125-200cc WRE 125 problems/tuning

Morning chaps, looking for some advice on my wre 125 2008.

Firstly does anyone know what engine parts from the WR125 or even CR125 will fit? E.g reed valves and cage.
Ive read something on here about fitting a WR head to the WRE, what would i gain from doing so? ( at a guess more power? Im thinking along the lines of the WR head having bigger ports?)

Also im looking for some jetting set up's to try as mine bogs in 1st and sometimes 2nd, standard apart from fmf fatty exhaust and turbine core 2 can. Thought about fitting a bigger carb but i would like to keep the autolube.

Cheers for reading chaps.

wr and cr are basically identical apart from ignition system and kick stand. bogging issue is jetting and you will have to read your plug and make changes to suit.
the wre i am not familiar with presume the cylinders are the same but maybe someone elsecan shed some light.

Thanks for the reply jo, my plug is ok.
See if anyone else can shed more light on the reeds.

Cheers
