Most people use the roller weight they heard was good in a forum. Their scooters will never show its full power because the roller weight depends on a lot of factors. Gearing, belt, variator, counterspring, jetting, rider weight and so on..
I guess your pm pipe is a pm52 and I dont know how much it revs. If it is a more high revving pipe than my pm59 11,5 might be good. 11,5 is probably close to the weight that would suit an mhr pipe and that pipe is screaming.
Try different roller weights untill you have found the best weight.
Good luck!
