I have a 2016 KX450f that was completely submerged (I'm an idiot) when it had 4 hours on it. I got as much water out as I could and I had to ride it home which was about 15-20 min. I then did repeated oil changes until the oil came out with no water and cleaned it all up. Since then I've ridden it with no issues.
Fast forward to now and I have 10 hours on it and checked the valves. All 4 were outside spec on the tight side by about 2 hundredths. I've had them shimmed, but what other problems am I looking at? If the valves are shot would they be more out of spec than that? Should I be tearing it apart and having a look? The dealership advised to ride it a couple more hours and check the valves again but I'm paranoid about a catastrophic failure. Any advise?
