Well, I have decided that the time has come for the good ole' 400ex to get a fresh top end. It is running great, with no major problems, other than a minor amount of oil usage, and with approx. 250 hours on it, it is probably due.
I do have some questions, as I have never done this before:
1. Will a simple honing be sufficient on the bore being there are no problems like seizing, or other problems causing this rebuild?
2. Am I correct in thinking a stock size piston will be the one I should select, if only honing is done.
3. While it is apart, should I also change out the cam chain, tensioner, and sprockets at around 250 hours. Or, is that not needed.
4. Is there anything else that I need to check out while I'm in there?
