Ok I'm new to the motobike world and I was wondering if you have to go with synthetic oil or if that is just your best choice? Has anyone gone with the cheap wal-mart stuff. Also I was wondering what the best ratio is I have read several different things and I was just wondering what most people were mixing there fuel like. I have searched and only found a small amount of info, but I have never had good luck with the search on any forum. do very many people do a 7 mile commute one way on these, because I'm sure going to give it a try. anyway I look forward to visiting with everyone and learning all I can.
