Clutch problems

[JT]

I have a 2016 Bintelli Scorch 50cc. I had to replace the stock clutch 2 days ago. The clutch is a New replacement. Not upgraded.
when I installed the clutch, it matched up with the splines. No binding at all ,it retracts properly. I installed a new gates powerlink belt
729 17.5 , cleaned variator and replaced the wieghts with 4.5 & 7 gram staggered. I also replaced my 2 year old carburetor,with a new 18 mm carburetor with 85 main and a 32 pilot jet. I had fired it up adjusted the idle screw to under 1k rpm. The back tire had went from spinning constantly,to slowly spinning. I can apply the rear drum and the tire will stop. As soon as I let go the back tire slowly starts to turn. I ran the scooter lean and then rich. I checked throttle points from the carb the the handle bar. Please any info would be of great help.

Unless you are on the scooter and the rpms are enough the you can feel it pushing you forwards the its an idle issue.

You have to understand that the rear pulley/clutch rotates(on bearings) on the input shaft of the transmission. There is going to be some friction acting on the input shaft causing it to rotate.

Thank you , what can I do to take care of the friction then? I have had the idle screw so low and the wheel was still slowly spinning on the scooter and while running on center stand. While on it u can feel the load at a stand still. Never had anything like that happen.
I have tried researching and YouTube. It does sound like there is friction when I rotate the back tire while the scooter is off/not running.

Its nothing to worry about. If you off the stand and you need the brakes to keep you from rolling forwards its a problem.(idle is too high and clutch is engaging) Tire spinning on the stand at an idle is normal.

Its the same thing(sorta)happening here in this vid. This is in neutral, no gears are touching. The viscosity of the oil is causing this.

The variator will rotate with the crankshaft. The belt will be tight enough on the variator to get moved, and in turn move the inner(clutch shoes) of the clutch. The clutch shoe carrier will rotate as long as the engine is running.
If the shoes cannot rotate freely without turning the bell, if the shoes touch on the inner surface of the clutch bell, and drag, then there's something wrong with the shoes/bell/springs. The bell(outer) should be able to rotate freely without touching the clutch shoes.
Before installation, the bell should be readily fitted and removed from the shoe carrier portion. There should be no 'interference'.
All that said, you should be able to rotate the rear wheel with little resistance, mostly from the gears and bearings in the final drive gearcase. As you apply force to rotate the rear wheel, the shaft will rotate, turn the gear on the shaft, which will rotate the intermediate gear, which will rotate the output(input to the gearbox) shaft, which will spin the clutch bell. The bell will rotate about 11X faster than the rear wheel, and should rotate mostly freely.
There should be little power transmitted from the engine to the rear wheel when the clutch is not engaged, just the friction of the bearings inside the clutch.(the bearing between the clutch shoe carrier and the output shaft(bell shaft))
