It was time to change my oil so I put in 5 oz's of seaform and took the bike around the block (neighbours would not like it running in my driveway for 5 min after 10pm).
After I drained the oil and removed the filter I decided to also change the oil pan gasket as I suspected that it was leaking and that now was as good a time as any to do it. Getting all of the old gasket off took a lot longer than I thought it would. I used a gasket scraper, and next time I think I'll find some chemicals to make the job a lot easier.
Anyways, here are some pics of what I found in the oil pan.
Bits of gasket material and aluminium:
What might be what's left of an o-ring? Hopefully just some gasket sealer that peeled off.
A pic of just the aluminium.
I'm guessing that the aluminium that I found is the remnants of the mess I described on this thread:
