I do my initial start with 24:1 with about one cup of that mix after that I switch to 32:1 and have no problems. On my first bike I tried to do the 24:1 for the first 100 miles as per the break in instructions that I was given, this accomplished one thing, I was fouling plugs left and right. If I run a bike on synthetic I use a 40:1 mix...Kelly
