I never seen any metal filings in the oil and if there were it would be caught by the oil filter anyway.I appreciate the response- The dealer mentioned something about cleaning metal shavings from the break in but this kinda sounded like BS so just curious what everyone thought about the First Service.
I bring it back for a valve adjusment but just not at the first service. I worked at a Yamaha dealer for a few years while going to college and very rarely you see any movement in valve tolerances with so few hours. I'm waiting till atleast 150hours before I get them checked.One of the reasons for the break in "first service" is to eliminate any metal shavings that weren't caught during assembly. The other is to check valve clearance after it's been run for x amount of hours. If the dealer is checking the valve clearance it's not a bad idea but if there just changing oil then save your money and do it yourself. I always let the dealer do my first service like Viking2k14 said but specify I want the valves checked then do my own service after that.
Yeah true I've owned eight Yamahas from brand new in the last 14 years and have never had to adjust the valves on any, especially not at 20 hrs.I bring it back for a valve adjusment but just not at the first service.
