Surprisingly, the rear bearing wasn't too bad. There was no roughness when turning it and it still looked pretty good. The only thing I can think of for the lack of wear, is the Rapicon fuel I'm now using. Must be good oil in it. The front bearing is usually in good condition, but this one was a little rough though.
The plug is the original too. 183 flights, so pretty happy with that.

Front and rear bearings and all gaskets and O rings were replaced. I didn't replace the cam bearings. The ring was OK too, so left that in for another go. Even though the plug was still working fine, I replaced it as a matter of course.

It's back in the Xareltoo now, ready to go when the weather is favourable.
