Short term maintenance on my Vulcan 750 consists of changing the oil and checking the tire pressures. Spin in filter. Hydraulic lifters so no valve adjustments. Spark plugs and air filters every 20,000 miles or so. Coolant change every 2 years. That should be about it. But then there's the final drive. Very poor design by Kawasaki. You have to tear the whole rear end out of the bike to lube the splines every 10,000 miles. Rear wheel, gearcase, swingarm, shocks, brake parts, and complete exhaust have to come off. Taking your time it's a 2 day job. I wouldn't mind so much if it was every 20,000 miles, I'd just do it when I replaced the tires. But you have to do it twice as often as replacing the tires, or the splines will chew themselves up, requiring a new final drive unit and drive shaft, about $1500. I did not know about this with my first Vulcan 750, but I liked it so much that I bought the '02 knowing what I was in store for. One of the first things I did when I got it home from the dealer was to tear it apart and do the splines. Sure enough they were bone dry on a brand new bike. These bikes were made unchanged for 22 years. The most likely reason there are not that many of them still around is that most owners never knew about this issue, destroyed their drive splines and gearcase, and sold or parted the bike out rather than spend the money to fix it. They also had issues with the automatic cam chain tensioners, but a set of manual tensioners at around 15,000 miles fixed that problem permanently.
