There is plenty of information on checking stators and reg/recs on the interweb, just do a search, I had problems in that area last year on my ‘10 which I traced back to a reg/rec but I would say that most likely is not your problem.
It has very low mileage for a 22 year old machine so it’s probably sat around for long periods with old fuel which is going to clog up the injectors with a varnish like substance. A few tankfuls with a good injector cleaner added is going to be a good place to start, I use one by Wurth which seems to do the job. It will benefit from new plugs, filter, oil change and new brake fluid for sure. All easy to do, just get a manual. The airbox comes off with a few screws, there is one at the front buried behind cables/pipes which is a bit of a sod to get to. You’ll need a set of torx drivers. Then while everything is off, check vacuum hoses, stepper motor TPS.
