and give your carb a good clean
these 125 models were tuned to the max to begain with so most mods do not help and the one for a smaller front sprockets
is a bad one
read about my sprocket mod and go for one that gives about 55 or 60 mph
55 or 56 teeth on rear 52 if its 17 inch wheel
mine runs at 69mph WFO and it is very hilly where i live with 60 or less sppeed limits
and i weigh 230lb i am in the usa and stones are what we put on a country road to get the mud under control

Sorry about the comment about getting a full licence, i had no idea that it was that sort of money. Next year it will be 40 years since i passed mine.
Is it a 5 or 6 speed box then?

if the oem sprocket is dished cut the center out to make a spacer to make the chain line up
