cam wear

Hey all!

So I was doin my yearly valve lash adjustment on my 09 te310 and I happened to notice some odd wear marks and I was wondering if anyone else has seen this before. The bike has 2100 miles but some of that wasn't recorded bc the previous owner broke the speedo cable and never replaced it before I got the bike. I checked the hours when I bought it with ibeat and it had like 60hrs on it or something like that. It probably has more like 80 now but I haven't checked since. Anyways, I'd appreciate it if someone with a history of rebuilding these motors could chime in here. Btw, I think the marks may have something to do with the retaining clip between the followers.

I'll admit it looks slightly weird, but OTOH- it's on the base circle and not the lobes right? heat treatment maybe? I don't see an issue.

Maybe BT will chime in- I think he built engines in gas drag cars or something similar.

Looks normal to me. The follower rides on the cam it's going to shine it up eventualy. Check your clearance and run good oil.

I don't think it is an issue, I would adjust and run.

Thanks for the info guys. And being that these are line bored heads it would be a total nightmare if the cams went lol
