primmy 100/ pk hub conversion????

[jiffy]

Hi guys , need some help with regards to knowing if a pk rear hub will fit onto a primmy engine. the scootershop that i bought all the bits from thought it would work and it was going well ( ie modified pk shoes to fit etc ) but as soon as you wind any lock on it tightens up to much??
i am also using 10" wheels front and back if possible because i have pk125? forks in the front , it also looks like i will have to modify the downpipe on my new polini exhaust as well as it stops the wheel going round.....any help muchos appreciato!

Hi thanks for replying!! that was the question i forgot to ask and if i replace the backplate is there any mods to do this and will the shoes fit on without modifying them or grinding the **** out of them??
the spacer behind hub nut is a massive wide one....?
are you running 10" wheels?
and does anyone know if pk forks will allow primmy mudguard to sit flush with frame as mine seems to have about an inch and a half gap....plus my steering lock does not seem to work?? just goes on and on!!!!! thanks

backplate straght swop when using pk hub no need 2 alter shoes just bolt on pk forks need modifying 2 fit [stops foul] +sits higher ,if u are changing forks try et2/4ones ,use the big washer on pk rear hub otherwise it dont hold down, steering lock wont work unless modifyed
