Curious how much (if any) your mileage drops when putting in cams (say tw222 or 555's) and/or something like the fuel moto 107 kit?
Compared to a stock or stage 1 96cu bike.
Is it hugely noticeable?

I guess a normal dyna stage 1 gets like 280 k's to a tank. Whats that... like 180 miles?

 

Depends mainly on how you ride.
With the extra power we seem to play more which results in less mpg.
Our 106 on the back roads and riding by the speed we get 44-46mph but when we are playing it drops to 34-36mpg

 

I dropped 3/4 mpg....but it really is about how hard I am twisting. I have never been able to ride it easy for a tank to get high mpg average. My guess is that i lost 1/2 mpg after the build.

 

yOu serious Clark?!?! I don't think I ever got 46mpg even bone stock... I get about 39-41 now with my fatcat when I'm playing nice... about 36 when I'm not.

 

It's all in the tune boys.........I can ride "nice" and get 50+.... I can have a whole lotta fun and get 43.......100+HP and 100+TQ

 

It gets better with the 106 than stock did.
The engine does not work as hard. 60 and below I stay in 4th gear. It lugs if I don't.
When I am on the back roads my wife is taking photos so I stay close to the posted speed.
We live on a mountain so there are no red lights and only a couple of stop signs. for 20 miles.
It's 50 miles round trip to walmart. don't do interstate on the Dyna so I have no idea what it gets.
It is the quick take offs that gets your mileage.
I get 40-42 on my CVO 110 street glide loaded. Back roads that is.
Just remember I think I can, I think I can LOL

 

If your thinking about a 107 then why worry about gas? Like the others here hace said it depends on how aggressive you are with the throttle. Twisting full open uses a lot of gas --> a lot. Doesn't mean you can't ride fast, last year I was going to halifax and got 210 miles on a tank @ 80 mph on the highway, it was just like that on that day! And my sig pic is from that day only this was earlier in the day ( sight seeing ) The fuel consumption will not vary much from setup to setup, with a good tune as the Don pointed out!

 

I get the same MPG with cams, SE high flow ac and 2:1 exhaust as it did stock. I get 46 to 50 mpg.
