The seat is the wear item (valve wears some too obviously). I check mine at the beginning of every season. In the case of this engine, I checked them after my first oil change at one hour and after my third hour since everything was fresh. > > Doesn’t hurt to check. Normal wear makes them tighter, so quieter. Most people don’t think that way… sometimes buckets and/or lobes wear and make them louder but thats not very common after initial run-in! ahhh see back in 04’ I bought a brand new Honda 450R…That didnt come with titanium valves but I pretty much turned that thing into a tuna can within the first 3 motorcross races with it, so it didnt stay around long. Biggest waste of money I have ever spent On a side note, like I said, I am somewhat new to the 4 strokes…nice for you to correct me! --- _[View the full topic](https://forums.speedlife.net/t/2004-yfz450-470cc-suspension-work-possible-trades/252953)._
