Change them out when you get the chance because I just now fixed my 2010 Honda NT700V by changing them out and the bike hasn't been running for 6 months and I was starting to pull my hair out , I had already changed the most difficult to change sensor, thats the CPK, or Pulse Generator that is under the clutch cover forcing you to remove the exhaust and I beleive it was the plugs the whole time because I never got any MIL lights.
My bike only has 6800 miles on it and the plug ends went bad and started causing misfires and it dieing, but only once it heated up and only when I gunned it in traffic making it a very hard to spot and potentially dangerous problem if it happens to you at 60mph which it did with me. You know you will need them if you pull the rubber plug off the spark plug end and it doesn't say NGK on them. Its hard to read but its there. Mine say "TEL" TP05K02W, with some kind of Star Trek looking logo, and the TEL ones actually look better on the inside having a solid brass cap, and the new ones, NGK look identical but inside have a more traditional brass clamp style. The NGK part # is 30700-MEW-922, I got them from Partzilla.com, they were $10 each plus $10 for expedited shipping. $30 total, you will need two of them.
You pop your plug wire cap off the plugs, then twist them counterclockwise while holding the plug wire tight and they rotate off. Then remove the rubber shilding piece coupling the wire to the plug end and replace it with the NGK ones , and then screw the NGK plug on clockwise while pushing and it will get tight. Its pretty dummy proof and took me about 15 minutes once I got the tupperware off and I had my tank tilted up. That would also be a good time to change the air filter as its right there and is a pain also.
Half way down the page, DNKTNG posted the instructions with pictures. Bike ran perfect after replacing them, and was dieing allot before and missing some.

So I just had this issue start about a week ago when i'm accelerating at above 6,500 rpms the engine just starts hesitating and it just starts to feel like it's lost half the horsepower.:doh1: My only guess is that my fuel pump could be going bad but I think that's unlikely since my bike is...
