95' 750 Mag Milage

[Slydynbye]

I typically ride in the GA mountians. I always fill-up on the kick stand and don't stand the bike up while filling due to spillage. I have stock pipes that I have taken the baffles out and no carb or air filter mods. It's about as stock as you can get. I ride back roads mostly and don't tend to get on it to much. 40-50mph through curves and 70mph on highways, if I have to get on one.

You have successfully untuned your engine. Relieving back pressure without any other mods will give poor performance and bad mileage. If you can put the baffles back in you will probably see the mileage jump back to near normal. Now, I'll be quiet and see what the experts suggest.

My normal was also 115 to 125 to reserve when riding conservatively for the entire tank.  Lately I have been riding a little more aggressive making sure not being in someone's blind spot.    

Yes I was teasing Jerry a little about the speedometer being a little off.

I agree by taking the baffles out you increased the air flow and you are probale running rich now.

[Chad in Michigan]

no, if anything, hes way to lean. the bike is lean from the factory and by taking out the baffles, it leans things up even more than before.

[Jerry G Turner]

My mistake way to lean not to rich.

[hootmon]

My mistake way to lean not to rich.

I'm neither:
"way to lean"
or
"way to rich"..
Just ask my belt, my wallet, or my wife!!!  

And I can't remember if I have baffles or not..

And I can't remember if I have baffles or not..

Well, the whole topic is rather baffling...

[Slydynbye]

Like I said Experts....but at what? Baffling BS?   Bubbly Bacon ?

I would agree that removing the baffles would change the back pressure and affect the performance, but I would bring it to your attention that unless you are actually removing the baffles that are welded up inside the muffler and not just removing the resonator or end plate you aren't really changing the pressure just the sound. My wife's Magna has every mod from cutting off the resonator to removing the whole end plate without changing the fuel milage, but the Cobra Drag pipes with no baffles dropped her fuel milage approximately 5 mpg.

At last -- real data!

Thanks, Charles

So if it is just the resonators being removed then no carb modifications need to be done?  I bought mine with the resonators out already and wondered if the person did any carb work on it also.
