A rear main seal or transmission input shaft seal can leak and oil the clutch disk. An aftermarket clutch kit is $250 or less, the seals about $120. All these seals can be replaced without opening the engine or transmission cases. The labor is what makes dealer cost so high for a clutch. The bike's rear sub frame and all the parts attached to it have to come off and the unit transmission slid off the back of the engine. 10 hours DIY labor wouldn't be too much to estimate but it's just a matter of removing one part at a time until the back of the engine is exposed, replacing the needed parts, then reassembling the bike. A manual details the procedure. I did this job at 192,000 miles on my 2007. The clutch disk was still serviceable in thickness but what forced R & R was the transmission input shaft bearing was worn and allowed the shaft to wobble and destroy the seal. Used eBay 40k transmission and a new clutch kit came to $800 in 2017. Hexhead drive shafts don't last forever but shouldn't need replacement or rebuild before 80 or 100K. Final drives can leak out of one of two seals. One seal is a messy rear wheel but doesn't destroy the final drive bearing right away. The other seal leak can ruin the bearing in short order.I’m pretty capable mechanically. I’ve not had much bike wrenching in my background but I’ve worked with tools in my hands all my life. I am pretty confident given the correct manual I can tackle pretty much anything mechanical. What other service items might be common on a bike with 40-50k miles?? The one I spoke with the owner about had just had the rear shock replaced, what’s the likelihood of the front shock replacement being in the on deck circle??? What else is common on these bikes?
