Well that 2nd 1k miles sure did come around quickly. Straightforward oil change again although waiting for the return oil still freaks me out even though I know it’s not starving the critical parts
Took the opportunity to check valve clearances and just as I had finished all 4 I noticed this:

Thankfully it got stuck in the oil on the casting but I think I’ve found at least one source of all the swarf on the sump magnet
Obviously I’ll not be riding it like this and I assume it’s not a straightforward job, bugger!
