When is the last time you COMPLETELY disassembled your carb for an unbelievable cleaning?

Where goggles, carb cleaner is murder on the eyes!

I haven't checked the valve clearences yet but it sounds like I probably should.

I missed a half a day of riding a couple of years ago just because of a loose spark plug cap. That is going to be the FIRST thing I check from now on if the bike's not running right.

Partial failure is rare in my experience.

If you have not checked recently, the accelerator pump on the 98/99 is NOTORIOUS for getting crapped up and seizing. Water goes down the accordian boot that seals up the AP actuation rod. I silicone mine on both ends now.
When you take apart your AP, BE SURE you get BOTH O-rings re-installed! One is famous for falling out. You will develope an air leak w/ that missing.
Use carb cleaner AND compressed air to THOROUGHLY blast the air ports that reside under the air horn. This would be your pilot air jet and main air jet. These can, and will, plug up from a freshly oiled (over oiled?) air filter.
Check your float height. These models were also sensitive to float level. Thoroughly clean all jets/ports on the rest of the carb as well.
