Im looking to buy an Aige clutch for my RH50 and I am trying to find out the factory clutch spring preload weight and what should I go to for more speed.

My options are 7.8 kg, 11.7, and 12.

Also what size are the stock roller weights?

Finally has anyone done a clutch on their Roughhouse or Rattler 50 and if so how well did it work?

havent done one myself but from what i hear the best is the Dr. Pulley Hit clutch followed by the Malossi Delta clutch. Thats one of the next things im gonna do.
