hopefilly it’s nothing. Got two track days coming up in under 30 days a piece

 

When’s the last time you adjusted valves? Also check your oil level. Make sure it isn’t low. Other thing comes to mind could be chain guides.

 

Typically clicking noises will be attributed to needing a valve adjustment. I do mine once a year actually!

 

~40k since last adjustment. I've read that the valves could stay in spec for 100k?
