CG125 tune-up / degraded performance

[Ingah]

Am fixing up my CG125 for road use again (it's been sat unloved for at least a year so i'm probably being a little hopeful thinking about this already; before i've even tried to start her up / fix her yet, but here goes).

I remember when i first got it (December 2007, as an 02 plate bike with 13K miles) the bike was able to do 70mph for the first few thousand miles or so, and performance gradually declined despite me renewing the oil, spark plug etc, until in the end i would be lucky to get near 65 out of it (on about 21K miles - i'd done 8K miles in that year).

Any tips for "tuning up"/restoring performance (bar basic servicing tasks of course) as when i get it back on the road i could really do with it being as fast as it can be because i'll be using it on A-roads alongside my rather-quicker CB500. While i'm at it, is there any way of improving those drum brakes bar a conversion to a disc (which i'm not going to do).

keeep it in the revs longer before changing up, and drum will always be drums, not much you can do to improve on them, except give them a clean inside to remove the dust and make sure they are correctly adjusted, if over adjusted they will affect performance.
