Zombie, I am located in the island of Bermuda. Have been talking to the Kymco dealer but not much info offered on my upgrade. I am basically the first person to perform the conversion. I really need to know if the 125cc crank will be okay for the 300 upgrade of do I need to swap the cranks? And like you said, I may need machining work done. How do I find out this information??.......I really don't know.
Hopefully someone on this forum will have an answer before I order any parts. If this don't work, I will be willing to drop to a 200 upgrade.
Thanks,
Agilebda
