Last tank, hit reserve at 80 miles. Around town riding, keeping the noise down.

 

Fill it up, ride for some time, maybe 70 miles or 100 km then fill it up again then figure the miles/kilometers per gallon. Do it a few times with random types of riding and you have a good idea of when to fill up. Everyone is a bit different, based on gearing and all. With stupid low 13/47 gearing I filled up around 100 miles But figure it out for yourself, our experiences could leave you walking... and cursing us!

 

I've been playing with the idea of moving the rad overflow / reservoir to where airpump & smog junk was over the cylinder head. The extra room in the rear can then be used for an auxiliary fuel cell.

 

I found a Baker distance tank a few years ago and removed my overflow...still haven't found a good place to put it...so I've been running w/o.
I've only had a drop or two come out of the overflow line and that was when warming up the bike right after removing the bottle.
Found that stupid cap screw when I went to check the coolant level, it must be a lawyer device, coolant level was fine.
Maybe if you lived in the south, you'd need the overflow.
If I were to take off for the TAT or something, I'd add it back on just for insurance.

 

I dont trust the 100 miles per tank so I bought one of these on Amazon (RotopaX RX-1gallon gas pack) to carry on my luggage rack. It will only increase range one extra gallon but sure helps when in the woods.

 

keep in mind, this is my numbers from my stock bike,

with the exception of the jet kit. still good fuel mileage.

no gps, or aftermarket calibrated speedometer.

numbers are coming from the stock speedometer/(really the odometer) that came with the bike.

odometer gets reset every time I fill up.

if I flog it, high 80's before I flip it to reserve,

and I have ran out of gas before, but there is one stop on the way back home less than 5 miles from where I ride.

the numbers I am referencing are from the stock speedometer/ no gps gadgets.

your numbers may confuse someone with a stock set up. causing them to fill up more frequent.

this bike holds 2 gallons,

normally when I stop for fuel I'm just under and gallon and half to full again.

1.4623 gallons

If I had to use reserve its usually right at a gallon and a half 1.5 gallons.

I can go three days, without filling up, my trips are short though.

and before that I was filling up with fuel everyday, at 0.352 gallons, which is a waste of time.

perhaps the post should have read: what number does you odometer get to before you have to refill!

as you and others have mentioned/ and proved that the speedometer is not correct as it should be.

 

some reason I thought I used to put in around 1.8? gallons
which if true that means I was really close to hitting reserve at around 60 miles when I would fill up
because I know ive been around 70 before when I hit the reserve



I was able to run my ims 3 gallon tank until it ran out of fuel this weekend, to get an idea of what to expect

half of the tank was freeway speeds, other half 40 mph or slower speeds
so its a good average of speeds I usually do

I hit reserve at 115 miles which is great
but I just started to hit a hill
I think if it was flat ground I probably could of went a little further



and totally run out of gas at 135 miles which was 20 miles on reserve flat ground


so I get an average of 45 mpg at least this 3 gallon fill up




so with the stock tank I would make sure to full up around 60 miles just so I dont hit the reserve accidentally depending on how I drive


Im thinking with the 3 gallon tank maybe fill up at 110 miles so I dont have to hit the reserve

so thats almost twice as far as before compared to the stock tank

 

I know now how far I can go on the odometer before turning the fuel selector to 'reserve'.

I used to leave it selected to 'on'

when I get close to my mileage for fueling I know I am almost out of gas,

but I just leave the selector to reserve, that way if it does run out of fuel from the top of the first half of the tank, I don't have to stop. the fuel selector is already on reserve.

it will go completely empty from the whole tank left on reserve,

just remember by your odometer when you need to fill up.

 

It depends on how many times I fall over! Gas runs out of the carb pretty quick. Without falling over 100 to reserve.

I ran out of gas yesterday due to this very problem. I called my wife, luckily I was on a paved road at the time.

 

It has been a while and I just figured out that if I wanted to do the math exactly here is my formula.

90 miles indicated on the trip meter divided by 1.3 gallons (roughly figured as indicated on the gas pump meter) equals to 69 miles a gallon for me last time I filled up with fuel. I run 87. Anyone else use anything besides 87 octane?
