About this part
The cylinder head on your GT 650 Comet EFI seals the combustion chamber and carries the valves, camshaft and ports. After overheating, cracking or a blown head gasket, replacing it is often cheaper than a rebuild.
Frequently asked questions
What should I check when buying a cylinder head for the Hyosung GT 650 Comet EFI?
The engine code of your GT 650 Comet EFI decides fitment, not the model year - a head only fits its exact engine variant. Also confirm whether valves, camshaft and a gasket set are included or whether you are buying a bare head.
Is a used or reconditioned cylinder head worth it?
A professionally skimmed and pressure-tested head is usually the better buy than an unverified used one. Ask for the flatness record and leak test, and always budget for a new head gasket and head bolts.
