I'm midway through my moped refresh. I haven't been riding my express much in the last 13 years and now I'm getting it back into service.
Everyone likes pics and I wanted to make this thread to hopefully help others in the future. I'll get some better pics up. These are from when a buddy and I were fixing up the bent pegs. We cut them off flush and forced a solid rod into the lower tube and welded it all back together. Pegs are solid now.
Polini 46mm kit
Boyesen dual stage MOD reeds
stock carb - jet drilled to 100 (FOR NOW)
slightly ported intake manifold
Hack/Weld Bi-turbo (just this and stock everything else netted me 38mph)
couple holes drilled in stock airbox
Oil Pump removed and plugged.
I can hit 41mph (gps) easy but am getting worried about RPMs.
How fast is everyone else going with their NC50?
Modify reed block? (cut the center support out?)
NR77 80/90-14 for the rear.
NU50 front 16" wheel/tire
Better rear shock
