Hey guys,
This is a copy post from my build thread but really haven't gotten much feedback so I'm reposting here to hopefully get some answers. Anyway, I bought this 1988 GSX 600 motor recently for a engine swap project. I wanted to take a look inside before pulling the 550 in my '82 katana. The motor had 11k miles on it. Looked clean except for the following cam lobe. There's one other cam lobe that has the streaking but no pitting. Both are on the exhaust cam. I'm just trying to ascertain if this is a metal defect from the factory or something caused by neglect or abuse and is the cam shot or can it be run like this? I did a search on the net a found only a couple of threads with varying answers. If it's a metallurgy issue then I feel better about it. If not, then I'm probably going to have to open the engine up even deeper for inspection. Thanks for the input.
