Restriction will only be down to exhaust and air flow. You Could do some porting work but not the best of engines for that.

All the will in the world wont see it go above 15-16 bhp but you can make it a bit more responsive.

Std will be about 14bhp

Have fun.

i had a rieju rs2 nkd 50, and i de-restricted it byt taking a small valve out of the part of the exhaust where the end can is joined to the expansion chamber. all i does is restrict the airflow.

you may also have one where the manifold comes outta the cylinder head.

nah there aint no restrictions bud its a 4t , as aid best bet is to fit a decent pipe and filter and re jet it , i have had two xr 125s and both i done this too with other mods and surprising how much more pull there is at the top , but if you're really hank after more grunt its 2t all the way.

im hopefully picking my gs up this Saturday and have some intentions over the next few moths to play with it both engine and chassis so if you like buddy i would be willing too meet up and maybe discus how you could squeeze a bit more grunt out if you're interested as im basically in the same boat now but i have a action list lol
