It's always a good idea when ever you own a new scoot, get as many repair books as you can on it and just look through it!
I think the owners manual with the bike tells how to adjust it??
You also have to consider clutch oil when you look to see where it "grabs".
If'n it's cold and you have a heavier clutch oil, it'll "slip" more, til it warms up.
It may grab different cold/warm/hot.
A thin oil like ATF will make it, "grabbier" .
Best bet, take it back to the dealer and let him adjust it to spec, order a manual, ask how you can do it.
I tell my sons, "is it slipping? Is there "free play at the lever? Yes? leave it alone!
Just my 2 cents!
