Wanting to know what everyone out theres mixing the oil/fuel ratios at. Just got rid of a oil injection system on a 4 zinger. Anyone out there with one or something like it. I know there are a whole mess of 50s out there,

 

On 2 strokes with their factory Oil Injection system removed (or disabled), most people start with 32:1. Depending upon the unit's Plug Reading, they either increase or decrease the Pre-mix ratio. I've read some posts where people run 40:1 and others run 25:1. Most remain at 32:1. It all depends on your specific engine, its mods, your driving conditions, etc. To read your plug, surf: http://sportbikeguy.com/garage/floor/plugread.html

Hope this helps...
