Cylinders?

Ok been a while guys and gals. I have been doing some searching and cant find the correct answers.
I have an 03 rc51. And am going to do rings (already torn down) are the cylinders plated from factory.

I have seen mixed thoughts on giving them a hone vs bore.

Has anyone had any luck with just givibg it a hone job as I really dont want to send it out if i dont have to.

I havent ridden it in about 4 years.. I miss it lol.. It was smoking like a siv before putting it away. The cylinder walls dont look horible but still need to do a bore measurement. already planning on doing valve seals.

Thanks again

You will need to have the cylinders coated with nikasil.

The cylinders are not Nikasil plated from the factory, the alloy is impregnated with a Honda proprietary compound and honing is a specialised process and (in my country at least) not cheap. They wear fast. Honda make .25 mm and .50 mm oversize pistons so over-boring is one option, however if I was in the US I'd send the block plus a pair of stock size pistons (OEM or JE 11.1:1) to Millennium Technologies and have them plated to the ideal tolerances.
