What are the oem stock roller weights in a Kymco People 150

[Billyntekea]

I'm ordering new rollers and i need to know the oem stock roller weight so i can order one size lighter rollers.
 Also if anyone knows the oem standard torque spring rpm rating...that would be great to know. I want to order a one size heavier torque spring. Would a 1000rpm torque spring be an upgrade or the same as the oem one.
 Aparantly the rpm rating on Torque springs eg.1k 2k is the delay in rpm before the clutch engages after idle speed. So if idle is 1500rpm then a 2k spring should engage the clutch at 3.5k rpm engine speed. Can anyone correct me.

Poking around it looks to be 15g.
I'd poke around the forum a bit maybe to see what others think, but with my S I went sliders not rollers.  Helped more than a little & I did kinda wish I'd gone a bit lighter like you're looking at; albeit the bike was liveable at stock with a slider where there was a huge flat spot with the stock rollers.
Springs?  No clue, never did change 'em 'em out.
