Pulled the pipe off my 03 rm125 and took a look at the piston and noticed this little line on the side of the top of the piston, I ran my finger across it and couldn’t feel it. It’s a weisco piston with approx 5-7 hours on it. Should I replace? Photo

Engine was Rebuilt by previous owner at a shop. He did the break in, hoping I don’t have to tear it down.

i would put in a new top and inspect the cylinder for damage, you could more than likely get away with a new piston and a hone
if you run it you will be at risk to blow a whole top end

i would have your local shop hone it
and check your power valves no make sure they are not scratched, if so hit them with some sand paper as well as the exhaust ports
