Planning on doing a little "freshening" of my 426 engine. I estimate I have put probably way OVER 200 hours on my bike. I have never had any sorts of problems or abnormal noises or anything, lots of compression still, and I have kept up on my basic engine maintenence (valve adjustments, oil changes, clean filters, etc) religiously since the bike was almost new. I am simply planning on doing this for peace of mind, rather than to correct any specific issues. I was planning on a piston & rings, cam chain, and possibly valve springs. Anything I am leaving out that should be addressed? Anything I am planning on replacing that is probably not necessary? The bike has been so stinkin' reliable for me I just wanna make sure she stays that way!
