Without any warning, suddenly, take-off with a very light throttle application produces
some harsh and hammer-like j/e/r/k-ing in the driveline.
When applying full throttle, it goes steady as long as it it climbing, but the j/e/r/k-ing starts coming back as
pull on the engine decreases.
Is this a spring issue inside the clutch ?...
Thanks in advance...

Failed springs in the clutch would prevent the clutch from releasing, but I can't see how they'd affect the gripping part. Have you pulled stuff off to check? I'd bet on a belt issue. Hopefully not stripped gear teeth or splines somewhere.

Right, will pull cover for inspection.
Expecting replacement pipe from graphite9 soon.
This scoot gets lovin' then...
You have mentioned two things that could have easily gotten overlooked Wheeldude...thanks..
I my mind's eye, I see something amiss in the variator/ramp/weight/area.
The violent nature of the malady is unsettling...

If it's sharp, hammer-like hits, park until out-sorted. Tac-tac-tac can wreck other good stuff. Even a crankshaft.

My buddy had a ramp guide snap and in turn rollers were sneaking out from behind the ramp. Made quite a racket for sure. Finally pulled the cover and 3 of 6 rollers were loose and destroyed and the plastic putter shells and some of the metal insides were Jammed in to the clutch took forever to clean up. I definitely wouldn't continue to ride until you pull the cover.
