Chinese scooter starting mods

[NaturalFlavored]

Ok I was starting to enjoy the bike as stock, but the more I drove the more I realized what I could tweak, this will be my slowest build. First I changed stock clutch springs to yellow (raised RPMs to almost 4k before take off) which had the reverse affect I thought and increased top end. First day of riding take off was a little better and reached 80mph (8mph more).
Second the stock muffler (Chinese) crapped out (everything inside crumbled). So I modded a zxr1100 muffler to fit (Craigslist), sounds a lot better (more of a two stroke).
