It’s a 2009 K1330S, purchased with 9,000 miles. I replaced the clutch and ensured it was assembled and lubed correctly during installation and again after the basket came apart. It had never been touched before I got it, and the same was true of my last 2009 K1300S. None of the oil passages had been modified, bone stock. Never any clacking, chatter, or the host of bullshit issues some other folks chase for months.
The oil was Liqui-Moly 5W-40 and it was full with Mahle filter. Seriously, no wheelies or hard launches by me. I run it to 10-11k multiple times a day(commuting and weekend mountain fun), always use the quick shifter, and don’t hold it at high-RPM for any length of time or load it hard before it’s fully warm.
The coolant and oil were completely warm, 75 degree day, just midway through a 20 mile commute. The hottest it’s ever been is idling in traffic until the fam comes on for a minute.
In summation, I ride it as intended and am careful not to cause shock loads and premature wear. The only time it’s tapped the RPM limiter was when the basket let go. I’m in Colorado too, so it makes 140 or less horsepower at the crank, not stressed at all. I’ll get some pictures in the next couple days. I see the carbon marks on the inner hub, but it’s not grooved and nothing in the pictures has been wiped or cleaned.
