well, i finally got around to doing a bunch of maintenence to my R6, such as oil & filter change, coolant change, chain clean & lube, chain adjustment, shift link adjustment, rearset height adjustment, clean K&N filter, and finally.......change the spark plugs. i can't believe how bad i let them get this time. this is 12,000 miles of hard use. that center electrode is pretty oval compared to the perfect circle it should be LOL. anyway, i got a great deal on the plugs at the local advanced auto---like $5.90 each compared to the $14 each at the local Yamaha dealership.
