My 48 gets only 35 miles before reserve light comes on, so it's about 23 mile/gallon, is it normal? I have V&H short shots, SE stage 1, and dealer download remap installed, any one has the mod please post your gas mileage, does PC V get better miles?
Thanks

 

It's probably just your light.

 

Never trust the light. Fill your tank, ride 50 miles, fill your tank, see how much gas you've lost.

 

In town ....high rpm and/or using 1st and 2nd gear only....maybe.

2.3 gallon tank. Reserve light comes on with 1.3 gallons remaining...is that accurate?

35 + or - mpg around town might be what I'd expect.

How do the sparks plugs look? Could be running rich since you've updated fuel maps.

 

Seems a little low for a bike..

 

The dealer download is EPA approved so it's in the lean side,not rich.
How does the exhaust smell. Does it smell rich,like unburned fuel,have you got a fuel leak.
Forget the idiot light. Fill up the bike,bring Jerry can,ride til empty then report back. I get mid 40s with slip ons,fuel pak so your mileage is insane. How does it run

 

Using the light to measure miles per gallon is not very reliable. The light could come on early or late and throw off your calculations.

Carry a pen and paper with you when riding and when you fill it up write down the total mileage or write the mileage on your credit card receipt if you pay that way. When you get home subtract the mileage from the last fill up and see how many total miles you've ridden. Divide that number by the gallons of gas you just purchased.

That will give you the miles per gallon for that tank. Do that for several fill ups in a row while trying to fill the tank to the same level each time. That will give an an average miles per gallon over more miles which will better represent your bike's mileage capability.

After doing that for a while you'll get an indication as to the miles per gallon on tanks where you've done different types of riding (city, highway, aggressive, etc.).

If you keep doing this for every tank you'll have an indicator if something changes because you'll notice a drop or an increase in mileage.

If you really want to track this, it's fairly easy to set up a spread sheet to automatically do the calculations for you. I've used Excel for this purpose for several years for both cars and motorcycles.

 

i get about 36 on mine per G.
v+h str8 shots

 

It's the sensor in the tank. Mine was bad it wouldn't even come on. Or it would come On shortly after I would fill up.

 

I have the PC-V/re-map, open element air cleaner, and shorty pipes and can go about 55-60 miles before the light pops on. Thats with no tank lift. I fill up by 65-70 max. It runs out at max of 75 miles. Comes out to 1/1/4-1 1/2 usable gas out of the tank before the pump cant suck anymore gas out of the 2.1 gallon tank.
