installed 551 cams and had it dynoed. Mileage went to crap. Since then I installed a S&S 106 kit with 585 easy start cams and a downloaded map.Only concern is gas mileage as bike runs better than I expected.So I'm wondering if I should connect the 02 sensors to increase mileage and if there will be a problem not having it re-dynoed.
mileage is upper 30's but never 40's even when just tickling the throttle
If this is what is to be expected , I'll live with it. Thanks in advance. I learn a lot on this site..

 

What device are you tuning with? Your mileage seems low...I can get mid to upper 40s two up but when I'm alone and using more rpm it drops to 40 mpg. Why not get it dyno tuned again?

 

Using a power commander. I didn't want to use the same guy that did the initial dyno as I felt he just added lots of fuel to the tune and he stated too many complain on the fuel consumption and he tunes for performance. I feel there can be a compromise as it is after all a street bike not a drag bike.. I plan on going to Doc Harley in CT. in the spring and getting it done.
I was just curious if I connected the 02 sensors if it would perform allright.
Thanks for the reply
