Default Another PreMix/Carb Question.....

Here we go. I'm getting ready to mix a fresh batch of gas and would like to try a richer (more oil) ratio. I currentely run at 50:1 and want to try 40:1. Would this require re-jetting? My thinking is no.......

I dont think you will need to rejet. Switching to 40:1 is a good idea too

Adding more oil will actually lean your mixture out. 40:1 is pretty standard around here for a 250. For 125's I would stick to 32:1.

I would definitely go with a 40:1 ratio over a 50:1.

I agree, 40:1 is a good idea.
