Kawasaki Vulcan 1700 Vaquero Full Synthetic Oil Change Kit (2011) - Motorcycle Maintenance for Long Rides & Cruising

The kit should contain two washers, since there are two oil drain bolts. The same problem as last time. Thankfully I had an extra washer in my toolbox. The syntheticoil will give you smoother shifting. I am not a big synthetic oil fan, but it works. Thank you
