checked the plugs fine...sparkplug caps horrendous. Spark had burnt holes in rubber booties on 3 out of 4 plugs...I read here there is a service bullitin on them...help me out please and let me know if yamaha will fix them for me...Thanks

My bike won't beat a Ninja 250 the way its running

take it to a dealer with a copy of the service bullitin and tell them they need to replace the, that they are obviously having warrenty issues and need to replace it...i wouldnt let it go.....my friend did that with his wrx (i know not an r6) but took the service bullitin in about his clutch being bad, and what not and they replaced the entire assembly clutch flywheel and etc
