Looks like your looking to do ez work on your bike. Just pull them out look at them if they look good put them back in if not change then, now you worked on your bike.
They will easily go 100K on a stock modern FI motor. Mine still look new at 10K. If I pull them I replace them. Do what the owners manual say as a minimum.
Still have a lot to do change all holes New tire on front and brakes all the way around. Going to South Dakota . But first Little Rock ARK. Thanks for the reply.
