Hello from Philly

[Nemesis8]

Hi guys and gals. I'm new to the forum and somewhat new to the world of scooters. I own a 150cc Jonway YY150T-4. It's basically a Yamaha Zuma clone. I've owned it for 3 years now, but I'm just starting to make upgrades and mods to it. I've already gotten plenty of useful info from this site so I thought I should register so I could make some post and get some custom help. About to install a new exhaust and need some advice.
