"From new it's always best long term to check ring gaps as the engine is run in at around 1000 miles and replace them if worn. We always found Honda MTX pistons would wear at 1000 - 1500 miles, the bore and piston would be fine, change the rings and they would last thousands of miles afterwards. Worn rings usually show black blow past down the side of the top half of the piston below the rings. The classic symptom of worn rings is lower compression to when the engine was first built and bad starting. But as a warning we have seen rings wear so much that they have spun over the pegs and blown up at 600 miles!"
