    @dan28 I doubt the coolant volume being an issue

    Would it not be the same as using your bike with a low coolant level as this radiator is 15cm shorter so quite a bit smaller

        @dan28 no it wouldn't since the radiator will be filled to the top regardless so there's no air to expand

            My temp gauge barely goes up a CM, only time it went up halfway was when the head gasket blew on the hot day (2 days ago). I could run a 15cm smaller radiator on my bike without heat issues.
            Put a 12v fan on it with a temp probe to the radiator and it’d be fine, IMO...

              @spookdog after measuring the finned part of the gas gas radiator is only 15cm its literally half the size of the original
              I remember callum saying he had issues with his bike running hot an he used the standard radiator
              I would rather use a radiator closer to the intended size

                @dan28 according to the vapor unit, it was sitting at 100 celcius in traffic. Which seems way too hot.

                  I always thought ideal temp was as close to 100 as possible? That’s why the radiator cap is pressurised, to stop the coolant boiling but get it up there? I might be wrong, it’s been a long time since I looked into it and it was a car...

                    @spookdog not sure on my temp gauge when offroading in summer I would consider 110 Celsius to be time for cooling down since the motor would be smelling very hot

                      Using the twin rad setup that you have now how far up does it go when in traffic

                        It’s weird, my temp gauge doesn’t rise much at all in stop~start nightmare traffic. What does happen is my gear change gets ’sticky’, it won’t go into neutral without a struggle. That’s when my engine smells hot.

                        Trouble is a radiator is doing next to nothing if it doesn’t have any airflow forcing convection. Sitting in traffic is the worst possible scenario. I don’t have any cooling problems, if I did I’d put 1 or 2 12v fans on the radiator. The kind you get in computers for CPU cooling but bigger, there’s loads out there. have a temperature actuator probe that sits in the fins of the radiator, so they only come on when needed. If the problem was bad I’d shroud the fans th the radiator as well...

                          @spookdog the sticky gear changes might be your clutch overheating and putting pressure on the gearbox

                            Makes sense, especially when I ride the clutch like a numpty, rather than putting it in neutral, or just slowvertaking the stagnant traffic! 🙂

                                      @dan28 I did, but it is WIDELY different to the OEM Lanza radiator.

                                      I wonder if there was a translation error 😮

                                        You can buy a pair of after market lanza rads for approx 150 on the non filler side is a lot longer
