2017 Gas Tank on a 2013?

[Flytech99_imp]

I looked into fitting an RS tank on a 2014 DLX and was told the tank will fit; however, the filer cap is different and requires a second key.

And yes, that gold RS is hot!!! Very congruent look with the forks and shocks!

I aint gonna lie....
i want a 2017 gas tank real bad too...
just so I can paint it -exactly LIKE THIS~!

That gold color really shows off the curves around the knee area.

That bike is gorgeous

max mileage speed

Yes we have noticed that higher rpms,and speeds use more fuel, but that only makes sense.

Riding locally 45-60 mph on curvy backroads its not unusual for me to get close to 60 mpg. In which case I know I can go over 200 miles before needing to start looking for gas. Take a trip, with freeway droning, like my 700 mile trip back from Arkansas, 12 hours at 75-85 mph and I saw mpg drop into the upper 40s. When that is the case I know I need to start looking for gas in the 140-150 mile range. That would be true of most any vehicle however. It simply takes more fuel to push something faster. For the CB the break point seems to be about 70 mph. For continued high speed cruising one would need at least 5 gals or 19 L of fuel to guarantee 200 miles on a tank.

Even guys that are used to pounding out the miles would have trouble riding 200 miles straight without stopping, especially on a bike not designed to cut the wind or protect the rider .... like the CB.

Then there's the seat, which most people can't seem to ride for the 3 hours at a time it would take to run out 5 gallons of fuel in 1 sitting. lol

It's worse than that

Unlike an automobile which is these days carefully designed for aerodynamic performance, a motorcycle uses most of its generated power to overcome the resistance of the fluid that we travel in. (Car drivers generally have no idea that they actually travel though a fluid

The fluid resistance (and the amount of fuel we need to burn to overcome it) is not proportional to the velocity we travel at, it is proportional to the square of the velocity.

Which is why when we are afraid to run out of juice in a car, we drive in as low revolutions as the highest gear will let us do, while on a motorcycle we travel as slow as we can without being a danger to ourselves and those we share the road with.

True. And with their smaller fuel tanks the aerodynamic drag penalties can make themselves quite a bit more noticeable on a bike. Particularly out here in the west, where there can be long distances between gas stations.

Although my CB1100 routinely delivers about 45 mpg at 75 mph Interstate speeds, riding into a 25 mile headwind can drop the fuel consumption close to 35 mpg. As far as the bike is concerned, it thinks you're riding at a steady 100 mph and burns fuel accordingly. All that extra fuel is going towards overcoming the increased wind resistance.

I first learned this years ago on the first leg of a long trip on my old KZ. My first stop was 135 miles away in Flagstaff, which was easily within range of the bike. I rode blissfully ignorant into a 25-30 mph gusty headwind. About 30 miles from my destination, I surprisingly had to switch to reserve. As the reason for the increased fuel burn became evident, I ended up riding along the shoulder at 30 mph in order to make it on the 1/2 gallon I had left in reserve.

The *force* to overcome drag is proportional to the square of the veolocity. That's right. The *power* required (or energy per second, or fuel burnt per second) is the force times the veolocity, which means the fuel burnt (per second) is proportional to the cube of the velocity.

But then again, if you go faster, you spend less time... so fuel burnt per second is proportional to the cube of speed, but fuel burnt per mile is proportional to the square of speed.

Most people plan their stops in terms of range ("I shall stop every 200 miles"), but some do in terms of time ("I shall stop every two hours"), so these should consider the cube proportion.

Hi All CB1100 riders,
Let's start with 14,6 L tank that my 2013 CB1100A/5 SPEED was equipped with. So I was on my East Canada, 10 days, 80000 km  long trip and while cruising on a hwy at 4500-50000 rpm , I ran out of gas after 286 km..Sunday, 8 am...so I was very po'd being stuck 3 = THREE km away from a gas station.
When came back home, I started looking for a bigger tank. Before that long trip, I tested my bike max range on slower roads (up to 100 km/h) and was able to make 300 km and 320 km distance during second test...  fuel reserve (last bar out of 5) was already flashing for a long time, this is why I got stuck
What really sucks out fuel is RPM, especially on a hwy long distance trip. Fuel gauge has 5 bars, and first bar is still on solid with about 4.5L of gas in tank and starts flashing shortly after.
When in 2016, I inquired Samurider/Takashi (great man!!!!) , he only had 16.5 L for my 2013, and negotiations broke out due to thinking of buying 2017 EX model. By the end of May, I visited Honda dealer and looked at  2017 CB, red, dual exhaust, spoke wheels +++ with 14.6 L tank, I decided not to trade in my 2013 for '17 model, mostly because of its small, 14.6L tank, plus few other small things I didn't like about '17 model.
Got back to Samurider/Takashi and he had even greater news for me...OEM, pearl white, 17 L ( as advertised by Takashi), so I already bought/installed it. So far I know for sure that it holds more than 16.5 L.
With full (5 bars on fuel gauge) 14.6 L tank, I was able to make about 60 km before gas gauge dropped down 1 bar  to 4 ... and so on...BUT with  full 17 L ( 5 bars on gauge), I already made 120 km before gas gauge dropped down 1 bar to 4 . Given all this, my fuel gauge already shows full when about 12-14 L of gas is pumped in a new 17 L tank... and there still is room for few extra liters.
Summarize, I believe = depends on RPM , that I'll be able to make up to 360 kms before refueling if I bring  gas gauge down to the last bar and flashing position for a long time = almost dead empty gas tank and risking running out of fuel.

Just to add few more things..
In January 2014, I bought my bike as a demo with 4500 km from a Honda dealer + Honda Plus extended warranty that ends in March 2019.
After 15000 km,  I ditched OEM Bridgestone Battlax tires (poor handling, bad cornering,  and dangerous during heavy rain....  FRT was nearly bold but REAR still a lot left)  and purchased Michelin Pilot Rd 3 tires,  FRT-120/70 ZR18, REAR-160-60 ZR 18 (awesome tires.. I only use Michelin tires for my bike and 2 cars , including 2 sets of car winter wheels - NO substitute).
I now have 42000 km on my bike and will replace tires and all the brakes in next 2018 season/50+K.
With my driving habits and road conditions, I changed spark plugs and air filter ( all OEM) at 40000 km but these should easy go to 50 K...
I ONLY use Motul 7100, 100% Synthetic Ester - 10W40 MA2 motor oil and regularly replace it with OEM oil filter every 5000 - 60000 km.
So far, I did all my maintenance by myself, except tire replacement. I replaced  OEM = 18T front sprocket with 19T, and I keep my chain slack at 20-25 mm instead of 30 mm as per service manual, I carry NO passenger and nobody else ride my bike.
In winter, I will replace slightly wet rocker cover gasket.
I never took out my bike for a shorter run than 70 km ( after work ride), and  my longest run is 1200 km/day, very often 800-1000 km/daily when going for a long trip with my '07 BMW-1200cc buddy.
I am licensed automotive service technician with 30+ years of experience with the same make.

Hi Peter,

have you noticed any difference in fuel consumption after changing front sprocket to one tooth bigger one (especially at speeds 130+ km/h)? Any difference in acceleration? Steep hill climbing? High elevation operation (2000m and more above sea level)?

I'll appreciate anyone other's experience as well.
Thanks in advance.

G’day Jurlie and welcome to the forum. Let the search tool be your friend. Others have changed sprockets and there’s plenty of discussion about it.

Thanks! Will do!
