I bought a 2015 Vulcan S ABS earlier this month with only 3500 miles in great shape. It's my first bike and I'm very pleased so far. After putting a few hundred miles of my own on it I want to do an oil change and chain lube just so I can have the peace of mind of knowing it's been done using high quality parts and lubes. I was looking at the owners and service manuals though and it calls for replacing not only the oil and filter, but numerous O-rings and hoses throughout the cooling, fuel, and brake systems based on the age of the bike. I get the value of preventative maintenance, but on the other hand it seems a bit excessive to replace all of these components on a bike with under 4000 miles. How strictly do y'all follow those time-based part replacements on your own bikes?
