My mini bike has a Honda GX 160 with the govenor still installed. I am not removing it. I just ordered a 2 stage header, UNI air filter, a Honda GX 140 emulsion tube, and a #90 main jet for the carb. Please dont ask me to remove the govenor. My gearing is a 12 tooth clutch and a 60 tooth rear and my tire size is 4.10/350/5. I clocked it at 30 MPH on a GPS, but that was with the stock engine. Do you think i will get a noticable increase in low end power after i put all of these parts on? Let me know if you are running this setup and how you like it. Thanks
