Hi, what did you do to clamps, rims, starter pedal, did you anodize them? I powdercoated frame and rear arm, and used anodizing on all other aluminium parts. Still need to assemble the completely renewed 400 engine and will make sort of a black bike. Its current looks are like this Sorry if it interrupts your topic, just want to share same basics and worries of powder coating holding up on the rear arm. Oh, and I also chromed the rear spring.
