    Good items to replace while top end is off?

    Simple question. If you don't have any advice keep scrolling.

    Good items to replace while top end is off?

    The roughness seams pretty excessive for a manufacturing process. Could it be from sucking dirt through the carb? I’ve never seen a piston with this much pitting in it so I’m just curious.

    Good items to replace while top end is off?

    As I’m doing my first valve replacement on my own on a 2003 Honda CRF450R that I’m bringing back to life I noticed that the piston has a rough surface around the outer perimeter. Im not sure if this is just how the stock piston looks (I wouldn’t imagine that it would be) or if it’s a result of detonation, extreme wear, etc. Does this need to be replaced or would it be okay on a simple trail bike? Any help would be appreciated!

  5. Any advice on what should be replaced while I have the top end off for a valve replacement. Will do headgasket and springs of course, anything other parts you would recommend while I'm going at it? Thanks!

    Oil puddles in valve cover?

    Hey guys, just curious as i recently bought an older crf450 and I am doing my first valve replacement myself and as I pulled off the valve cover there was a large pool of oil around the springs. Spark plug is dry. Is oil in the valve cover normal? Trying to find any extra parts I might need to replace while I have the top end torn apart. Thanks!
