Engine work.
Before starting, I took a bunch of photos (getting old lol) to remind me what goes where. I took off things like small brackets, buffed them up with a wire wheel on drill attachment to remove any rust or corrosion and then reinstalled them. With the easy stuff out of the way I moved on to the starter motor.
This was always one of those "did it suffer water ingress?" items for me so I got it off and found that there was mud around the outer end but due to close tolerances and a great o-ring seal, nothing got in through that end. Then I removed the 2 long main body bolts and pulled the armature out and again, everything was water/mud free. Yay!
Or maybe not yay, as getting the last part back in and holding back the two brushes with only 2 hands was freakin' tricky but I eventually I swore at it enough that it capitulated to my desire.
I cleaned up the engine surface under and around the starter while it was out so then it time to remove the head.
Now for anyone wanting to do this or adjust vales etc, I highly recommend watching and follow along with "Robot" from Scooter West's videos on YouTube. It's what I did and they are well filmed, informative and he makes doing this type of work so easy.
I got everything torn down with minimal fuss and yep just as well as yes I did push some dirt into the cylinder when I took out and reinstalled the spark plug.
That cleaned up it was time to look at the head and those valves.
The motor appears to have been running well from the color of everything but I was concerned with the condition of one of the exhaust valves as it had been exposed to water and looked rusty.
I was going to take it down to buddy Gordon's workshop but I had a think and decided I wanted to see if I could do this myself so I ordered a valve compression tool online and a couple of days later, I had the valves out and on the bench. Go me!
I got stuck into cleaning everything up and it turned out that the valve I was most concerned with actually had hard scale fuel deposits on it that had to be scraped off (actually both were like this) but I soon had everything cleaned, new valve stem seals installed and got the springs and those tiny mongrel collars back in.
I cleaned up the piston and inspected all the rings.
Then it was just a matter of following along with yet another great video to reassemble everything, some more clean up and here is the end result.
Time to get it back in!
