    @declan simple, open the radiator cap. Fill the system fully. Start the bike(with cap off) and let it warm up. After a while, begin reving the bike a bit. You will, once the bike gets hotter, see air bubbles escape at the top. Once you have done it for ~15 to 20 minutes and most of the bubbles are gone, you're good to go. But first, make sure there are not any leaks. See youtube for examples.😁

      Once you get her running all sweet no issues, then you can look to tune it up and get a bit more power out of it.

          @declan Aww mate, you won't regret that purchase. Best place to start as well. Simple plug and play. But you will want the programmer too.

                  @irongamer727 I don’t know the specifics but it’s amazing the potential that the zee gives you do some research Calum swears by it,

                    It's an aftermarket CDI.

                    It's more power because the ignition curve is far more aggressive. Or rather, the ignition is remappable and therefore has the potential to be more aggressive.

                    There are caveats to this. In most instances, it's win win win, but if you suffer from a lean mixture, you can expect an increase in the likeliness of detonation.

                    IMO, buy if you want to tune. If you plan on leaving it stock, then don't bother. But then we wouldn't be having this conversation if that were the case.

                        @calum running the Athena 170cc and Arrow exhaust. Will there be a big difference? Will it rev higher or how come it can give more power?

                          @irongamer727 You probably won't gain higher revs, as unfortunately, the ability to rev higher is lost with the bigger bore.

                          But yes, you will be able to dial in the ignition much more towards the bigger cylinder.

                          I'd have thought there would be some nice gains with this and the bigger bore.
