I'm needing to change my belt and rollers and I'm curious about the weight I should get for dr pulley sliders. I'm about 155lbs and my scooter is lightly modded.

A common rule of thumb is that Dr. Pulleys are 10% lighter than the original.

Based on somebody's recommendation here, I'm using 9g sliders in my stock '09 S150. Stock rollers are 10g, 19x17mm. I don't feel any difference except, likely, durability. YMMV on whatever "lightly modded" means.

No difference at all? I'm looking for a bit more jump off the line.
I was planning on going down to the Vespa shop to get a set of Sliders for my '09 s150 and a few other maintenance items......

Experiment with lighter weights if and as you please…trial and error with roller/slider weights is not my idea of time well spent.

The best upgrade for a little more oomph off the line IMO is a larger idle jet. Size 38 from stock size 35. Quick, easy, inexpensive, no experimenting.
