What is your clutch doing that requires you to open it up? The needle bearing went out on my 125 at about 12,000 miles. I pulled a low mileage used one off my donor bike. I picked this up as a spare: https://www.amazon.com/gp/product/B07Z5 ... UTF8&psc=1 It looks to be very high quality. It has a review or two from an actual Buddy user.
I place the big nut in a bench vise and use a strap wrench to spin the assembly to break it loose. I then squeeze it together with a couple of quick clamps, and finish off the nut w/ a pair of channel locks. Use the Harbor Freight pick set to remove the small springs.

when i accelerate from a stop it doesn't move right away then jerks hard. after that it moves normal once I'm moving. I changed the rollers and belt and it still has this problem.

A few other things you can try-
-hit the faces of the variator with some sandpaper to remove any glazing
-with the scooter running squeeze both brakes and give it some gas, this can sometimes deglaze the clutch bell(I have heard some people say it doesn't do anything)
-you can take the clutch apart and make sure the clutch bell is clean and free of grease/gunk, and then make check that the clutch pads are clean.

These have worked for me a few times when the CVT started to jerk on take off. But I have also had a couple of clutches that got so bad the scooter wasn't ridable(it was popping wheelies from every stop.) My theory with these bad clutches is they need to be taken apart and given a good cleaning, then re-greased. I haven't been able to open one to test my theory.

Yes, some fine sandpaper is your friend here, same for my Burgman 400
Lightly sand across the shoes.

Thanks for the suggestions. I bought the clutch from the link and will install it next week when the tool to hold the variator and clutch from spinning comes and i have time. What is the tourqe number for the nut on the variator and also for the clutch nut?

Locking torque:
1.Nut of driving pulley M10:4.0-5.5kg/m.
2.Locking nut of clutch M10:4.0-5.5kg/m

I believe that converts to 29-40 lb/ft
