What about spark plugs and valves?
I pulled the two outside plugs today (the easy ones) and they were identical. Clean with no deposits. I'd say that they look brand new but that would be a slight exaggeration. My gapper indicates slightly less than .035" so even though it's approaching the edge of the envelope, they're both within spec. (.031" - .035").
Unless I detect any deterioration in starting or performance, I'll pull 'em again @ 50,000 mi. By their looks, I'll extrapolate service life to exceed 100,000 mi. We'll see.
At 15,000 mi. I had a service check done and the valves were within spec. no adj. necessary. At the time, the mechanic said that they shouldn't need to checked again. I'll save the $165.00 service fee and buy fuel.
What a great bike!
Later.
