Well this being my first 4 stroke in about 15 years I decided to have the stealership go threw the 10 hour inspection. I had a little over 10 hours(no hour meter yet) and no valves needed adjusting. Only issue they found was oil under the dust cap, they replaced the seal and everything seems to be running just great. I’ve seen friends check their valves themselves and looks easy enough...but being my first 4 stroke I felt more comfortable bringing it back to Yamaha to see what they said. On a side note- I was figuring some valves would need adjusting because the first 4 hours on the bike weren’t the easiest but im glad everything is in top notch shape for the time being.
