A little in-depth insight on rollers/pulleys?

Custom rollers or police have now peaked my interest since I've changed my v belt and realize how easy it was to get in there as before I was intimidated by the process.
I've been reading a bunch of things on this very form here about rollers and pulleys and it's a bit over my head. But some of the stuff I've gathered is depending on the weight of your rollers or pulleys you can change your acceleration or your top speed or smoothness of the transition of speed. When I hear the most talked about is Dr pulley which I think is a clutch AND roller replacement I think.
A starting question I have is if I install this system will it remove or reduce that to 2000 RPM delay where as soon as you hit 2000 RPM you actually start to move and it's quite a jolt forward and when you decelerate it suddenly abruptly clicks off into "neutral" or is that a design choice / feature of the bike? (Because as the way it is now stop and go bumper to bumper traffic is a nightmare trying to not over rev while being so close to other cars.

Another question I have is what kind of weight do what as in which ones give you top speed and which ones give you acceleration and also which ones are close to stock as possible.?

28 gm Dr Pulley sliding weights (aka Sliders) are as close to stock 28 gm roller weights as you can get.

No, changing to sliders of any weight aren't going to change that clutch-in at ~2000 rpm. And when decelerating, when the rpm drops to that same 2000 rpm the clutch shoes disengage and you notice that sudden lack of engine braking.

Theoretically changing to heavier weights, say 32 gm, will give you better fuel economy and more top speed —because you’ll never reach rpm red line. However it’ll take you quite a few miles at WOT to get to 60 mph. And you’ll never have enough oomph to pass that slow tractor trailer up ahead.

Dr Pulley also make a highly regarded HiT Clutch which locks the clutch shoes to the clutch drum and prevents the clutch from slipping. The HiT kit comes with an assortment of springs with which the user can alter the initial clutch engagement rpm, say lower or higher than that 2000 rpm, as well as springs to also select the rpm at which the shoes will lock up to the drum.

Hmmm very interesting, thanks for some information, and I'm assuming that lighter weights are the ones that give you more initial acceleration and less top speed?

That’s correct.

Do you really expect to be going over 100 mph? I suspect that, given this urban traffic, you’d be looking for better mid range acceleration.

And, yeah, along with this urban congestion your clutch is going to glaze and start squealing too.

Does that stop and go traffic make the clutch squeal? Because mine does every so often. If I hold in my breaks and accelerate for like 5-10 seconds it goes a way for like 2 or 3 months

Next time you're in there have a look at the clutch too, it's like a drum brake in reverse.
And while your at it give everything a good clean so everything moves smoothly.

 Yep. That’s clutch glazing.
