Subd for info...
I own the exact machine for my son, only it's in the 2003 Kawi variety (exact machine built by Suzuki, just with green plastic). Mine runs great, but I'm always looking for info to stay ahead of any potential issues.
I'll say this, the spark on mine doesn't look all that impressive either, but she fires right up! I've been through everything on mine except the case and head (carb, fuel tank, fuel lines, oil, chain and sprockets, greased).
I only wish the little guy had a tab more oomph.
Good luck with yours, your grandkid(s) will love it!!
