Starts off a little fast since clutch bell is spinning slowly; should not move. Does not seem to go full range for speed-up. Now have to inspect front pulley. Never saw top of belt in rear pulley...

Should I remove that paper thingy don't know what you call it so we can see the belt in the back?

Don't know what paper thingy... this last video actually looks pretty normal but I don't know what rpm's were. The CVT should be about max shift by 6000 or 6500 rpm. Clutch should not start turning until 2500 to 3000 rpm. Now, it looks like the belt is fully out at the start, fully max diameter on rear (clutch) pulley. What weight and type of roller/slider do you have in front pulley?

OK last video it did not move cause I only reved it up to 5000rpm and stopped.  Next video I kept going past the 5000 to a bit over 7000 rpm.  This is all I can tell you.  The rollers put in were not the Kymco rollers but I believe if not mistaken were sliders that would fit my bike.

Maybe they need to check my meter if it is reading working proper?

This guys seems to work smoother and better than mine does.  I have to hold my throttle at a steady climb and than it starts to move at about 5000 and up rpms

Clutch with OEM rollers (15.5 gr) engagement should begin about 2500 rpm which would be abour 15 mph (22 kph). 5000 is too high...

So would you say it has to be either the rollers/sliders or the belt or both?  Any other possible solutions.  My goodness I am being a pain lol.

On my bike the belt on the rear (clutch) pulley rests slightly above the top of the pulley; yours is slightly below it, which will cost you a little in top speed, I believe. In other words, your belt is a little narrower then mine. Probably nothing to worry about, your variator is doing the job. You might see if your belt is 25 mm wide, which is what specs call for.

Yes I am taking the bike in the shop early in the morning and I am going to bring this to their attention along with what size weight my rollers are to.

Maybe it would help more if I made another video while also recording the RPM on the dash?  This way you can see the belt turning and parts moving while also showing the rpms.

Yes. Side by side, simultaneous would be ideal.
