    @darty Go On...

    People swear by it.

    I'm running it, as on paper, I can see the benefits.

          @declan have you thought about just making it smaller and moving it

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

              @terry-tz it's not an issue I was just wondering why not all bikes have them

                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.

                          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

                            @jens-eskildsen In peak summer times, my DT recorded a temperature of around 110 degrees using my vapor unit whilst sat in traffic.

                            The water did not boil, but no doubt there was a lot of pressure on the cooling system itself. This was prior to using evans.

                            Ultimately that was when my bike was a commuter. It isn't any more and I doubt I'll be sat in traffic for long periods of time.

                            Where I will be ripping up the B roads the coolant will have plenty of time to regulate.

                            In this instance, evans coolant requires no maintenance. There is no corrosion to worry about and it doesn't require anti-freeze.

                            Therefore it offers minimal maintenance when compared to normal coolant.

                            For this reason, I will continue to be using it on my project bikes as they will no doubt be left in storage.

                                @jens-eskildsen I agree, if there is a problem, evans coolant isn't solving the issue, it's masking it.

                                I didn't have a problem, and I didn't mean to suggest using evans was an adequate solution to an overheating issue, as it is not.

                                        Never heard of them going wrong personally, DTRE doesn't have a temp gauge so it's never been an issue for me.

                                        They get hot but they keep running.

                                        You can get a temp sender for the vapor that screws in where the original goes. That's what I did so I have a nice reading on my unit.
