    I don't know I mean really it depends on what you put in it and the temps to whether you need it I'm finding this funny this seems to be a hot topic at the moment with YouTubers as their all a bunch of b!tchy girls on cam 😂 😂 😂 😂 😂

    but if I was gonna move one I would just make a smaller one and put it somewhere else but I wouldn't get rid of it I mean considering radiator caps are normally in front of you I don't fancy testing the safety feature I don't think it's that safe on a bike

      You want an expansion bottle.

      If you run evans waterless coolant, the coolant won't expand so they become unnecessary.

      But I would still have one.

        @calum this is not true if you heat something it will expand simple Evan's is not magic and I was definitely not insinuating to use it neither lol and I would definitely not wont to test a cap with Evan's in my radiator hot chemicals on your skin can't be comfy not calling you on this just think it's best we stay away lol

            @terry-tz I think I got the jist if it after a while so the Evans stuff even at max temp you can remove the rad cap?

                That's the whole point of the evans coolant. The temperature necessary to pressurise the radiator system is significantly increased.

                As such it needs a higher temperature applied to it in order for thermal expansion to be a noticeable factor.

                Hence why the coolant is used, it reduces the pressures exerted in the closed loop system.

                Most radiator caps require .3 bar of pressure to actuate. In normal operating procedures, evans coolant doesn't hit this sort of pressure, ergo an expansion bottle isn't necessary for most of the yime.

                But I still run one regardless.

                            Evans actually run hotter than normal cooling, so yeah, not for me either.

                                it was probably just a way to save money I mean really you could make any bike not need one or car but it's more of a safety thing really

                                      @jens-eskildsen Ahh but you're missing the point slightly there.

                                      It may run hotter, however there will be less pressure exerted in the cooling system. The result is less strain on the cooling internals.

                                      The fact it has a higher boiling temperature also mitigates against the risk of localised boiling on the cylinder head, offering a more even distribution of thermal expansion.

                                      Again, this is all theory bull.

                                      It has been proven to have advantages in its own right. I'll agree and say I may have not noticed them.

                                      Remember, the heat of the flame under the spark plug is a damn sight higher than the coolant temperature. So if the coolant raises by a few degrees, this should still be lower than the heat of the piston crown.

                                      http://papers.sae.org/930217/

                                      So long as the heat within the engine resides within the temperature specified by the manufacture, there shouldn't be a problem.

                                        If coolant is boiling, something is off. youre not curing anything by changing the coolant to something that isnt boiling at that temp, but is actually running hotter. Thats treating symptons, not fixing whats wrong.

                                        I kinda like this one 😄 https://www.youtube.com/watch?v=VACKWvcXbXA

                                          @Calum

                                          Have to say though, heat transfer is interesting in wankel designs.

                                          But, If your worried about cylinder head localised boiling in a modern 2stroke!?

                                          then you have completely missed the point also.

                                          You could run a 4stroke for longer on alcohol based coolant, sure.

                                          What benefit to a 2stroke engine at least, does Evans coolant possibly have to performance?

                                          Its a negative in almost all aspects of operating temperature.

                                          Keep it real
