[QUOTE="rmc_olderthandirt, post: 1179068, member: 68872"] Absolutely! Without knowing if the new top end was a preventative measure or if it was done because the engine seized then it is simply that: an unknown. Let me ask you this: When you change your top end twice a season, do you have the cylinder replated or do you just replace the ring(s) and possibly piston? I would be very surprised if you re-plate twice a year unless you are a very serious racer. I doubt that unless the piston actually seizes the cylinder is not going to significantly degrade any faster with old rings vs new rings. So, hypothetically speaking, consider a choice between two bikes, both 10 years old, one has had the rings changed 20 times and one still has the original piston & ring in it. I submit that if you bought either bike and immediately refreshed the top end the bike that had the original piston would be just as good if not better than the bike that had the top end refreshed 20 times. After all, honing the cylinder down 20 times has got to take a toll. So, to reiterate what I said, a new top end is not a selling point to me, any more than a recent oil change, radiator flush or other maintenance item. Ryan: The first thing you should do with that bike is change the oil in the transmission. [/QUOTE]
