    Slow jets

    So I have '75 with pod filters and mid length 4 into 2 pipes, I put in 120 main jets and it does good on top end although I am going to try some 125's just to see if it gets any better...my main question is do I need to change my slow speed jets as well, they are the stock 40's. It bogs a little coming off of idle. I haven't heard much talk about the slow jets.

    Try adjusting your idle mix screws first. You may be able to adjust out most or all of the bog with the screws. I personally rarely change the slow jets, I can normally get the bog adjusted out with the screws. Only way to know for sure is to try, all setups are a little different and elevations and temperatures make a big difference in jetting.
