So I get a phone call today from a guy that has an engine issue. He has a knocking sound coming from his motor and wanted me to help him out if possible. The bike was making a knock from the top end. A 2006 GSXR 750 The sound is now in the bottom as well. The video is of the new oil that came out of the motor. The pictures are of metal flakes coming from the exhaust pipe. Yep, the exhaust pipe. The bike still runs, is low on power and shuts off every half mile. It also over heated by 50 degree and was spitting coolant all over from the overflow. The bike will show up Friday and I am going to take the valve cover off first. I'll post some pictures as soon as I get the bike and start working on it. Long story short. If it is making a abnormal noise, DO NOT run it for a half day and hope for the best.
