Buy a manual,follow what it says to do. use the proper tools for each nut and bolt,dont over tighten. if it doesnt work from there,then you need help. Right now,you need a manual.

Why ?
 
The easiest way to screw something up is to try to "fix" it when it ain't broke.

What elSid says. Get yourself a manual, you can always sell it on eBay when you get rid of the bike, although I nearly always keep mine.

Checking compression makes sense before tearing down the motor. Easy and cheap to do. Even if it does need work, the compression check can often detect issues between bottom end and top end that you won't necessarily see once the motor is apart.

The days of perking up a power-plant go back to the late 40s or early 50s basically on British irons.  We did it all the time, but to perk up a power plant like the one you mentioned is sort of a waste of time.
 
If you had the knowledge, the tools & time you could perk it up a bit, but nothing outstanding for I must admit that the JPN m/c makers built them better then the British did when in England.
 
If you pull one apart you will be amazed to find small ends are with needle bearings, & where the British used bushings the JPN makers used proper bearings.  So really all you are looking at is to replace the stock piston & rings for one bbl that has been honed out at a cost & some work on removing all the crap in the carb, to lighten things like sprockets, but remember lst you will probably have to replace the NEW chain with NEW sprockets.  Little things that will not give the bike a maze of extra power.
 
 


Remember all the others on the road are crazy & out to kill you.
