I pulled the valve covers, and it looks like the thing chains have stretched. I’ve been told it’s a good idea to replace the chains when you can see 4 or 5 threads on the tensioner, and I’ve got 6 (and a little play in the chain still).
I ordered the chains, and the guides that the tensioners press against. I don’t think there is a whole lot of wear to any of the guides, but I can replace that guide without pulling the head.
Should I worry about the oil sump screen? I know earlier bikes had a lot of problems with chain guide material collecting on the screen and starving the motor of oil. Looking at diagrams I can’t see a way to get at the filter without splitting the cases, and I’m hoping to keep the motor in the bike.
I’ve attached a few pictures of the guides, I’m hoping they aren’t worn more then I realize. If they are, is there a way to clean the oil sump screen with the motor in the bike?
Any and all opinions are appreciated!
Thanks!
