BruceWayne911 Posted August 3, 2021 Share Posted August 3, 2021 Is there a specific temperature I should watch out for when riding my MT-07? My bike routinely reaches as high as 200-230°(Fahrenheit). Is this normal or something I should watch for? Link to comment Share on other sites More sharing options...

If a person wants to maximize their cooling system they can take a tiny pick and clean and align the radiators cooling fins, change to fresh coolant, make sure the hoses and cap are in good shape. 1 Link to comment Share on other sites More sharing options...

What temperature would raise red flags for you? Link to comment Share on other sites More sharing options...
Triple Jim Posted August 3, 2021 Share Posted August 3, 2021 The owner's manual says that if the engine temperature is too high, the red overtemp warning light comes on. 1 Link to comment Share on other sites More sharing options...

BruceWayne911 Posted August 5, 2021 Author Share Posted August 5, 2021 I've also started turning the bike off when stopped in traffic to reduce high temps. 1 Link to comment Share on other sites More sharing options...
Triple Jim Posted August 5, 2021 Share Posted August 5, 2021 This graph may put your mind at ease a little. It's one reason why I'm not jumping on the chance to make my fan come on earlier than Yamaha designed it to. Link to comment Share on other sites More sharing options...

Continental primarily makes air cooled aircraft engines, so I assume the temperature in the graph is cylinder head temperature (most piston aircraft have a gauge for that) not coolant temperature. I am not sure how closely coolant temperature relates to CHT, however I am not worried if the temperature rises while I am stopped or moving slowly as long as it does not go too high (which it never has). 2 Link to comment Share on other sites More sharing options...

This one allegedly came from GM and specifically says "cylinder wall temperature": 1 Link to comment Share on other sites More sharing options...

Consider this - while running coolant flows to the radiator and if it gets to a pre-determined temperature well below the critical level the fan will kick on. When the engine is shut off coolant doesn't flow, engine is still hot and not shedding any heat. Which makes sense? That is why there is a fan on the radiator. To make it cool as if the bike is still moving at whatever speed the fan runs. Much better. Edited August 5, 2021 by klx678 4 Link to comment Share on other sites More sharing options...
FZWes Posted September 4, 2021 Share Posted September 4, 2021 While moving unobstructed here in Vegas in 105°+ temps 178°-185°. While sitting in traffic 210° and thats why I refrain from riding in this insane heat. Link to comment Share on other sites More sharing options...

While sitting in traffic 210° and thats why I refrain from riding in this insane heat. 210° is totally reasonable. that isn't boiling temp yet and the whole reason for a pressurized cooling system is to raise the boiling point enabling coolant to keep drawing heat beyond 212°. Fact too, is that coolants and antifreezes also raise the boiling point making 210° no problem. But I think my own boiling point would be exceeded by 105° making me go search for a way to lower my temp when it gets over 90°. Link to comment Share on other sites More sharing options...
