2009 "Raven" model. I'm the third owner. Was purchased new in 2010 in Golden, CO. I purchased it in 2015 via Craigslist out of Longview, TX with 11,2xx miles for $3,500 cash. Just turned 50,4xx and haven't even had a valve adjustment done yet. 3,000 mile oil changes done religiously with Yamalube 10W40 conventional since taking ownership. Running 03-05 R6 header with Yoshi slip-on, DynoJet PCFC with Marthy's REV-A map, BlackPath block-off plates, NGK Iridium plugs.
No smoke, no weirdness. Daily 30 mile commute.
