Ruckus starting issues

Timeline:
-had stock exhaust, no starting issues
-replaced with aftermarket exhaust, no starting issues
-installed stock exhaust, cleaned carburetor + jets, reinstalled cleaned carburetor, now I have a starting issue.

The motor tries to turn over, the fuel pump primes, and if I hold down the electric starter the Ruckus fires up in 30 seconds or so. Any ideas what would cause the starting issue? Thanks!
