Moped Army

Hello swarm!

So, I'm in the planning stages of a west coast ride from Mexico to Canada this coming spring. I have an '80 Motobecane Le Moped in pretty much stock setup right now, munis the 15/16 Dellorto.

What I'm wondering at this point is if I should venture into upgrading my whole setup before the trip (and potentially risk creating problems down the road...?), or just do a LITTLE tweaking on my "so far trustworthy" stock setup. I'm not tooooo concerned about speed going up the coast, so upgrading for performance isn't the top priority; its reliability I'm after...though a few more mph and low end wouldn't hurt. Currently I top out around 35-40? (havent GPS'ed it).

AND, has anyone done this trip recently, and has the sage advice I'd pay for?

Again, this is a very preliminary gleaning for any advice/opinions.

Cheers!!!
