Hi Tyaak, It's great to hear from Argo owners on the opposite side of the world. I think you must have lots of great places to ride but If you are as far north of Sydney as i think you are you probably have some really hot weather in your summers. I assume that your 2011 750 hdi is a liquid cooled Avenger but Argo's names are confusing 'cause I think there is a argo frontier 750 with an air cooled motor. The Argo experts on this site can be more help if you tell us a bit more about your machine. My friends in England call their Argos Argocats?? go figure? Do you get gasoline with much ethanol in it? Our regular unleaded gas has enough ethanol in it to cause trouble if it is stored for any time at all in the summer. Good luck sorting out your stalling problems.
