Sprocket recommendation 82 GPZ

So it's time for a new one.
I have no idea what is on it now, but factory is 16 front 38 rear as far as I know.
I do mostly highway 84 miles round trip on my daily drive to/from work. About 10 miles/day is city.
Should I stick with the factory (or what ever is on there now) or would you recommend something different?
Occasionally I'll take it out on the windiest road I can find for some fun, but mostly it's cheap enjoyable transportation.
Also, to confirm that I'm not being overly cautious, is there a way to check the chain's wear without taking it off the bike? I know the method is to hand a weight on it and measure the distance between a given number of links, but is there another way?

Stock specs it is.
I'm thinking my best bet is JT sprockets:
Front :
Rear
Chain is looking like an eBay deal .
Anyone got better ideas?
This is a *simple* installation as far as I can tell, remove the rear wheel, remove the rear sprocket using the allen-head bolts, replace, re-install the rear wheel w/o the chain.
Remove the front sprocket cover, chain, remove the sprocket (I'm assuming it's bolted on?), replace.
Then install the chain and tension it.
Anything I should be aware of? Should I use a rubber mallet for installing the rear wheel bolt or will it slide in easily? I don't have a dead blow hammer since I rarely need one.
Anything I'm forgetting?

I just replaced the sprockets and chain and had to have my son stand on the rear brake pedal to lock the system up, while his friend pushed on a 6ft pipe attached to the breaker bar as I heated the countershaft nut to a dull red with a torch.
It was fun.
NEVER use red loctite on the shaft threads (as I did 2 years ago) or you will need a pipe and two friends to get the sprocket off in a couple years.

The countershaft bolt is the 3/4" diameter bolt that runs through the rear wheel?
I loosened that last year when I adjusted the chain, no problem, but I didn't take it the whole way off. Or is this not the bolt your're talking about?
Do you know what the torque spec is?

I hope I don't have to put a torch to that.

I'll pull the cover off and check.
I've also got a 1 1/2" socket that I tried to get a water heater element off with. Using a 3' pipe, I had that 18" breaker bar bent like a banana and it wouldn't move. Didn't try torching it because it was installed in a "closet" and thought replacing the water heater would be cheaper than replacing all my stuff after the house caught fire.

Doesn't the GPz550 have the countershaft sprocket held on by a lockplate that is retained by two bolts?
Yep that is the setup on the 550's lockplate held on with 2 6mm bolts. Piece of cake to change.
