Please Share: Tach Speed, Roller & Slider Grams, RPM Spring Used. Name of Parts

All spring ive ever seen for sale are rated as rpm to dictate their stiffness, 1000rpm,1500rpm or 2000rpm? Thats what i mean.

A weaker spring is no good to me at all, it will not allow me to set it up in a decent rideable way. Its fine on the flats but as soon as i hit an inckine my speed drops off, sometimes its ridiculous on hills that arent even all that steep. 20mph or less was not unknown on my a50 going uphill on my stock rated spring, no matter what weight rollers i tried. 1000 rpm Malossi was better on lighter rollers and the 1500 was even better yet. 2000 rpm rated was no good for me again on any rollers so thats just too stiff for a 4t 50cc i guess.

I cant live with a contra spring less than 1000rpm rated at all.

I really look. Says this spring 1,000 or that Spring 1,500 rpm better. But Roller weights matter.

Not once is Top Speed Number, Spring, Roller Weight. Three Things. Looking for 45pmh, 1500, 7.5 grams. Anything mentioning heavier than 6.5 in this forum, that mentions both spring rpm & top speed? Florida is Flat. I see some 7gram 7g, but the directions say +1g, so any reports about 7.5 to 10g rollers or Sliders.

Wanting to Buy Dr Pulley, what weight, what Dr Pulley and Spring = What Speed on the Dial?

And, I'm feeling a little peculiar.
