still think you have a plugged carb passage somewhere maybe an idle air passage, you used carb cleaner and compressed air to blow this carb's jets out?

gauge shows hot but engine is not
fuses dont blow
could be as simple as a bad earth
or faulty temp sender

colour and level of oil
Hi Blu, I haven't had a motor bike for a while but is there NOW gearbox oil as well as engine oil???.... Use to be the same mate, You should ask next time you're in the local motorcycle store..... CHEERS..
Probably a carb issue. It sounds as though the idle jet is clear but the main jet is blocked. So your bike starts and idles, but as soon as you ask for more fuel, not enough gets through the main jet and the bike bogs down. Buy a manual and a can of carb cleaner, take the carb off, remove the bowl, remove the jets and leave them soaking in carb cleaner overnight. You might need to use some fine wire to poke through the jets if they are very blocked..
