CMR 82cc Dio Big Bore Kit

My setup right now is:
AF16 on a sym dd50
CMR 82cc Dio Big Bore Kit
28mm oko carb with 130 main and 39 pilot
PG long
8.4:1 gears
ZX trans
Keli vari with 36g total
stock clutch
black center spring(unknown brand)
yellow clutch springs(unknown brand)
Don't have a temp or rpm gauge

Right now it doesn't want to idle unless holding the throttle a little. It also takes off really slow and revs really high before it start moving. The center spring seems to be too soft because as soon as I start moving (maybe 5-10mph) it starts to compress and belt starts to slide down.

Is it trans tuning or jetting?

jetting !

stop riding it like that or you may damage the bore.

way bigger on the pilot like 50 or 55

What about main jet? bigger/smaller?
And needle position?

Use the 130 and see how it runs, it should be pretty close.

Most of my bikes needle position is one up from center.
