The 28 will only give you a couple more mph on the top end, and is harder to tune.
the 21 is easy to tune and uses less gas.
I vote 21mm

The door swings both ways, I want a trail tech but its a PITA to find something like that over here. The language also restricts me too, my wife helps but then fights with me for spending money on my scooter!

Taida?! Nice, how much USD was it?
And whats the specs on that crank?
Use the 50mm bore, thats supposed to be about 82cc with stock crank.

It was something like 42$ plus shipping 27$ it is designed for high performance kits, (or so they said) With a strengthened connecting rod
They have a stock one for 32$ and two stroker cranks for IDK how much.
They sell a bunch of performance parts for DIO engines including a 56mm (I think) water cooled bbk kit including electric pump radiator pipes and connectors! Very interesting!!
