You could check the valve clearance first, please refer to the user manual pp. 2-4 and 2-5, and if it is out of spec, adjust the valve clearance.

Before this bike I had never checked or adjusted valves, but I got a set of feeler gauges (around $10) to check the clearance. Checked them at 1100 and 4200 miles, they were good. Then at about 6800 miles three of them seemed to need adjustment, so I got the Yamaha valve adjustment kit that Badbob recommended (around $20), and did it. A little scary, but if the subsequent check comes out good - it's one more thing learned. If you don't feel up to doing either checking or adjusting - just have a shop do it.

PS didn't you have a "high idling" problem first, and you fixed it? Maybe, because it idles at less rpm now, ticking is more pronounced - for my bike, that's the case, it ticks loudest at lower rpm.
