again, no melting issues on my bike. Just make sure your header won't touch the radiator bolts/rubbers. Use a grinding machine to fix that. Make the collector in that way so it's as far as it gets from the filter element. Also put in a sensor hole so you can easily do dyno runnings/mappings, see pic.
Do a lot of offroad events, the engine runs at high temperatures, but still no melting issues regarding the clutchcable/filter elements or radiator hose/rubbers. If you need anymore information pls let me know.
