Ridge Reamer

[Wart]

At 50k, your motor shouldnt have any ridge at all, unless the block is soft or something. Are you certain it's only 50k, and not 150k?

Probably just some really high quality carbon baked onto the walls.

There really isnt much ridge, and yes it could be just carbon deposits. Im just really in experience and I wanted to make sure i did everything right so I was going to use the Ridge reamer just incase, cause I didnt want to mess up my pistons. Thanks Again everyone.
