The engine runs at around 120 celsius.
I'm using Tornado 16%.
Also I changed the carb for the EVO3 STI as with the stock one the engine was untunable.

its quite hard to indicate what is the coz..you should at least get a minimum of 5-6 minutes runtime per tank
i suggest u check
1.your centax spring tension. maybe not enough tighten
2.your low needle
3.your main needle
4. also your idling should not be too high.
