The Suzie GS line is nearly bulletproof, except for the electrics. They are known for burning up stators and regulator/rectifiers. The stock items are pretty weak. If you find yourself in need, be sure to use the Electrex replacements. Sturdy and cheaper than stock. The problem is well documented on the GS Resources site. If you pick this up, that’s a good site to hang around
