Has anyone have this setup running at sea level? I was considering getting this setup but found out I would have to run a mix race gas. I had called Carls and ask them if there setup would run at sea level on pump gas and they said no. I wanted it to run on pump gas only. I trail ride here in Iowa,wisconsin,UP and you can't get race fuel at these small towns. I would of thought all I would have to do is change the cylinder head to lower the compression? Thanks!!
