I see the c- clip is not installed correctly. The open end should face either up or down. probably be ok. If you installed it up or down and the c-clip has rotated than it should be replaced. The rings show a lot of blow by. You put new ones in it ?

Thank you sir, I did not realize the clip was installed incorrectly, that was the way it was installed when I took it apart. No new rings, just bolted it back together with a new base gasket. Honestly I wasn't really sure what to expect as I have almost zero experience with Pilot engines. It ran well before I pulled it apart so i had hoped it would be ok to get me thru a couple of rides before the season was over. Over this winter I will pull it back off and swap in the new 80.5 i got from you or if it needs bored an 81.0.
Thank you again sir for the info and of course for your work getting us all a new 80.5 pistons made.
