How many miles are on your scooter? The small springs dictate when the clutch engages. You need to pull it a part and have a look.

Agree with Abner, but it may just need a clean up. Open it up and do a good inspection of the belt, rollers, clutch bell and pads. Meanwhile, if it is not jumpy when running, off the stand and sitting on it, I don't think it's worth worry about too much.

not jumpy when off the stand, i do hear clanking noise from clutch area, and when i roll the bike backwards the rear tire starts to lock up.

You don't really need any special tools. Take it off the centerstand and have a fat chick sit on the bike and gently squeeze both brake levers. The clutch nut will come right off.

I dont think i will have a problem getting it off, i know a lot of fat chicks! i do want to have replacement parts on hand and be able to torque it properly when i reinstall it. using an impact wrench as well

Don't use impact wrench to reinstall! Use a torque wrench

The more refined amongst us use torque chicks for this purpose. They come in many beautiful colors, but you have to choose the one that is right for each torque value.

But yes, no impact tools for installation!

In my experience the rear wheel spins whenever the engine is running and the bike is on the center stand. I push the sole of my shoe against the side of the spinning tire and, if I can stop the tire pretty easily, it's all good. If you can sit on the scooter with the engine running, no brakes, and it doesn't try to creep forward, you're ok.

That is fully correct.
Test this before disassembling anything.

But there was one thing Highhook wrote that is abnormal:
"when i roll the bike backwards the rear tire starts to lock up"
That should not be.

Time to open it up and take a look. I'd not be surprised to find a broken or dislodged clutch shoe spring.

That could well be the case.
And would also explain why the rear wheel tends to lock up when you go backwards.

Thank you all, for the responses, they were very helpful. After removing the variator and clutch, it ended up just being some maintenance.

The roller and tabs changed in variator.
Tabs loose and rollers worn.

New belt, old one probably still good

Clutch pack with new lg spring installed
O rings and oil seals changed and regreased
The clutch seemed very worn, also noticed clutch nut was touching bell housing
The old spring was at least 1/2 inch shorter the new one I installed
Seals and O-rings good, grease was shot
Don't know if clutch nut loosened, or was not torqued correctly

All in all, no more clanging, no more creeping, quiet and smooth ride.
