I bought a used Swedetech built CR125 kart. After reading a ton about fuel, I settled with Sunoco 110 Leaded Race Gas (I wish the airport would let me buy 100LL, would be much closer).
I also adopted a jetting chart, which was made with VP98 Fuel and 24:1 mixture.
I don’t plan to race. So I don’t mind going oil heavy (and I guess leaner).
Now, Swedetech (and Honda) recommends 32:1 mixture. Swedetech specifically says Maxima 927 Castor (which I do have). I also have Red Line Synthetic Racing Oil as well.
So if I go 32:1 with Castor, and add some Redline, resulting in somewhere between 24 and 32:1…is my jet chart valid anymore? Should I do another chart for 32:1?
Would it even be valid for 24:1 with 110 Octane (I would think so at Octane is anti-knock)?
Is 24:1 right for CR125? It sounds like a lot of oil.
