boring .50 over going to affect durability?

After 4 months, I finally got my 420 back from Honda with a total rebuild.
Ive only put maybe 1.5 miles on it since I got it back ,but it seems to be running just like it did when it was new.

Based on my paper work it looks like they bored it .50 over.

Some say it may last ,and it may not.
Could it affect long term durability?

I am ocd about mantinence ,and once broken in it will get Amsoil.
Should I be worried about this small overbore?

Thanks for any feedback.

.50 is ALOT. Sounds dangerous.

If they make pistons and rings for that over size then it is designed for it and should be OK. My old Yamaha IT 175 has 6 over sized pistons designed for it.
