I got a Grubee Skyhawk and was wondering if they make a BB kit for these?
There really is no big bore kit for the 66 cc 2 strokes.

The 66 cc are kind of the big bore kit from a 48 cc but the parts
do not interchange.

Only Arrow Motorized Cycles makes a stroker crank for the Skyhawks
which makes them about 70 cc? and corrects the port timing.

Arrow makes the undisputed fastest race China girls on the planet.
