I need advice on how to private sale my beautiful 2012 KS. Everything short of surgery has failed and I've pretty much wrecked my wrist trying to ride this bike.Can you guys tell me the best/safest way to private sale a high dollar bike, right down to payment,road testing,etc. I still owe $14+ and just want to be able to pay it off and walk away clear.

I have broken both wrists and have sympathy for your pain.
If it is the acceleration you can control it. Some days I have to just putt around.
If it is the clutch you can buy a larger slave cylinder.
The throttle never bothered me, but you can get cruise control and mess with the springs for easier turning. I keep mine lubed up.
There are smaller brake master cylinders available but be careful here. The brakes can get grabby instead of easier.
Selling on eBay is popular, just take your time and hold your desired price.
