Anybody?, I have got my raptor tore down now, the still has somelight cross hatch on it, there is a 1/4 black ring around the top of the cylinder and prob a 3/4 ring around the bottom where the weAr is different is this normal? Can I just use break cleaner and a white scoth brute to get rid of the top ring? Do you just scotch Brits up and down or do you have to try and follow the cross hatch?

As long as the nikasil plating hasn't worn through, you can clean it up with scotchbrite/brake clean. Basically you are just de-glazing it. Can you post a pic of the cylinder?

If you haven't seen the "how-to" section, you should look through it. There is a link to download the service manual there as well. Take the time to read through the engine section of the service manual. It will walk you through the piston install process.

Here's a link:

Got my cp tech piston installed and everything back together but was wondering how do y'all recommend I break it in?
Some go with the " break it in like you ride it" method or there is the try not to go over half throttle for 2 tanks of gas method. With the latter method you should also not hold the throttle in one place for long, it needs to vary to help seat the rings.

scotchbrite is not really the way to hone a cylinder...lol. your bike should run fine probably, but a quick ball hone job would have been way better. a proper crosshatch is a lot better start on a new motor...
