up whatcha think?

My bike had a slight knock to it for awhile sometimes louder than others, one day the knock became loud like maybe a crank bearing or rod bearing failed, I set the bike up for a couple months pulled it out started it and no knock, put new plugs in and the bike has never been better, any pointers on what it might be or what should my next step be?
