Re: A cure for bad vibrations, spark plug caps!!
Making the bike even smoother than it was....
She got fresh plugs. In 2009 Yamaha spec'd the CR9E plug, so I went with that as the side gap plug always wear fast allowing the gap to change beyond spec. I'm not sure there is any evidence they burn any better.
Take a look here you can see that #2 and #3 are worn in pretty good as they are now OVAL SHAPED electrodes. The gap was way over 0.028" @0.038" Also the Manufactures gap said the NEW plug was supposed to be at 0.028". Only one was. So check those new plugs.
More fuel deposits on plug #2. Or is that the aftermath of finding a caps wire loose some 2000 miles ago.
