How do I make my Goped sport run faster? What would be the cheapest way/parts to replace in order to make it run faster than stock set up.
Which is better, upgrade to bigger engine or big bore kit?
Thank you in advance!

Larger drive spindle, diet or a tail wind.

Likely selling the used engine first then buying a replacement from DDM

with a 29cc engine, is it too fast for a sport? is it stable?
