DIY in South East Asia

Hello and thanks for the add.  On my 5th visit to Cambodia and seeing many expats with DYI rigs. Poorman pickups.  I reside in fFlorida and own several classic bikes from 350's to 1100 cc.  Inspired by these homebuilts to fab up one when I get home in April .  Hoping to do some research here. I have mig. welding skills .  Just don't want to reinvent the wheel. Questions to follow along with pictures of the rigs I am seeing here in Asia.
