No, I'm not sure. But I had it apart last winter partially due to hearing a noise I didn't like and thought I found the problem with a damaged small end bearing. I ended up getting a decent crank with excellent rod bearings for ebay and had Hugh rephase it. So both Hugh and I checked it out and it looked OK. In the process I honed the cylinders a bit and put rings in it but neglected to check the piston clearance (dummy me). So this season the noise was now louder, oil consumption is up (new valve seals too) so things are pointing to piston slap due to excessive clearance. I also recently checked compression and it is down a bit especially in the left cylinder and that is where it sounds like the the noise is coming from.
So I won't know for sure what I need to do until I tear it down, at this point in time I'm investigating my options. I did contact Gary and he thought at 65K miles I got my money's worth out of the pistons. One question comes to mind, what is the likelyhood that the bores are OK and I just need new pistons? Never did that before but nowadays money is tight. :-(
