2005 450 SX Rebuild

Recommended Posts

Working on rebuilding an 05 450 SX. So far I got it torn down and I'm waiting on my parts order to come in.

I do have a question about the piston. I don't recall if I possibly did this or it was like this, but either way I wanted to know if I could run this for alittle while.

In the middle there is a nick that is about a quarter of an inch long and maybe a sixteenth of an inch deep at most. I went over it with 600 grit sand paper and smoothed it out. The picture is after I sanded it. Anyway should I be ok with just throwing a new set of rings in it and running it like this for alittle longer? If I don't have to I'm not planning on getting a new piston right now.

More pictures of the build will be coming.

I don't think a scratch in the top of the piston will be detrimental to it.

If it was on the side. Yes. Top no problem.
