Anyone mess with s&s super E carbs?
So I got this electra glide. The owner before me slapped on a Super E and didn't do any adjusting. S&S puts a .0295 intermediate jet, a .072 main jet and a .040 main jet air bleed. I changed the jets to a .028 intermediate jet and a .066 main jet. The bike gets way better gas mileage and the exhaust sounds way healthier and louder. But, when I am cruising through the gears, at about 2500rpms the bike starts to lose a little bit of power until I crack the throttle and force the main jet to kick in. Ive read on here that it usually means its too rich at that point and needs a larger main jet air bleed to delay when the main jet starts. But to me it almost feels like the bike isnt getting enough gas in those rpms and forcing the main jet to kick in gives it the gas it needed and everything is fine from then on.
Any advice on what I should try?
I already ordered a .046 main jet air bleed so we'll see how that works out.

I currently have a 46 air bleed and plan on changing it for a 52 soon.
I didn't notice much difference with the 46.
Remember the intermediate jet works for the 1st 3/4 of throttle after that it is the main.
I would put the 295 back in and put in a bigger air bleed.
If that 46 doesn't work for you then you can drill it out to what you need.
Hope this helps.

IMO the S & S is the wrong carb to have if you are tuning for gas mileage...you would do much better with a CV...but you could still play with the .0295 and bigger air bleed to find a happy medium between running right and gas mileage...if you are cruzin around 3000 rpm, you may have the carb in the transition phase where it is running off both jets...killing your MPG
